F45 - Robotics, Automation, and Autonomous Systems

SCOPE
1.1 This terminology covers terms associated with robotic, automation, and autonomous systems. By providing a common and consistent lexicon, the purpose of this terminology is to facilitate communication between individuals who may be involved in the research, design, deployment, and use of robotic, automation, and autonomous systems, including but not limited to, for manufacturing, distribution, security, healthcare, response, etc. The terminology covers, but is not limited to, terms used in performance test methods of for example: robot arms, automatic guided vehicles (AGVs), autonomous mobile robots, and all other automatic or autonomous industrial systems.  
1.2 For the terminology to be harmonious with the practices in the field, definitions have been drawn from the literature or other public sources when possible. When no definition is available, is similar but requires change for use within standards produced by Committee F45, or in dispute, a consensus-based approach will be used to resolve definitions and add them to the lexicon. The development of this terminology is taking place in close coordination with corresponding efforts in all Committee F45 subcommittees to ensure comprehensive and consistent coverage.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 A-UGVs navigate, dock, or perform other tasks, or combinations thereof, within for example manufacturing, warehouse, hospital, and other environments. Objects (defined in Terminology F3200 as anything in the environment that is not infrastructure) and obstacles (defined in Terminology F3200 as static or moving objects that obstruct the intended movement) are common within these environments. Objects can cause A-UGV challenges in navigation, docking, etc. (see Test Method F3244, Guide F3470) where the object detection systems must provide the highest level of performance to allow safe and productive vehicle use. ASTM Committee F45 surveyed the A-UGV community of manufacturers, users, and researchers, and determined that a relatively short list of objects are the most common objects that their vehicles must detect and avoid. Additionally, ANSI/ITSDF B56.5 includes three test pieces that represent (1) the human body torso lying horizontally and (2) standing human leg, both with worst case, flat black coatings, and (3) flat objects (for example, boxes, doors, manufactured materials), including a worst case, highly (optically) reflective coating. The survey results are listed here and are considered example objects found in warehousing/manufacturing, healthcare, domestic, and retail environments:  
4.1.1 Pallets, racking, wheeled carts;  
4.1.2 Other A-UGVs or AMRs;  
4.1.3 Steps or stairs;  
4.1.4 Tables or desks, ladders;  
4.1.5 Cables or hoses, or both;  
4.1.6 Chairs, overhangs (that is, on objects);  
4.1.7 IV poles; and  
4.1.8 Forklifts/forklift tines.
As some objects may not be cost-effectively available for only A-UGV object detection tests (for example, 4.1.2, 4.1.3, and 4.1.8), the remaining objects are potentially more cost-effective as objects and are described in this guide as the standard set of objects.  
4.2 The objects can vary greatly within their category. For example, pallets can be made of wood, plastic, or metal; have a variety of ...
SCOPE
1.1 This standard guide provides a standard set of reference objects for use with automatic, automated, or autonomous unmanned ground vehicles (A-UGVs). The objects set includes typical objects found within industrial areas including, but not limited to: warehouses, hospitals, office spaces, and manufacturing facilities. Also, the objects set includes three test pieces from ANSI/ITSDF B56.5. The objects set is intended for use by A-UGV manufacturers and users to test the performance of A-UGVs when near the object(s). The objects set is minimized to include characteristics that have proven to cause interrupted A-UGV operation. Beyond this set of objects, Test Method F3418 is used to record most any object.  
1.2 The objects set contains one each of the following items: pallet, racking, ladder, cable cover, table, cart, intravenous (IV) pole, chair, forklift tines, and test pieces shown in ANSI/ITSDF B56.5, including a horizontal cylinder, vertical cylinder, and flat plate. The objects set is not intended to be exhaustive.  
1.3 It is intended that the objects set mainly includes off-the-shelf items. This standard guide provides a reporting method to provide obstacle information (for example, model, serial number, photograph) to allow obstacle use for exact replication of tests.  
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are not precise mathematical conversion to imperial units. They are close approximate equivalents for the purpose of specifying material dimensions or quantities that are readily available to avoid excessive fabrication costs of test apparatuses while maintaining repeatability and reproducibility of the test method results. These values given in parentheses are provided for information only and are not considered standard.

SIGNIFICANCE AND USE
5.1 A-UGVs operate in a wide range of applications such as manufacturing facilities and warehouses. Fig. 1 shows three example A-UGV types and test apparatus sizes to test A-UGVs intended for different vehicle tasks, types, sizes, and capabilities. Such sites can have both defined and undefined areas that are structured and unstructured. The testing results of the candidate A-UGV shall describe, in a statistically significant way, the ability of the A-UGV to navigate through a defined area with or without impairments. Whether or not an A-UGV is able to deviate from its path, or uses features of the local environment as input to its navigation method or both, should not result in a different test method. Rather, the capabilities of the A-UGV to adapt its navigation method in a given environment will be objectively determined by its performance in the test method.  
5.2 Three different manners in which a test method apparatus can be rendered are specified for use: physical boundaries, virtual boundaries, and floor markings (see Section 6 for apparatus specifics). Two types of impairments are specified that can be utilized as the defined area as part of a navigation test: obstacles and communication impairments (see Section 7 for more detail). The apparatuses and impairments chosen shall be appropriate to the application and environment in which the A-UGV will be used.  
5.3 These test methods address A-UGV performance requirements expressed by A-UGV manufacturers and potential A-UGV users. The performance data captured by these test methods are indicative of the capabilities of the A-UGV and the application represented by the test.  
5.4 The test apparatuses are scalable to constrain A-UGV sizes in defined areas to meet current and advanced next generation manufacturing and distribution facility operations.  
5.5 The standard apparatuses are specified to be easily fabricated to facilitate self-evaluation by A-UGV developers and users and provide practice tasks for...
SCOPE
1.1 Purpose:  
1.1.1 The purpose of this test method is to evaluate an automatic, automated, or autonomous-unmanned ground vehicle’s (A-UGV) capability of traversing through a defined space with limited A-UGV clearance. This test method is intended for use by A-UGV manufacturers, installers, and users. This test method defines a set of generic 2D area shapes representative of user applications and for different A-UGV types.  
1.1.2 A-UGVs shall possess a certain set of navigation capabilities appropriate to A-UGV operations. Two examples of such capabilities include A-UGV movement between structures that define the vehicle path or obstacle avoidance. A navigation system is the monitoring and controlling functions of the A-UGV, providing frequent A-UGV updates of vehicle movement from one place to another. A-UGV environments often include various constraints to A-UGV mobility, such as boundaries and obstacles. In this test method, apparatuses, impairments, procedures, tasks, and metrics are specified that apply constraints and thereby, standard test methods for determining an A-UGV’s navigation capabilities are defined.  
1.1.3 This test method is scalable to provide a range of dimensions to constrain the A-UGV mobility during task performance.  
1.1.4 A-UGVs shall be able to handle many types of open and defined area complexities with appropriate precision and accuracy to perform a particular task.  
1.1.5 The required mobility capabilities include either preprogrammed movement, autonomous movement, or a combination of both, from a start location to an end location. Further mobility requirements may include: sustained speeds, vehicle reconfiguration to pass through defined spaces, payload, A-UGV movement within constrained volumes, A-UGV avoidance of obstacles while navigating, or other vehicle capabilities, or combinations thereof. This test method is designed such that a candidate A-UGV can be evaluated as to whe...

SIGNIFICANCE AND USE
4.1 A-UGVs operate in a wide range of indoor and outdoor applications that include many communications challenges that can affect A-UGV control and monitoring. An A-UGV system or A-UGVS as defined in Terminology F3200 includes the A-UGV and all associated components, equipment, software, and communications necessary to make a fully functional system. Communications impairments can cause: (1) changes in A-UGV operation, (2) changes in behavior in system components such as control and scheduling, or (3) changes in operation or timing of infrastructure equipment coordination. This practice is intended to record the task performance of an A-UGV while communications are impaired in a specified and repeatable manner (for example, standard test method).  
4.2 Communications impairments can occur at a variety of locations within the A-UGVS. The network topology in Fig. 1 shows many of the common communications links that could be impaired. The numbered arrows in Fig. 1 label different places where communications impairments could occur. The box colors (that is, green, red, blue) indicate different types of impairments where the two red boxes are similar to each other. Fig. 1 will be used throughout this practice and included on the test report for use in describing the test setup and results by the test supervisor.  
FIG. 1 Block Diagram of Communications for Control/Monitoring of A-UGVs and Associated Facility Equipment in which Numbers with Arrows Indicate Examples of Communications Impairment Locations  
4.3 The requested expected results provide pass/fail reporting criteria along with recorded notes pertinent to the test or results or both. It is possible that the communications impairments used will have no noticeable effect, and this is often the desired outcome.
SCOPE
1.1 This practice considers impairments of communications within an automatic, automated, or autonomous unmanned ground vehicle (A­UGV) system during task execution. An A-UGV system typically uses communications between an A-UGV and fixed system components and resources, such as off-board control, job and fleet scheduling, infrastructure equipment interactions, or cloud-computing programs for tasks. Communications impairments can cause an A-UGV operation to change in various ways that can include delays or failure to complete the task.  
1.2 This practice is designed for applying known communications impairments to an A-UGV system in conjunction with A-UGV task testing. It is designed to create similar changes in communications that can possibly cause task performance limiting effects that are often experienced by an A-UGV system in different environments.  
1.3 This practice is intended to simulate impairments that may be present during the operation of an A-UGV system. This practice can be used, for example, by a manufacturer to indicate that system performance was tested to be robust against specific test communications impairments. The tests are not intended to test situations that should be eliminated during system installation, for example, a duplicate internet protocol (IP) address on the network.  
1.4 This practice only describes communications impairments. It does not specify an A-UGV task. The A-UGV task should be a defined ASTM International test method or task description in similar detail.  
1.5 This practice defines methods to record communications impairment types and extents while the A-UGV is stationary or performs a task. Temporal or spatial extents in which communications impairments occur include the timing, duration, location within the task, or other triggered events. Examples for implementing common communications impairments are provided.  
1.6 This practice is not intended for:  
1.6.1 Communications impairments between onboard components of an A-UGV, for example, onboard sensors-to-onboard computers.  
1.6.2 Communications or measurement impairments directly affecting external reference or p...

SIGNIFICANCE AND USE
7.1 A-UGVs operate in a wide range of applications such as manufacturing facilities and warehouses. The testing results of the candidate A-UGV shall describe, in a statistically significant way, the ability of the A-UGV to position itself at a fixed location or relative to a dock. This test method defines tests for use by manufacturers and users of A-UGVs to measure and record the docking performance. The test applies to different types of A-UGV, applications and test apparatus.  
7.2 Navigation—The test applies to all types of navigation. The capabilities of the A-UGV to apply its navigation method to a given environment will be objectively determined by its performance in the test.  
7.3 Vehicle—The test results of the candidate A-UGV will confirm, in a statistically significant way, how reliably an A-UGV arrives at a dock from one or more start locations. Refer to Test Method F3244 for typical vehicle configurations.  
7.4 Apparatus—The test method is scalable, using similar apparatus to interface to different A-UGVs.  
7.5 Defining a Successful Test—The probability that a repetition will be successful (R) and the confidence (C) in that probability are used to identify how many sequential successful repetitions are required to pass a test. The test requestor shall define these values and record them on the test report (see Appendix X1 Table X1.1).
SCOPE
1.1 This test method defines standard tests that demonstrate and confirm positioning of an A-UGV. Positioning, the repeatability of A-UGV location when stationary after completing maneuvers to a stop location, may be defined globally or locally relative to local infrastructure. The latter has become known as docking. See Terminology F3200-18a for terminology definitions. The test also includes a method to confirm the repeatability of height control of load transfer equipment, for example an A-UGV with fork tines.  
1.2 This test method is intended for use by A-UGV manufacturers, installers, and users to quantitatively confirm the maneuverability and repeatability of an A-UGV’s positioning or docking. Positioning and docking are similar operations and the tests described are applicable to either. The term docking will be used throughout this test method to include both global positioning and local docking. The tests facilitate comparative trials across a set of A-UGVs or multiple trials over a period of time.  
1.3 The tests can be carried out by many vehicles using different methods of location measurement and control to achieve the demanded performance. Vehicle configurations and vehicle components include:  
1.3.1 Vehicle load type (for example, fork lift, roller deck, trailer, flat deck);  
1.3.2 Vehicle drive mechanics (for example, steered tricycle, two-wheel differential, steered omni-directional or ‘mecanum wheel’ drives);  
1.3.3 Navigation sensors (for example, scanning laser, local beacons, floor marking, environmental features);  
1.3.4 Docking sensors (sensors, for example, camera, line detector, and laser scanner, which are used primarily for local measurement at the dock).  
1.4 The A-UGV may include roller tables, fork tines, robot arm(s) or other mechanisms to transfer the load or interact with the dock (for example, perform assembly). The standard test can be applied to A-UGVs with any of these load transfer mechanisms. The repeatability along each measured axis is measured and compared to a defined repeatability margin. The set of repeatability margins comprises the complete task performance margin (TPM).  
1.5 This test method shall be performed in a testing laboratory or the location where the specified apparatus and environmental conditions are implemented. Environmental conditions shall be recorded as specified in Practice F3218-17.  
1.6 Standard test apparatus is specified to be easily fabricated, facilitating self-evaluation by A-UGV developers and users, and providing practice for A-UGV developers, u...

SIGNIFICANCE AND USE
5.1 This guide is intended to be used by manufacturers and users of A-UGVs: (1) to fully define capabilities of their A-UGV(s) or (2) to allow the standard requestor to describe the A-UGV capabilities required for the requested A-UGV to align with assigned task(s). A-UGVs that are covered within ASTM Committee F45 are industrial vehicles that, for example, can be automatic guided vehicles through mobile robots, can be pre-programmed-through-autonomously controlled, can operate indoors or outdoors in infinitely diverse environmental conditions and therefore, with infinitely diverse functionality. To fully describe and measure the usefulness of these vehicles, functionality can be divided into categories where associated capabilities can be independently measured. This guide therefore provides a decomposition of many, perhaps not all, categories and capabilities that are typical of current A-UGVs globally marketed.  
5.2 Capability Categories:  
5.2.1 Goal Navigation: Pre-Programmed—Capabilities are the various abilities of the A-UGV to navigate a series of externally-defined waypoints on the way to a final goal.  
5.2.2 Goal Navigation: In situ—Capabilities are the various abilities of the A-UGV to navigate to a final goal by using the A-UGV system’s internal logic to determine the route.  
5.2.3 Localization—Capabilities are the various abilities of the A-UGV to determine its pose within an environment map.  
5.2.4 Docking—Capabilities are the various abilities of the A-UGV to stop at a position relative to another object or an absolute position in an environment.  
5.2.4.1 Infrastructure Dependence—Sub-category describing the need of the A-UGV to rely on features in the environment for Goal Navigation: Pre-Programmed, Goal Navigation: In-Situ, Localization, or Docking.  
5.2.5 Obstacle Avoidance: Single Vehicle—Capabilities are the various abilities of the A-UGV not to collide with an obstacle(s).  
5.2.5.1 Types of objects that can be avoided and are with...
SCOPE
1.1 This guide categorizes the autonomous capabilities of an automatic through autonomous-unmanned ground vehicle (A-UGV) based on the following list of capability categories:
(a) Goal Navigation: Pre-Programmed;
(b) Goal Navigation: In situ;
(c) Localization;  
(d) Docking—Infrastructure Dependence;
(e) Obstacle Avoidance—Types of objects that can be avoided and are within the A-UGV envelope, and types of objects that can be avoided and are outside of the A-UGV envelope;
(f) Changing Contour Area or Envelope;
(g) Changing Payload;  
(h) Impaired Communication Behavior;  
(i) Lost Communication Behavior;  
(j) Environmental Conditions;
(k) Fleet Makeup—Fleet Task Assignment, Information Sharing/Updating, Fleet Navigation Coordination, and Fleet Task Coordination.  
1.2 This guide provides a basis for A-UGV manufacturers and users to compare the intended task to the A-UGV capability. This guide does not purport to cover all relevant capabilities or categories that an A-UGV can perform. Instead, this guide provides a method for defining A-UGV capabilities and limits of A-UGV capabilities within specified categories listed in 1.1.  
1.3 One or more capabilities may be used to define the A-UGV capability and not all categories are required to be used for defining the capability of an A-UGV.

SIGNIFICANCE AND USE
4.1 This section lists and explains the characteristics that are used to describe a stationary obstacle.  
4.2 It is essential that sufficient information about the obstacle is recorded using this practice so that the obstacle can be replicated. This will allow comparisons to be made between test method performances that use obstacles with similar characteristics.  
4.3 Class:  
4.3.1 When describing an obstacle to be utilized in ASTM Committee F45 test methods, two classes are defined:
4.3.1.1 Genuine—The obstacle being described is an existing real world object (for example, a chair, table, machinery, or equipment). Any identifying information, such as make, model, SKU, etc., should be recorded.
4.3.1.2 Artifact—The obstacle being described has been constructed according to the characteristics outlined in this section. Obstacles of this class are intended to be replicable.  
4.4 Parts of the Obstacle:  
4.4.1 Each characteristic can be used to describe a property of the entire obstacle or a part of the obstacle. All parts of the obstacle must be uniquely named and identified in the test report described in Section 6.  
4.5 Shape:  
4.5.1 The shape refers to the relationships between the external, physical boundaries of the obstacle. All shapes can be in contact with the ground or elevated above the ground (see Fig. 1, Fig. 2, and Fig. 3). The unique obstacle shapes are:
4.5.1.1 Bar (for example, column)
4.5.1.2 Panel (for example, sign, pallet, shelf)
4.5.1.3 Cuboid
4.5.1.4 Sphere
4.5.1.5 Cone
4.5.1.6 Other—Obstacle shapes that do not fall into one of the above categories (for example, a pile of fabric). An obstacle can use a single shape to describe its overall volume or multiple shapes to describe parts of the obstacle. For example, the shape of a desk could be described as an elevated horizontal panel with two vertical panels spanning from the ground to the horizontal panel or the shape of a table could be described as an elevated hori...
SCOPE
1.1 This practice specifies physical characteristics that can be used to describe obstacles utilized within ASTM Committee F45 test methods. The obstacle characteristics specified in this practice are not described with respect to the manner in which they will be sensed or detected by an A-UGV. Rather, the obstacles are described according to their real world characteristics. For example, the real world characteristics of a wooden box that is flat black on one side can be described according to its actual dimensions, material, and color. An A-UGV with a lidar sensor may have difficulty detecting the side of the box that is flat black, which could make the obstacle appear smaller to the A-UGV compared to its actual dimensions in the real world. However, this may not be the case for other A-UGVs due to the wide variety of sensors used to detect obstacles, so the actual, real world characteristics are used to describe it instead.  
1.2 Real world, existing objects can be used as obstacles and described using this practice. The characteristics specified herein can also be used to construct test artifacts to use as representative obstacles that are intended to have similar characteristics to that of real world obstacles. The obstacles that can be described using this practice may be found in indoor and outdoor environments.  
1.3 This practice does not purport to cover all relevant obstacle characteristics that may have an effect on A-UGV performance. The characteristics specified in this practice are limited to the physical properties which are considered to be the most salient in terms of the effects they can have on A-UGV performance. As such, the user of this standard may select the level of detail to use in order to describe the characteristics of an obstacle in such a way. The characteristics are also limited to those which are more easily measurable and replicable when comparing test method results that use similar o...

SIGNIFICANCE AND USE
4.1 This section provides a description of the environmental conditions listed in Section 1 and describes the sub-conditions within each condition. Examples provided for many of the conditions and sub-conditions are provided as guidance only. Each of the conditions described should be evaluated and documented as set forth in Sections 5, 6, and 7.  
4.2 Environmental Consistency: Static, Dynamic, Transitional:  
4.2.1 Static is when the environment is similar throughout the test apparatus. For example, there are minor fluctuations in temperature throughout the apparatus as shown in Fig. 1 and Fig. 2. Dynamic is when the environment significantly differs within the test apparatus. For example, when the temperature changes between repetitions as shown in Fig. 3. Transitional is when the environment significantly differs in different areas within the test apparatus as shown in Fig. 4. The intent here is to not give specific guidance, but to provide a high-level classification of a particular set of environmental conditions. If environment consistency is dynamic or transitional, or both, a report form (see Section 7) for each unique set of environmental conditions should be completed.
FIG. 1 Example of Static Environment using Temperature
FIG. 2 Example of Static Environment using Temperature and Showing a Transition between Two Static Environments
FIG. 3 Example of Dynamic Environment using Temperature and Showing that the Environment Changed during the Test
FIG. 4 Example of Transitional Environment using Temperature; Portions of the Environment May Remain Static or May Be Dynamic (for example, Cold to Colder)  
4.3 Lighting:  
4.3.1 Various lighting conditions can potentially affect A-UGV optical sensor performance by affecting sensor and in turn, A-UGV responsiveness. Lighting sources can include ambient lighting as well as light emitters associated A-UGV operation. Two setups for lighting include direct or ambient source(s) applied to the A-UGV. Direct...
SCOPE
1.1 When conducting test methods, it is important to consider the role that the environmental conditions play in the Automatic through Autonomous – Unmanned Ground Vehicle (A-UGV) performance. Various A-UGVs are designed to be operated both indoors and outdoors under conditions specified by the manufacturer. Likewise, end users of the A-UGV will be operating these vehicles in a variety of environmental conditions. When conducting and replicating F45 test methods by vehicle manufacturers and users, it is important to specify and document the environmental conditions under which the A-UGV is to be tested as there will be variations in vehicle performance caused by the conditions, especially when comparing and replicating sets of test results. It is also important to consider changes in environmental conditions during the course of operations (for example, transitions between conditions). As such, environmental conditions specified in this practice are static, dynamic, or transitional, or combinations thereof; with the A-UGV stationary or in motion. This practice provides brief introduction to the following list of environmental conditions that can affect performance of the A-UGV: Lighting, External sensor emission, Temperature, Humidity, Electrical Interference, Air quality, Ground Surface, and Boundaries. This practice then breaks down each condition into sub-categories so that the user can document the various aspects associated with the category prior to A-UGV tests defined in ASTM F45 Test Methods (for example, F3244). It is recommended that salient environment conditions be documented when conducting F45 test methods.  
1.2 The environmental conditions listed in 1.1 to be documented for A-UGV(s) being tested are described and parameterized in Section 4 and allow a basis for performance comparison in test methods.

5.1 The significance of the information to be recorded in a test report allows for A-UGV performance to be contextualized with A-UGV configuration.  
5.2 Limitations of the practice are that not all A-UGVs have the same capabilities or configuration parameters. For example, for capabilities, a vehicle that remaps during navigation versus another vehicle that uses a static map may behave differently in repeated runs of an obstacle avoidance test. For configuration, a vehicle that remaps during navigation may have varying times that obstacles remain in the map for test recreation.  
5.3 The environment map used by the A-UGV, developed through localization including any landmarks, shall be saved as used on the A-UGV and should be saved and provided as a human-readable layout on or off the A-UGV (see Appendix X1 showing a sample layout drawing).  
5.4 The main A-UGV hardware parameters shall be recorded as follows:  
5.4.1 Make and Model  
5.4.2 Part Number  
5.4.3 Serial Number  
5.4.4 Hardware Revision number (if any)  
5.4.5 Number of drive/steer wheels  
5.4.6 Steering type  
5.4.7 Type: for example, Fork, Tugger, Unit Load, Cart  
5.4.8 Loaded/Unloaded  
5.5 The main A-UGV software parameters shall be recorded as follows:  
5.5.1 All applicable software and firmware versions.  
5.5.2 Velocity – translation and rotation, minimum/maximum.  
5.5.3 Acceleration – translation and rotation, minimum/maximum.  
5.5.4 Stand-off distances – safety sensor thresholds, obstacle avoidance thresholds.  
5.6 The context for the test shall be recorded by providing detailed answers to the following questions:  
5.6.1 When are the various software configurations used during the test? For example, two software versions may be required as follows: Use configuration A for straight aisles and configuration B for turns.  
5.6.2 What other hardware and software parameters/settings are required to recreate the A-UGV behavior (that is, attached debug, settings, or other fi...

SIGNIFICANCE AND USE
4.1 Assuming the vehicle stays on its path and an obstacle appears within the stop zone, the vehicle will collide with the obstacle. Even within the stop zone, obstacle detection should cause the vehicle to slow down as early as possible using non-contact sensing or contact bumpers. ANSI/ITSDF B56.5:2012 discusses a test method to detect standard test pieces beyond the minimum vehicle stopping distance at 50 % and 100 % of vehicle rated speeds.  
4.2 This test method can apply to A-UGVs for testing obstacle-sensing capabilities and automatic guided industrial vehicles in automatic mode of operation in non-restricted areas as described in ANSI/ITSDF B56.5.  
4.3 Researchers2, 3 used two-dimensional (2D) laser detection and ranging (LADAR) sensors mounted to an A-UGV. In contrast to the earlier experiments in which the test piece was static, in these experiments the A-UGV and the test piece were both moving. The 2D sensor was mounted to the A-UGV to scan horizontally with the beam approximately 10 cm (4 in.) above and parallel to the floor and confined to detecting the vehicle path (vehicle width) at the maximum stopping distance (coasting or braking). Note that the sensor scan width can be set to any width, including the ANSI/ITSDF B56.5 standard, non-hazard zone vehicle path width of the vehicle plus 0.5 m (1.6 ft). The test piece entered the A-UGV path within the exception zone, was detected by the safety sensor, and the distance of the test piece to the A-UGV and the A-UGV stopping distance measurements were calculated and analyzed.
SCOPE
1.1 This test method measures an automatic/automated/autonomous-unmanned ground vehicle (A-UGV) kinetic energy reduction when objects appear in the A-UGV path and within the stop-detect range of the vehicle safety sensors in situations in which the desired reaction is for the vehicle to stop as opposed to avoiding the obstacle by traveling on an alternative path. The test method measures the performance of the A-UGV only and does not measure the effect on the stability of loads. This test method describes the use of one test piece as described in ANSI/ITSDF B56.5. Other test pieces from ANSI/ITSDF B56.5 could be used. This test method is intended for use by A-UGV manufacturers, installers, and users. This test method does not substitute for required safety testing under ANSI/ITSDF B56.5 or other normative standards.  
1.2 Performing Location—This test method shall be performed in a testing laboratory or the location where the apparatus and environmental test conditions are implemented. Environmental conditions are recorded as specified in Practice F3218.  
1.3 Units—The values stated in SI units are to be regarded as the standard. The values given in parentheses are not precise mathematical conversion to inch-pound units. They are close approximate equivalents for the purpose of specifying material dimensions or quantities that are readily available to avoid excessive fabrication costs of test apparatuses while maintaining repeatability and reproducibility of the test method results. These values given in parentheses are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 A-UGVs operate in a wide range of applications such as manufacturing facilities and warehouses. Fig. 8 shows three example A-UGV types and test apparatus sizes to test A-UGVs intended for different vehicle tasks, types, sizes, and capabilities. Such sites can have both defined and undefined areas that are structured and unstructured. The testing results of the candidate A-UGV shall describe, in a statistically significant way, the ability of the A-UGV to traverse the commanded path. Whether or not an A-UGV is able to deviate from its path, or uses features of the local environment as input to its navigation method or both, should not result in a different test method. Rather, the capabilities of the A-UGV to adapt its navigation method in a given environment will be objectively determined by its performance in the test method.  
5.2 Three different manners in which a test method can be rendered are specified for use: physical boundaries, virtual boundaries, and floor markings (see Section 6 for apparatus specifics). The test method(s) chosen shall be appropriate to the application and environment in which the A-UGV will be used.  
5.3 These test methods address A-UGV performance requirements expressed by A-UGV manufacturers and potential A-UGV users. The performance data captured by these test methods are indicative of the capabilities of the A-UGV and the application represented by the test.  
5.4 The test apparatuses are scalable to constrain A-UGV sizes in defined areas to meet current and advanced next generation manufacturing and distribution facility operations.  
5.5 The standard apparatuses are specified to be easily fabricated to facilitate self-evaluation by A-UGV developers and users and provide practice tasks for A-UGV developers, users, and potential users that exercise A-UGV actuators, sensors, and controls.  
5.6 Although the test methods were developed first for A-UGVs, they may also be applicable to mobile manipulators and other types of in...
SCOPE
1.1 Purpose:  
1.1.1 The purpose of this test method is to evaluate an A-unmanned ground vehicle’s (A-UGV) capability of traversing through a defined space with limited A-UGV clearance. This test method is intended for use by A-UGV manufacturers, installers, and users. This test method defines a set of generic 2D area shapes representative of user applications and for different A-UGV types.  
1.1.2 A-UGVs shall possess a certain set of navigation capabilities appropriate to A-UGV operations such as A-UGV movement between structures that define the vehicle path. A navigation system is the monitoring and controlling functions of the A-UGV, providing frequent A-UGV updates of vehicle movement from one place to another. A-UGV environments often include various constraints to A-UGV mobility. In this test method, apparatuses, procedures, tasks, and metrics are specified that apply constraints and thereby, standard test methods for determining an A-UGV’s navigation capabilities are defined.  
1.1.3 This test method is scalable to provide a range of dimensions to constrain the A-UGV mobility during task performance.  
1.1.4 A-UGVs shall be able to handle many types of open and defined area complexities with appropriate precision and accuracy to perform a particular task.  
1.1.5 The required mobility capabilities include preprogrammed or autonomous movement or both from a start point to an end point. Further mobility requirements may include: sustained speeds, vehicle reconfiguration to pass through defined spaces, payload, A-UGV movement within constrained volumes, or other vehicle capabilities, or combinations thereof. This test method is designed such that a candidate A-UGV can be evaluated as to whether or not it meets a set of user application requirements.  
1.1.6 Performing Location—This test method shall be performed in a location where the apparatus and environmental test conditions can be fully implemented. Envi...

SIGNIFICANCE AND USE
4.1 Lighting:  
4.1.1 Various lighting conditions can potentially affect A-UGV optical sensor performance by affecting sensor and in turn, A-UGV responsiveness. Lighting sources can include ambient lighting as well as light emitters associated A-UGV operation. Two setups for lighting include direct and indirect source applied to the A-UGV. Direct lighting can also include reflected light from a highly reflective surface and implies that the source is directed at the light-affected components of the A-UGV (for example, sensors). Indirect or ambient light includes lighting where the source is not directly applied to the light-affected components of the A-UGV. Lighting exposure is either continuous light applied to the A-UGV or transitional in which the vehicle passes through various lighting conditions and levels. Light intensity is divided into five levels exemplified through dark, typical indoor lighting, and full sunlight.  
4.1.2 Ambient Lighting Type:  
4.1.2.1 Exposed bulb,
4.1.2.2 Spotlight,
4.1.2.3 Sunlight,
4.1.2.4 Reflected,
4.1.2.5 Light from another vehicle,
4.1.2.6 Laser,
4.1.2.7 Filtered.  
4.1.3 Ambient Lighting Source:  
4.1.3.1 Direct Highly-Concentrated, Directional Lighting,
4.1.3.2 Indirect and Diffused.  
4.1.4 Ambient Lighting Source Location—Record light source location and elevation with respect to the vehicle (refer to Fig. 1).

SCOPE
1.1 This practice describes a means to record the following environmental conditions that may affect the performance of A-UGVs: lighting, external sensor emission, temperature, ground surface, air quality, humidity, and electrical interference.  
1.2 The A-UGV operating ranges for each of the conditions listed in 1.1 are described and parameterized in Section 4 and allow a basis for performance comparison in test methods. The approach is to divide the list of environmental conditions into sub-conditions that represent the various aspects of the major category (for example, sunlight within ambient lighting). Where necessary, this practice also provides guidelines (for example, lighting direction) to record environmental conditions in an existing environment.
