Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Introduction
This document defines characteristics for the manipulation performance of service robots and
describes how to specify and test them. It is intended that the reader of this document selects which
performance characteristics to test, in accordance with the specific requirements.
The performance criteria specified in this document are not intended to be interpreted as the
verification or validation of safety requirements. The verification and validation of safety requirements
are specified in safety related standards developed by ISO/TC 299.
Tests for position and path accuracy of manipulators, which can be useful in addition to the tests
specified in this document, are provided in ISO 9283.
Tests for locomotion of mobile robots, such as rated speed and stopping characteristics are provided
in ISO 18646-1. Tests for pose accuracy and pose repeatability for mobile robots are also provided in
ISO 18646-2.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 18646-3:2021(E)
Robotics — Performance criteria and related test methods
for service robots —
Part 3:
Manipulation
1 Scope
This document describes methods of specifying and evaluating the manipulation performance of
service robots, notably:
— grasp size;
— grasp strength;
— grasp slip resistance;
— opening a hinged door; and
— opening a sliding door.
There are other grasping characteristics and use cases for manipulation of service robots. It is expected
that these will be included in a future revision.
This document deals with the indoor environment only. However, the depicted tests also can be
applicable for robots operating in outdoor environments.
This document is not applicable for the verification or validation of safety requirements.

3.1
robot
programmed actuated mechanism with a degree of autonomy to perform locomotion, manipulation or
positioning
Note 1 to entry: A robot includes the control system.
EXAMPLE Manipulator, mobile platform, and wearable robot.

[SOURCE: ISO 8373:2012, 2.6, modified — The phrase “actuated mechanism programmable in two
or more axes” is replaced with “programmed actuated mechanism”, the phrase “moving within its
environment, to perform intended tasks” is replaced with “to perform locomotion, manipulation or
positioning”, note 1 to entry is modified, note 2 is removed, and EXAMPLES are added]
3.2
service robot
robot that performs useful tasks for humans or equipment excluding industrial automation applications
Note 1 to entry: Industrial automation applications include, but are not limited to, manufacturing, inspection,
packaging, and assembly.
Note 2 to entry: While articulated robots used in production lines are industrial robots, similar articulated robots
used for serving food are service robots.
[SOURCE: ISO 8373:2012, 2.10]
3.3
mobile platform
assembly of all components of the mobile robot which enables locomotion
Note 1 to entry: A mobile platform can include a chassis which can be used to support a load.
Note 2 to entry: Because of possible confusion with the term “base”, it is advisable not to use the term “mobile
base” to describe a mobile platform.
[SOURCE: ISO 8373:2012, 3.18]
3.4
manipulator
mechanism usually consisting of a series of segments, connected to one another by joints, for the
purpose of grasping and/or moving objects usually in several degrees of freedom
Note 1 to entry: A manipulator does not include an end-effector.
[SOURCE: ISO 8373:2012, 2.1, modified — The phrase “machine in which the mechanism usually
consists of” is replaced with “mechanism usually consisting of”, the phrase “jointed or sliding relative
to one another” is replaced with “connected to one another by joints”, the phrase “(pieces or tools)” is
removed, and note 1 is removed]

end effector
device specifically designed for attachment to the mechanical interface to enable the robot to perform
its task
EXAMPLE Gripper, nut runner, welding gun, spray gun.

gripper
end effector designed for seizing and holding

4.1 General
The service robot, hereafter referred to as robot, shall be completely assembled, configured with
a mobile platform, if applicable, a manipulator and a gripper, sufficiently charged and operational. If
there are any diagnostic tests that have to be performed before the normal operation, they shall be
satisfactorily completed. Appropriate precautions should be taken to protect the personnel during the
test. The tests shall be preceded by the preparations for operation as specified by the manufacturer.
All performance shall be measured under normal operating conditions and these conditions shall be
included in the test report.
All sensors used in the test specified in this document shall be calibrated prior to performing any tests.
The robot may use any sensors and recognition means to identify the object for each test, as long as
they are reported in the test report.
All conditions specified in this clause should be satisfied for the tests described in this document, unless
it is stated otherwise in the specific subclauses.
