4 General Conditions for Testing
4.1 Conditions prior to testing
The robot shall be completely assembled and fully operational in accordance with the
manufacturer’s instructions. All necessary leveling operations, alignment procedures and
functional tests shall be satisfactorily completed.
Prior to conducting any series of tests, the age, condition, and history of the product shall be
recorded.
NOTE: Condition information can include model number/name, software version, and accessories used,
if available.
4.2 Operating and environmental conditions
4.2.1 General
The performance characteristics determined by the related test methods in this Standard are
valid only under the environmental and normal operating conditions as stipulated by the
manufacturer.
4.2.2 Operating conditions
All tests shall be carried out under conditions in which the mobile household robot is operated
in normal use; the normal operating conditions used in the tests shall be in accordance with the
manufacturer’s instructions.
Performance will be affected by the installed software. Therefore installed software shall not
be modified or changed during a set of tests.
4.2.3 Atmospheric conditions
Unless otherwise specified, the test procedures and measurements shall be carried out under the
following atmospheric conditions (in accordance with ISO 554):
Temperature: (20 ± 5) °C
Air pressure: 86 kPa ~ 106 kPa
Temperature and humidity conditions if provided shall be aligned with manufacturer’s
instruction for good repeatability and reproducibility. Care should be taken to avoid changes
during a test.
4.2.4 Lighting conditions
Unless otherwise specified, the test procedures and measurements shall be carried out under the
following lighting conditions:
Intensity: (200 ± 50) lux
Color temperature: 2 000 K ~ 6 000 K
Measurement shall be made at the test surface.
4.3 Test equipment and materials
Measurements on carpets shall be carried out on a level floor consisting of a smooth untreated
laminated pine tree plate or equivalent panel, at least 15 mm thick and of a size appropriate for
the test.
Equipment and materials for measurements (devices, test carpets, test dust etc.) to be used in a
test shall, prior to the test, be kept for at least 16 h at standard atmospheric conditions according
to 4.2.3.
4.4 Number of samples
All measurements of performance shall be carried out on the same sample(s) of the robot with
its attachments, if any.
Tests carried out to simulate stresses a robot may be exposed to during normal use, possibly
causing impairment of the robot performance, may require additional samples of replaceable
parts. Such tests shall be carried out at the end of a test programme.
This mode shall enable the robot to perform a repeatable test mode action in which it shall be
driven forward 1 000 mm and turned 90 degrees 4 times in order to form a single loop. This
test shall be carried out in clockwise and anticlockwise loop as shown in Figure 1. The precise
nature of access to the test mode shall be clearly stated by the manufacturer and it should be
simple to execute. Once the test mode operation is completed it should leave the machine in an
idle state.
NOTE: Examples of access methods to the test mode could be to require the user to have a combination
of buttons on the machine pressed when the robot is switched on, or for a combination of buttons to be
held for a period of time which would not occur during normal robot operation. The only condition is
that this access method is to be documented.
6.3 Test method
The fully charged robot with test mode shall be placed at the starting position as shown in
Figure 1. The body center of robot shall be on top of the starting point, and the robot body shall
be aligned along the direction of travel. Clockwise and anti-clockwise operation commands
shall be given to robot to follow the commanded paths individually as shown in Figure 1.
After the operation has been performed, the deviation (position and orientation) between actual
pose and the commanded pose of the robot shall be measured. A single test for each operation
(clockwise or anticlockwise) consists of three runs.
The floor material used shall be reported in the test report.
NOTE: If the test mode which is to generate the motion required for the test is not readily available in
the robot the test can be skipped.
The average deviation of the position dP for the trial shall be calculated from the three runs,
see Formula (1):
Where:
dPn - is the deviation of position from the nth run, n= 1,2,3
dP - is defined as the distance between body centre and starting position after run.
The average deviation of the orientation dA for the trial shall be calculated from the three runs,
see Formula (2):
Where:
operation time as twork and the chosen operation mode.
The robot shall be fully recharged according to the manufacturer’s instruction. The
corresponding a.c. energy consumption shall be recorded as Ework.
The operation time per single charge is calculated as per Formula (5):
Where:
Tmax - is operation time per single charge;
Emax - is the corresponding a.c. energy consumption for robot from completely discharged to
fully charged;
Ework - is the corresponding a.c. energy consumption for robot from fully charged to completely
discharged after each run;
twork - is the total operation time for each run.
Three runs shall be carried out, and the average shall be considered as the result of the operation
time per single charge.
NOTE 2: This calculation is based on assumption of linear relationships for charging behavior.
NOTE 3: Although this test method is only defined as single test, the tester, may perform more than 1
test.
NOTE 4: Due to tolerances of the measurement if Ework > Emax, then set Tmax = twork.
9 Managing a Single Step
9.1 General
The purpose of the test is to determine the robot’s management of a single step whilst moving
during activities. The mobile robot shall be moving throughout the test time and it is permitted
to restart the robot to encourage movement when terminated because of its function. Other
possible tasks (e.g., air purifying without movement) are not understood as movement and the
time for these tasks are not included to the overall test time.
NOTE: The tester is allowed to restart the robot to encourage movement if necessary.
9.2 Test bed
The test bed is shown as in Figure 4. The test bed consists of the base and the step. The base
Case 2: Robot collides with obstacle
The test shall be terminated if the robot collides with the obstacle.
The maximum force shall be recorded.
The average force of collision with the obstacle shall be calculated as per Formula (7):
Where:
F - is the maximum force of colliding the obstacle after ith collision case;
N - is the number of collisions with the obstacles;
𝐹ത - is the average force of collision with the obstacle.
11 Cable Traversing Behavior
11.1 General
This test measures the impact of the mobile household robot has on a cable when the robot tries
to cross it. By having the cable attached to a pendulum it is possible to measure the pendulum
swinging distance. The swinging distance corresponds to the pulse transferred to the cable.
NOTE: This is a comparative test within a single lab and absolute values may not be repeatable in
different laboratories.
11.2 Test bed
11.2.1 General
The length and width of the test bed shall be at least 2 000 mm × 1 150 mm. Only the obstacle
under test shall be placed in the test bed area. A scale, similar to a dartboard, shall be put on the
floor where there is a free space, in order to ensure that there is no impact from the surroundings
on the product. A carbon fiber pendulum hanging freely from the ceiling with its bottom end
freely movable in its X and Y-axes, with Z defined in the direction of the pendulum, and
coordinate system fixed at the center of the pendulum. The pendulum shall be mounted in such
a way as the bottom edge sits 15 mm above the floor level. Insert an eyelet into the bottom of
the tube through which the wire should be run so that it does not lose contact with the stick as
shown in Figure 8.
The length of the carbon fiber tube shall be 2.5 m ± 0.2 m and 20 mm to 40 mm outside diameter.
It is important that the pendulum is as stiff and lightweight as possible to get a stable and
