TC, ISO/TC 184/SC, that is developing
standards for robots and, specifically,
working group 8 (WG 8) is investigating on the standardization needs for
service robots.
Environmental Impact of
Service Robots
The environmental benefits or drawbacks of using robots instead of human
power to perform everyday tasks are
not clear. As mentioned above, the lack

of standards makes it difficult to compare both situations on a level ground.
Furthermore, factors such as the possibility of freeing people's time so that
they can focus on less mundane and
more meaningful work are not easily
accountable.
Currently, service robots in general
draw power from batteries carried on
the robot, which have a limited charge
capacity and constrain the operational
time of the robot. This problem

presents itself as a challenge for manufacturers to design products that are
more energy efficient to extend battery time. For example, as conventional vacuum cleaner manufacturers
increased the motor power to improve
their cleaning ability, robot vacuum
cleaner manufacturers could not do
so as they would have to increase battery size by losing competitiveness.
