Certain limitations and challenges are encountered when consider-

ing the application of renewable energy in robotics. Power requirement

of industrial as well as space robotic systems is quite large and can momentarily exceed to MW ranges during continuous operation. In case of service robots, long duration operation maybe required during day/night thus requir- ing a storage system for continuous power supply. Given that a mobile robot has to carry its power source, higher energy density per m2

is another limitation. Another bottleneck is the generating cost of renew-

able energy. However, as predicted by a research conducted by IEA, it

is expected that in the next 30 years, this cost will be reduced

considerably.

No. The cells will be rapidly degraded by solar and other cosmic radiation. Only crystalline cells will withstand this environment.

This is one area where multijunction cells will work well - constant irradiation, constant spectral power density and very high efficiency and cost not a major obstacle.

Thank you, Tony.

And whether it was impossible to economize on weight, considering that the planned service life did not exceed 3 months?
