The U.S. Naval Research Laboratory yesterday gave details of a project to design a "microrover" robot that would be able to explore planetary bodies for long periods of time without human intervention.
To overcome the limitations of today's batteries, researchers intend to use a microbial fuel cell to generate power for a small robot that would weigh about two pounds.
The idea is to have an advanced microbial fuel cell that would generate enough power to maintain the electronics on the robot and charge up a battery or capacitor. Once charged up, the robot would be able to perform more power-intensive tasks, such as moving the rover with a hopping or tumbling motion or run scientific experiments.
