The good folks at IAS Laboratory have come up with a robot powered by dead flies:
The main objective of our work is to build energetically autonomous robots. We believe that MFC technology is a good way forward, as the robot will incorporate in its behavioural repertoire actions that involve search and get hold of food and also remain inactive until energy is sufficient to do the next task. This will be a paradigm shift in the way action selection mechanisms have been designed so far.
The SF vision of the future is getting closer every day! I want a servant ‘bot that I can send out to the yard to graze for energy instead of spiking my electric bill. I can’t wait!
