Scientists at the university of Bristol and the university of the West England built a new system that see will future robots run on urine as fuel. To accomplish their mission, they built an artificial heart which will pump urine, turning waste from live microorganisms as source of electricity to power the robot.
The scientists revealed that they have been working on the project for 10 years now. They have also developed four robots which functions in the same way.
The robot system, as I said earlier, works like the human heart. When heated with an electric, the team explained that the artificial muscle compresses a soft region in the centre of the heart-pump, causing the fluid to be ejected via an opening and delivered fluid to the robot fuel cells.
