The robot itself uses a process called Microbial Electrolysis, which is a proven process that uses bacteria as a power source. The robot vacuums up waste, then harnesses the energy within the bacteria to power itself. So in short, the robot is completely sustainable by utilizing power derived from the matter it “consumes” or vacuums up.
Another unique feature of the robot is the honeycomb flex wheels that give the robot the ability to climb up and down stairs and over obstacles. The honeycomb structure is one of the strongest in nature, but when there is pressure, it has the ability to collapse and flex to help guide the robot up stairs.
