Battery-Free Autonomous Robot Can Operate on Harvested Solar and RF Power

Watch this video to learn more about MilliMobile: A battery-free autonomous robot capable of operating on harvested solar and RF power. MilliMobile is the size of a penny and can steer itself, sense its environment, and communicate wirelessly using energy harvested from light and radio waves.

“We took inspiration from ‘intermittent computing,’ which breaks complex programs into small steps, so a device with very limited power can work incrementally, as energy is available,” said co-lead author Kyle Johnson , a UW doctoral student in the Paul G. Allen School of Computer Science & Engineering.
