(GIST OF SCIENCE REPORTER) MilliMobile — tiny, self-driving robot powered only by light and radio waves

(JULY-2024)

MilliMobile is a small self-driving robot that relies on onboard sensors and computing chips to navigate. Researchers at the University of Washington have developed this tiny robot that can be powered by surrounding light or radio waves.
The newly developed robot has a solar panel-like energy harvester and four wheels, weighs very light as much as a raisin, and is about the size of a penny.
The tiny robot is capable of moving up to 30 feet (10 meters) in an hour, even on a cloudy day and on various surfaces like concrete or packed soil. This also carries a camera or sensors, which is nearly three times its weight.
