Weighing a little over 4 pounds, RiSE is a six-legged climbing robot that can trek up and down vertical terrains. It uses a fixed tail for balance on steep ascents.
“Each of RiSE’s six legs is powered by two electric motors. An onboard computer controls leg motion, manages communications, and services a variety of sensors. The sensors include an inertial measurement unit, joint position sensors for each leg, leg strain sensors and foot contact sensors.”
