RiSE is a small six-legged robot that climbs vertical terrain such as walls, trees and fences. RiSE's feet have claws, micro-claws or sticky material, depending on the climbing surface. RiSE changes posture to conform to the curvature of the climbing surface and a fixed tail helps RiSE balance on steep ascents. RiSE is about 0.25 m long, weighs 2 kg, and travels 0.3 m/s. 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. Future versions of RiSE will use dry adhesion to climb sheer vertical surfaces such as glass and metal. RiSE is being developed in conjunction with researchers at University of Pennsylvania, Carnegie Mellon, Berkeley, Stanford, and Lewis and Clark University. RiSE is funded by the DARPA Defense Sciences Office.
