A test of SpotMini's ability to adjust to disturbances as it opens and walks through a door. A person (not shown) drives the robot up to the door, points the hand at the door handle, then gives the 'GO' command, both at the beginning of the video and again at 42 seconds. The robot proceeds autonomously from these points on, without help from a person. A camera in the hand finds the door handle, cameras on the body determine if the door is open or closed and navigate through the doorway. Software provides locomotion, balance and adjusts behavior when progress gets off track. The ability to tolerate and respond automatically to disturbances like these improves successful operation of the robot. (Note: This testing does not irritate or harm the robot.)
Handle is a research robot that stands 6.5 ft tall, travels at 9 mph and jumps 4 feet vertically. It uses electric power to operate both electric and hydraulic actuators, with a range of about 15 miles on one battery charge. Handle uses many of the same dynamics, balance and mobile manipulation principles found in the quadruped and biped robots we build, but with only about 10 actuated joints, it is significantly less complex. Wheels are efficient on flat surfaces while legs can go almost anywhere: by combining wheels and legs Handle can have the best of both worlds.
