Humans have mastered acrobatics for centuries, but robots? They've barely learned how to jump, and Disney Research wants to fix that. It recently developed a human-scale robot, Stickman, that can perform aerial stunts with a grace closer to that of its fleshy counterparts. Much like a person, it tucks into a ball in mid-flight to perform backflips and other stunts. A combination of inertial motion sensing and a trio of laser rangefinders give the robot motion and height data that help it decide when to untuck and land safely.
