The more catchy title at Hack-a-Day was "robot will hand you your ass at beer pong." That said this video is worth watching. Think of it like a positioning arm for spherical (ping pong ball, orange, onion) or ellipsoid shapes (water bottle). The device maneuvers objects through mazes and can handle stacked objects (two spheres in the same column of air).
