Lego bipedal bot takes several small stairs for man, one big fall for robotkind (video)
Posted in: lego, robot, Robots, Today's Chili, video
Climbing stairs is one of the hardest physical tasks for a bipedal collection of motors and circuits, as Honda’s ASIMO can relate, but one man’s managed to achieve just that with this head-banging Lego Mindstorms NXT robot. After spending years tinkering with the plastic blocks, 222Doc’s X-2 Chicken Walking Biped can autonomously walk up and down flights of small steps with relative ease, perform headstands and even scale five-inch cinder block cliffs if precariously pushed. The robot requires only seven Lego servo motors plus a touch sensor and gyroscope in each foot, but also uses a pair of third-party multiplexers (also spotted in that transforming Wall-E) for fine control of the extra motors. Watch it perform after the break, but stop the second video at 3:20 if pain makes you queasy — the bot takes a pretty ugly spill.
