Interestingly, the 2005 Guinness World Records listed the QRIO as the first bipedalrobot capable of running (which it defines as moving while both legs are off the ground at the same time).
The control programs have been used to create control systems for a bipedalrobot and a visual recognition system for a robot that works even when the machine is distracted by flashing lights and shadows.
Those looking to tinker with humanoid robots aren't exactly lacking for options these days, but Cognitive Spring is taking a slightly different approach than most with its Arduino-based cSpring bipedalrobot -- one of the semifinalists in the Insert Coin competition here at Expand.
