Though we've certainly seen robotic legs that like to get their jump on, a team of researchers at the University of Tokyo have assembled a new two-legged creature that can actually spring up about 50-centimeters on its own -- and land gracefully. The creation is part of a larger project aimed at creating humanoids with cat-like (or just human-like, really) reflexes that can better assist the elderly when used as caregivers. Moreover, this hopper relies on air-driven artificial muscles rather than electric motors, and while we're not sure it could hang with Ronaldinho, it can boot a fútbol when asked.
