Matsushita's already given us a robotic suit to aid in rehabilitation, but it's now taking its robo-upgrades even further, busting out a pair of "Power Pedal" robotic legs to give us humans a fighting chance in the inevitable robot uprising... and help disabled and elderly people walk again. Supposedly, the Power Pedals will give you seven times more strength, and be able to maneuver through difficult terrain without tipping over, thanks to their six directions of movement. Matsushita thinks that'll also make the legs particularly well-suited for use in disaster areas, which would seem to be a likely first test bed, given that they'll cost a cool 20 million yen ($167k) when they're available in August. According to Matsushita, however, that'll come down to just $30,000 by 2015, so start saving up.
