Powercast: Wireless power for robots and devices

Powercast exhibited their power transmission technologies by “shooting” LEDs with energy and making them light up. These guys make the CES rounds so we’ve seen them before but their plan here is to embed their technology into wireless robots and simply send the power along with the control commands as the robots traverse scary terrain.

So far they can replace a set of 4 AAA batteries, depending on the situation and implementation.
