It seems like we've seen the BlackBerry PlayBook getting put to all kinds of new uses over the last few weeks, and the latest is one of my favorites thus far. In what looks to be an entrant to the Robot Challenge, this custom creation is actually controlled by a BlackBerry PlayBook. It works over a shared wifi connection in conjunction with a BlackBerry Bold 9900. A camera mounted on the robot sends video to the PlayBook, while an on-screen joystick controls the movements. Very cool stuff here that again shows the possibilities of the PlayBook and the BlackBerry platform. Check out the video above for more.
