MechRC Spheroidz: all-surface robot

MechRC introduces its new robot toy, Spheroidz. This strange robot moves inside a transparent plastic bubble allowing it to overcome any obstacle: earth, water, rocks. Spheroidz even goes down stairs (rolling). It is a virtually unbreakable toy, unless someone pierces its bubble of course. But in the future, the protective layer may be hardened (with Teflon), making the robot virtually indestructible. Its price: about 40 dollars. Available soon from RobotShop in the RoboSavvy product category. If we imagine such a robot to human scale in the future, we could have an especially formidable all-terrain machine with particular possibilities for military usage. http://www.youtube.com/watch?v=BfManyeCEuw
