You can see a demo of Sphero™ at Plutopia 2011: The Future of Play, 6:30PM March 14 during SXSW Interactive.
If you look up videos online of humanoid robots, they fall over a lot….We really like the sphere because it’s so simple. It’s one of the most basic shapes, and one of the most basic toys, gaming devices. It’s such a simple shape, but the electronics and firmware inside to control it is actually insanely difficult… but it’s awesome that a ball can’t fall over, that makes it nice mechanically. So very simple, yet mechanically complex.
