Well, apparently this little robot walks with more natural walking gait than the old wind up toys. This robot shifts its weight from one leg to the other as it takes a stride. Here is a video clip of this little guy in action.
As you can see, the robot also swings its arms and moves its head back and forth as it walks. I'm thinking: very hackable! The Cam-10 stands 4 inches tall and uses 1 N size battery (included, thank goodness!). Your choice of "Stealth Black" or "Invisible Clear".
