A robotic ball that is capable of shifting it's center of mass depending upon human touch.

The Bumble-Bot is designed to nestle comfortably within the human hand or to misbehave and throw a tantrum, as it's mood dictates.

A 3D printed chassis houses two servos that control the position of tungsten weights within the ball: Shifting the weight of the Bumble-Bot.
