Why stop? Swaying is awesome.

I'm betting that rather than a mechanical gyro, its probably an electronic gyro, and that the swaying is the oscillation around the set point.

It look very stable mostly because i still think that there is a massive gyroscope in the middle. Looks like it has a mechanical gyro not an electrical gyro. The reason its mechanical is because if the robot can oscillate around a given point then it has some force pulling it to its neutral position. If it was strictly an electrical gyro then the robot would have to move its ball to move into position under its center of gravity. Rosie probably has a mechanical gyro to keep it balanced and an electrical gyro to keep it in one spot and return it to that spot if its moved.
