Abstract
A ball robot formed from a spherical shell includes a main axle, first and second pendulums pivotally coupled to the main axle, and a drive mechanism for the first and the second pendulums. The drive mechanism drives the first and second pendulums together in a first rotational direction to move the ball robot forward and backward and in opposing directions to cause the ball robot to turn right or left. In an alternative embodiment, a flywheel is used to provide forward and backward movement and a pendulums is used to cause the ball robot to turn right or left.
Claims1
A ball robot, comprising:
- a spherical shell;
- a main axle within the spherical shell;
- a flywheel and associated flywheel drive motor within the spherical shell, the flywheel drive motor configured to rotate the flywheel in a first direction to cause the ball robot to move forward and to rotate the flywheel in a second direction opposite the first direction to cause the ball robot to move backward;
- a pendulum pivotally coupled to the main axle;
- and
- a drive mechanism for driving the pendulum comprising a drive motor configured to move the pendulum in a third direction perpendicular from the first and second directions to cause the ball robot to turn towards the third direction, and to move the pendulum in a fourth direction opposite the third direction to cause the ball robot to turn towards the fourth direction.
