An unmanned vehicle is provided that includes a housing configured to rotate about a rotational axis. The housing supports a pendulum drive assembly having coaxial first and second drive axles that are coaxially aligned with the rotational axis. A first rotating member is mechanically coupled to the first drive axle and configured to rotate with the first drive axle. A second rotating member is mechanically coupled to the second drive axle and configured to rotate with the second drive axle. The pendulum drive assembly includes a first electrical motor and corresponding first transmission system that are operably coupled to the first drive axle as well as a second electrical motor and corresponding second transmission system that are operably coupled to the second drive axle. The first electrical motor, the first transmission system, the second electrical motor, and the second transmission system contribute to an effective pendulum mass disposed within the housing that rotates about the rotational axis of the housing relative to the housing and driven by operation of at least one the first electrical motor and second electrical motor to propel the unmanned vehicle.

Pendulum-driven unmanned vehicle

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.
