A tracking device includes an external member and an internal member rotatable relative to the external member. A motor is attached to the internal member and includes a rotor shaft attached to the external member. A pair of target sensors that sense a phenomenon such as a magnetic field, sound, light or RF radiation, provide input to a controller that controls rotation of the motor. Angular acceleration of the internal member will cause an equal and opposite angular acceleration of the external member and the tracking device will roll toward the target. The tracking device may hop by suddenly stopping the rotation of the internal member or by suddenly decreasing or increasing the acceleration of the motor or by inserting a linkage fixed to the external member into the rotation path of the internal member.

1. A tracking device, comprising:an external member; an internal member rotatable relative to the external member; a motor attached to the internal member and having a rotor shaft attached to the external member; at least one power source for the motor; a pair of target sensors on the internal member that detect a target; a pair of ground contact sensors on the internal member; and a controller that controls the rotation of the rotor shaft based on signals provided by the target sensors and ground contact sensors.
