Abstract

A robotic ball device having a center point and an axis of rotation passing through the center point around which the robotic ball device rotates during motion in a forward linear direction includes a housing and a defined pathway located on an inner face of the housing that forms a closed loop around the axis of rotation. A rolling member is contained in the housing and movably disposed on the defined pathway. An actuator is coupled to the rolling member for actuating rotation of the rolling member. A weighted component is operationally coupled to the rolling member, and the weighted component is sufficiently heavy to maintain the rolling member, during a motion in the forward linear direction, at a substantially constant angular position in a forward vertical plane, which dissects the rolling member, relative to an origin in a moving frame of reference that moves with the robotic ball device.
