Mobile robots are widely used in many applications, such as transportation, military domain, searching, guidance, rescue,
hazard detection, and carpet cleaning. Because mobile robots usually carry limited power sources, such as batteries,
energy saving is an important concern. In particular, differential wheeled mobile robots that have two independently
movable wheels are popular because of relatively low mechanical complexity to achieve three-dimensional motion on a
ground. This article presents a new wheeled device with a redundant drive system which consists of three independently
movable actuators and two planetary gears to connect the actuators to two wheels. The proposed system is able to
continue its motion safely when one of the motors breaks down for some causes and also able to operate over a longer
period of time due to energy saving consumption property. Experimental results show that the proposed method is
effective in saving energy approximately by 20.45% for linear motion and 13.05% for circular motion compared to a conventional one
