Abstract
An omnidirectional vehicle includes a body, and a plurality of units, each unit including a bearing rotatably supporting a steering shaft around a vertical axis with a rotor plate, and a driving wheel axially supported by a supporter fixed to the rotor plate. The driving wheel is positioned at a location spaced apart for a first offset distance from the steering shaft in the rolling direction of the driving wheel and spaced apart for a second offset distance from the steering shaft in the direction perpendicular to the rolling direction of the driving wheel. A first motor is fixed to the body for driving the steering shaft, and a second motor is fixed to the body for rotating the driving wheel. In the holonomic omnidirectional vehicle, the control system and the driving system are simplified, and interference therebetween is prevented. Also, it is possible to reduce the capacities of the actuators, the electric power for driving the vehicle and the manufacturing costs.
