A low-cost motion platform with balance board

We propose a low-cost motion platform which enables reduces the load to the actuator with a spherical body like a balance board. In our method, by supporting the movable base with a spherical body, most of the load is released to the ground via the fixed base, and the center of gravity of the load is lowered by attaching the spherical support to the movable base. As a result, the moment which increases at the time of rotation of the movable base is reduced, and the load applied to the actuator with no need for the complex control and with simple structure can be greatly reduced.
