A soccer−machine was developed to adapt a wheelchair for physically handicapped peoples. Reserches were made from three sequential aspects. A basic discussion was made on the energy source of kick action which was resultantly chosen as the sum of the kinetic moment of body and arm power.
　A link action simulator was developed here based on an object language which has clarified the relation of initial link postures and kick velocity. A prototype machine was fabricated using a fricton type energy transmission from wheelchair. By pulling a handle from the initial link position to kick position, the link was accelerated by wheel and arm until the handle were released or turned out to indside - kick position.
