A driving roller arrangement of hemisphere is one of the important problems by omnidirectional sphere conveyance. In this research, the roller arrangement problem, viewed as an evaluation function, is thought of as mean of roller’s kinetic energy with respect to the sphere direction. Furthermore, theoretically, we calculate the evaluation function, and find the contact point such that the evaluated value is minimal.
