We constructed a spherical pendulum model to represent liquid sloshing in a cylindrical container due to the motions of a wheeled mobile robot (WMR). The model is used to design paths and acceleration patterns for the WMR based on the damping of sloshing. The path curvature radius and WMR acceleration pattern are determined using input shaping. A PD controller enables the WMR to trace the designed path. Maximum sloshing displacement is a constraint condition in control transfer. Simulations and experiments clarified the effectiveness of our method.
