Freely rotating body around its center of gravity can be maneuvered by using a single rotor with the rotating around the axis fixed to the body if the initial angular momentum is not zero. The previous work has shown that the strong accessibility holds almost everywhere in the configuration space. These results are based on local geometric property of the system, namely, the rank condition, and therefore provide no quantitative information about practical maneuverability. This paper visualizes the actual time evolution of reachable set using some sinusoidal inputs.
