This paper describes a control scheme for the stable operation of a two-wheel driven mobile manipulator. The manipulator has excellent mobility and manipulability, and is capable of many functions. Therefore, it is very effective for use in human environments. However, since the mobile manipulator is unstable, it is difficult to perform specific tasks such as tasks requiring the precise movement of the manipulator and those that need large power, even if its attitude is controlled. Hence, in this paper, landing motion control is proposed to enable the stable operation of the manipulator. In addition, in order to switch from the landing mode to the moving mode, rising motion control is proposed. The validity of the proposed method was confirmed by experimental results.
