The radial rectilinear stretching motion is firstly analysed, and its condition is deduced. Then two planetary gear mechanisms are assembled to realize the motion. In addition, the kinematics and dynamics analysis of arm mechanism is done, which provide the theoretic basis for the selection of servomotor and for holding the good dynamics and static performance of the clean robot.
