In these days, planetary explorations attract attention. For the exploration, the spacecraft should land softly and accurately. However, conventional landing mechanisms don't satisfy various needs of landing perfectly. The authors' group proposed Base-Extension Separation Mechanism (BESM) for another mechanism of landing. However, it shoots extra masses not to keep energy in the springs of BESM then, they may pollute the planet surface. Taking such a background into account, the authors propose a novel mechanism called Linear-Rotary-Energy-Conversion Mechanism (LRECM) that exchanges controlled object's kinetic energy for reaction wheels' rotary movement energy by using springs. This paper shows the effectiveness of LRECM by one dimensional simulation and experiment. It can reduce rebound by exchanging the spacecraft's kinetic energy to rotational movement energy and prevent tipping over by rotating reaction wheels.
