Abstract
The development of highly accurate landing technology is required for the next generation lunar-planetary exploration lander to touch down on rough but interesting area. For the safe landing, the development of landing leg is required to prevent overturning and reduce landing impact of the lander in the final phase of landing sequence. However, it is difficult to design a landing leg which is applicable to a wide variety of terrain. The active landing leg is proposed as a solution of solving this problem. This paper presents the simulation of the lander with active landing leg and development of experimental system using Magneto-Rheological damper, and examines the landing shock response and penetration of the lander leg to the sand terrain.
