The purpose of this research is to make a jumping machine jump over a big obstacle and a ditch. Therefore, the authors plan to do fundamental researches to (1) make jumping machine jump as highly as possible, (2) control the direction of the jumping, (3) control the attitude of it in the air and (4) make it land softly.
In this paper the way to make the jumping machine land softly is described. The optimum softlanding of the jumping machine is defined as follows:
•First, the impulse which a jumping machine receives from outside is minimized.
•Secondly, the maximum of the force which the jumping machine receives from outside is minizized.
When the jumping machine lands, we apply this definition to the body and the leg of the jumping machine. Then the validity of the softlanding is proved by the experiments usining the jumping machine.
