Landing control for a jumping machine

The purpose of this research was to make a jumping machine jump over a big obstacle or a ditch. We plan to do fundamental research to (1) make the jumping machine jump as high as possible, (2) control the direction of the jumping, (3) control the attitude of the machine in the air, and (4) make it land softly. In this paper the method of making the jumping machine land softly is described. The optimum soft landing of the jumping machine is defined as follows: • First, the impulse which the jumping machine receives from the ground should be minimized. • Second, the maximum force which it receives from the ground should be minimized. We apply this test to the jumping machine when it lands and test the validity of the soft landing by experiment.
