The purpose of this research was to make a machine or a robot jump over a big obstacle or a ditch. They sometimes need to jump to move over these obstacles. We plan to do fundamental researches on a jumping machine 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 in two dimensional space is described. The optimum soft landing of the jumping machine in two dimensional space is defined. This definition prevents the jumping machine from falling and receiving the big force from the ground. We apply this test to the jumping machine when it jumps and lands in two dimensional space and test the validity of the soft landing by experiment.
