Four types of intelligence, self-knowing, action-planning, target-setting and scope-limiting are essential for the production progress of distributed autonomous production. The fundamental controlling features that differentiate distributed autonomous production control (DIST) and centralized production control (CENT) are the local/global view and concurrent/sequential processing, respectively, in controlling operations. The ability of production control is characterized by response time, planning scope and progressive accuracy. The characteristics of DIST are short response time, narrow planning scope and high progressive accuracy. The experiment of job shop simulation shows that DIST can meet the due time without any capacity planning in advance, and that the real-time response that DIST can realize is essential to achieve short lead-time production. However, in heavy workload production circumstances, the lead-time of CENT is smaller than DIST, because CENT, which has a wide planning scope as a charact...

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.
