In this note, we consider a control system that underlies in a biological system. We point out the existence of the Problem of Inseparability in the control system. To understand the principle of mobile adaptability embedded in the control system, we have to solve the Problem of Indivisibility. To solve the problem, we propose a concept of Implicit control law. Finally, we show the Implicit control law plays an important role for constructing the adaptive function of living thing and robot.

<p>The trap-jaw ant genus <i>Odontomachus</i> closes her mandible to catch prey quite quickly. The purpose of this study is to examine the mechanism how such a fast movement is realized. Since the velocity of closing exceeds the contraction velocity of a muscle, it is considered that there will be a mechanism to store energy and release it at once for realization of high-speed motion in the exoskeleton. We prepare a scale model of Odontomachus with micro CT scanning their exoskeleton data and 3D printer. Using model, we find three regions of contact points of the temporomandibular joint and the exoskeletal part meshes with each other at one of the regions. This structure is considered to be related to a lock mechanism for fast movement of Odontomachus.</p>

これまでの受動的動歩行の研究では,二脚のロボットが対象とされてきたが,四脚以上の脚を持つ生物は非常に多く存在しており,それら生物の歩容と受動的動歩行との関連性を明らかにすることは非常に興味深いと考えられる.そこで本研究では,多脚(4脚あるいはそれ以上の脚)を持つ受動的動歩行を対象に,その実現可能性や多脚受動的動歩行ロボットが示す様々な歩容についての考察を行う.

A passive dynamic walking robot can walk down a gentle slope naturally without any actuator or controller, only by potential energy. Therefore, it is thought that the principle of walking exists in this phenomenon. By current researches, the passive dynamic walking has been confirmed for two and four. However, it seems that it is also important to study passive dynamic walking for more than 6 legs because there are many creatures that have more than 6 legs. In this research, a passive dynamic walking robot with more than six legs was analyzed by a simulator. As a result, it was confirmed that passive dynamic walking even for 20 legs could be achieved. Furthermore, its gait could be changed by changing the body structure. In addition, the differences of stability depend on the number of legs resulted, and this differences disappeared by changing the position of the pitch spin parts. Moreover, its stability was very high, so it could walk on the contoured ground.

In this paper, we discuss some phenomena of obstacle clustering by distributed autonomous robots, in the light of space-discretization (or cellular automata) approach. This work was motivated by Swiss Robots which collect scattered obstacles into some clusters without any global information nor intelligent concentrated controller. Then we define fundamental event rules in this cellular world, and introduce two types of local rules for robot action: one is the Push & Turn rule, which can collect obstacles, the other is Pull & Turn rule, which can scatter obstacles. By defining several indices (ratio of immobile obstacles, ratio of moved obstacles), we investigate the dynamic equilibrium of obstacle clustering by heterogeneous agents. And, this paper also presents a control method of ratio of immobile obstacles from the estimation of each robot's local information even if all the states of obstacles cannot be measured.
