災害現場で救助作業を行う, あるいは地雷原でハイパーテザーなどを用いては雷探査を行うことの出来る実用的な移動作業ロボットを開発する要請が高くなっている.この様な目的の実用的な移動作業ロボットには, 不整地環境を自在に移動できる走破性, 長時間走行性能, 作業時にハイパーテザーやマニピュレータなどの作業機器に対して十分なエネルギーを供給できる性能などが必要とされる.そのため, オフロードのバギー車をベースマシンとして利用し, そのアクセルとブレーキ操作をコンピュータ制御して自律的な不整地走破性を実現し, さらにバギー車の原動機を作業機のエネルギー供給機器として転用することで, 実用的な自律走行型バギー車両ロボットを開発した.

It is a well-known fact in morphology that static forms of living organisms are classified into several fundamental shapes. Some of them can be described by a geometrical function. On the contrary, the posture of a moving animal has scarcely been treated in morphology, with a few exceptions. But it seems that the posture could be represented with an idealized mathematical form if the animal's behavior is conditioned and maintained in uniform and stationary surroundings. The present paper shows one such typical case, discussing the shape of a gliding snake.In this paper the gliding shape of snakes during locomotion on a flat surface in stationary straightforward movement is treated. The authors conclude that two kinds of geometrical curves, Eq. (7) and (10), represent sufficiently the shape of a gliding snake. Especially the curve derived under the assumption that the muscle will repeat contraction and relaxation cycles harmoniously during serpentine movement, which we named as the “serpenoid curve”, is shown to be remarkably similar to that of a living snake. Thus the authors believe that research on the shape of animals is useful not only to zoology but also to the biomechanics of an artificial animal-like vehicle and its designing.

A development of stair climbing mobile vehicle to be the base for stair climbing wheelchairs and/or inspection robots is greatly demanded. Several types of the vehicles using crawlers, wheels and legs have been proposed to perform such a stable stair climbing motion. However, conventional vehicles are limited by their mobility, safety, and mechanical size and weight. We propose a new stair climbing leg-wheel hybrid vehicle coined as“Zero Carrier”. The Zero Carrier composed of unified eight prismatic-joint legs, four of which attached active wheels and other four attached passive casters. Proposing Zero Carrier can be designed lightweight and powerful. It can also maintain high stability on stair climbing motion and perform slip-less turning motion. Design of driving mechanisms, sensors, and motion control of the Zero Carrier are then performed and demonstrated its motion by the mechanical model Zero Carrier I.

A biomechanical study on the serpentine locomotion of snakes is presented including both mechanical analysis and its experimental verification with respect to Elaphe quadrivirgata. The mechanical analysis is based on an active linear linkage model, and the theoretical relations of forces induced by antagonistic muscles in straight-forward undulatory movement are obtained. A peculiar mode of snake's movement, which the authors define as the “vertex-lifting locomotion” (as shown Fig. 1), is shown to be optimal for rapid movement. The zoological experiments show good agreement with the theoretical results as well as some assumptions. Thus the authors conclude that this paper will be the first from the biomechanical point of view on snake's locomotion.

The configurational design for a wall-climbing robot which is capable of moving on diversified surfaces of wall and has high payload capability, is discussed, and a developed quadruped wall-climbing robot, NINJA-1, is introduced. NINJA-1 is composed of 1) legs based on a 3D parallel link mechanism capable of producing a powerful driving force for moving on the surface of a wall, 2) a CP (Conduit-wire-driven Parallelogram) mechanism to adjust the posture of the ankles, and 3) a VM (Valve-regulated Multiple) sucker which can provide suction even if there are grooves and small differences in level of the wall. Finally, the data of the trial-manufactured NINJA-1, and the up-to-date status of the walking motion are shown.

In this paper we explain the design of leg-wheeled hybrid jumping robot. First, we developed a light-weight and compact actuator, piston-wire mechanism. Using this mechanism, we achieved the high-speed movement of the leg. Then, the relationship between the jumping height and the motor position is considerd, and the effective design of leg-wheeled mechanism for jumping emerged. In addition, we developed a transmission mechanism inside of the leg frame. Finally, using the light-weight leg-wheeled mechanism, we experiment in wheel drive jumping.

Kinematically redundant manipulators have a number of potential advantages over current manipulator design. For this type of arm, some control methods through pseudoinverse and nullspace of Jacobian matrix had been suggested. Questions associated with them are about the difficulty of real-time control because of voluminous operations for deriving the pseudoinverse matrix by singular value decomposition. In this paper new formulation and control methods for solving redundancy in manipulator arms by locally optimizing a kinematic and/or dynamic criterion are presented. Formulation is performed by means of a joint decomposition technique, resulting in a particularly efficient computational scheme which is feasible for real-time control. Control method based on this formulation is given in low computational cost to compare with conventional control methods.

It is desirable to have a mobile robot which can move and perform various tasks on irregular terrain, but current systems are not reliable or adaptable enough for practical use. A traditional method for climbing stairs is to use knobbed tires or tracks which can grip the edge of the stairs. But with this method usually only one knob on each side of the vehicle grips the stairs because the spacing between the knobs does not necessarily coincide with the distance between steps. In this thesis, a new idea crawler is developed for the stair-climbing. Blocks are attached to the face of the crawler-belt and can change shape to match the edge of the steps. Therefore, a large friction force is obtained by the soft deformation of the blocks at every point along the belt. After experimenting with various types of substances, blocks filled with powder were chosen for their desirable deformation characteristics. The results of this stair-climbing experiment prove that this crawler has better reliability than other crawlers when ascending and descending stairs. Also, this crawler can change its posture when climbing stairs or obstacles and this is also used to increase the turning efficiency of the crawler.

A biomechanical study of living systems suggests us some interesting mechanisms which enable an organism to carry out specific functions. Among various organisms, the authors deal with the organism having a slender configuration and making active and flexible winding motions with muscles attached along the body. In spite of the simple shape, it performs miscellaneous functions which have never been realized in an artificial mechanism.The authors call this type of organism as Active Cord-Mechanism (abbreviated as ACM) and have been studying its motion, control and other problems associated with an engineering application.The basic locomotive motion of ACM on an even ground has already been realized in a snake-like shape.In this paper, some of the problems to develope this locomotive ACM into a more intelligent machine are discussed.First, the installation of tactile sensors is discussed and the biological principle of lateral inhibition is shown to be useful for controlling the ACM with tactile sensors.Second, the efficient and smooth controlling principle is proposed which the authors call the modified first order data hold.Finally, by the ACM mechanical model with tactile sensors and reconstructed controller, more intelligent locomotive experiments have been made, to demonstrate that the locomotion by detecting the obstacle in labyrinth, or the propulsion by pushing a fixed object have been successfully accomplished.Thus the authors believe that this study solves some of the controlling problems of locomotive ACM to develope as an intelligent machine.

For robot arms, wrist mechanisms are important elements for handling ability. We have proposed a heavy-duty wrist mechanism with a large motion range named, "2-DOF Spherical Parallel (2DSP) mechanism." The 2DSP mechanism is driven by a 2-DOF spherical parallel mechanism and supported by a universal joint located at its center. In this paper, we propose a method to maximize workspace in avoidance of singularities or too small output torque. The test model was developed, and the feasibility of the proposed method was verified.
