Operativity will be spoiled if the thick cable of an end effector is in the exterior of a manipulator. The less wiring device adapting Power Line Communication technology has been developed. Transmission of the information and transfer of power on an end effector are realizable with one pair of twisted pair wires. The technical details, peripheral technology, example of application and future subjects of this device which can be used, such as not only a robot but onboard equipment and plant apparatus, are reported.

In practical use of automatic guided vehicles, magnetic markers are widely used. However, an approach of which pattern of magnetic intensity in usual environment is defined as landmarks is not investigated. This reason is that it is difficult to be known environmental magnetic field since magnetic intensity is invisible. This paper shows investigation of environmental magnetic field in actual environment and describes implementation of the magnetic based navigation, magnetic navigation method. As the magnetic investigation, magnetic intensity of the mounted devices in a mobile robot was measured, and condition of efficient layout of the devices was obtained. By the measurement of environmental magnetic field in mentioned condition, pattern of magnetic intensity that is suitable as a landmark is shown in this paper. The mobile robot records magnetic intensity on its travel path as magnetic map, and achieves stable navigation based on the magnetic map. In this paper, performance of the magnetic navigation method is shown by an experiment.

In order to develop “Active Human Interface (AHI) ” that realizes heart-to-heart communication between intelligent machine and human being, we've been undertaking the investigation of the method for improving the sensitivity or “KANSEI” communication between intelligent machine and human being. This paper deals with the mechanical aspects of “Face Robot” that produces facial expressions in order to express the artificial emotions as similar as human being. As actuators move the face skin of the face robot, we select the flexible microactuator (FMA) driven by air pressure for the sake of moving the control points of the face robot corresponding to Action Unit (AU) s, and we design the aluminium frame of the Face Robot for disposing the FMA and then we make the skull frame onto the aluminium frame. The skin of the face robot made by silicon rubber covers up the skull frame. Then we undertake psychological recognition test by showing the face images of 6 basic facial expressions expressed on the Face Robot, and the results show us that the correct recognition ratio accomplishes 83.3% for 6 basic facial expressions. This high ratio shows the possibility of Face Robot as a “KANSEI” communication medium between intelligent machine and human being.

This paper proposes underwater robots suitable for teaching materials for learning basic mechanics. Recently various robots for teaching materials have been used to educate future engineers. However, the ground based robots are limited due to the size of the contest rules, mechanics are left behind at the workshop. Thus, robots for teaching materials which mechanics have significant influence on solution to the target problem are desired. The authors have focused on underwater robot, because water causes large effect in terms of equilibrium between forces, even to small robots. We developed new teaching materials of underwater robot “Mark1” for junior high school students and held a workshop on a trial basis. We send out questionnaires and evaluated their answers by checklists. As a result, this workshop obtained a large training effect for education of basic mechanics. Then, underwater robot “Mark3” was developed for more advanced students. Mark3 had extensibility and was able to satisfy the needs of students. From the above, It was confirmed that the proposed underwater robots were useful for learning basic mechanics.

As many biomechanists indicate, tendon plays important role for running or jumping motion. It stores the kinetic energy as a potential energy during stance and also absorbs the impulse at touch down. Inspired by such biomechanical studies, we propose a new simple mechanical model for hindlimb of a dog to realize a robot which imitates dog running, and the hardware design of one-legged running robot, "Kenken" The robot has an articulated leg and uses two hydraulic actuators as muscles and a tensile spring as a tendon. Using an empirical controller based on the characteristic dynamics of the model, the robot has succeeded in planar one-legged running. Although the problem related to the stability at the higher running speed remains, the experimental results demonstrate that the proposed leg mechanism is effective for robotic running.

This paper deals with the turning motion mechanism of a brush-type micro robot using cyclic centrifugal forces. Many wheeled type robots may turn usually along the tangential velocity generated by the rolling wheels. However, the micro robot proposed here has different turning property from the usual mobile robots. First, we derive a two dimensional rolling model of the brush-type robot accompanied with cyclic centrifugal forces, and indicate the existence of the lateral force toward the robot by the computer simulations and the simple mathematical analysis. Next, to confirm the turning motion mechanism caused by the lateral force, we have experiments of the turning motion using some kinds of prototype, and then acquire some experimental data concerned with circle trajectories. Finally, we conclude the validity of the turning motion mechanism caused by the lateral forces which the cyclic centrifugal force generates.

International Space Station and other building project in the lower orbit rises the demand of EVA(extra vehicular activity), and due to this, the robots that helps EVA is highly expected. In this paper, we clear the development and designing requests of EVA Supporting Robot and its dexterous hand. The dexterous hand used in the EVA must be small enough to use EVA tools, able to output high grasping power and modularized so that the hand can be exchanged depending on the mission. Following to the requests, we designed a test model of dexterous hand. In this paper, new index robot finger for our dexterous hand is introduced. The finger consists of 1 actuator and 1 passive joint. The architecture and features of this finger are shown in the last half of this paper.

The main purpose of this research is to study and develop a robust sonar system for mobile robots. In this way, some researchers have made sonar systems which calculate the cross-correlation between the transmitted signal and the received one. However, as the number of patterns of transmitted signals are practically limited, there would be possible erroneous measurements by sonar sensors, especially when the number of the sensors is increased.In this paper, we theoretically estimate the probability of erroneous measurement by the sonar sensors, which depends on the number of the sensors and the form of the transmitted signal. Then, we designed the shape of the emitted signals so that the probability of having an erroneous measurement is in a defined range.

A conceptional idea of the pseudo mechanism is proposed. This concept means that a different mechanical feature from the natural one appears on the mechanism by means of control method. For example, a worm gear behaves like an one-way clutch. Generally, worm gears cannot be driven by load torque because of its mechanical stop feature. But the worm gear of this concept can be driven by load in specified direction, and the rotation to the other direction is prohibited. This asymmetrical motion is achieved by a switching operation of a force feedback control. The applied load torque is detected and fed back positively to a position servo control system in order to achieve power assist control. The worm gear seems to be driven by the load torque and it resembles to a spring motion. If the force feedback line is cut off, the drive system cannot be driven by a load. The switching operation of the force feedback line causes to a selection of back drivable feature or mechanical stop feature. The switching condition is set by a direction and threshold value according to the required mechanical feature. The pseudo mechanical worm gear also pretends as a torque limiter or a ratchet.
