We present design and implementation of a tactile sensor system, sensor suit, that covers the entire body of a robot. The sensor suit is designed to be soft and flexible and to have a large number of sensing regions by using electrically conductive fabric and string. The whole signals from the sensor suit are superimposed on a visual image of the robot. The construction of sensor suit with 160 sensing elements for a full-body humanoid and the experimental results to evaluate electrically conductive fabric and the tactile sensing unit are described.

A modeling method to represent bending/torsional deformation of an electric wire is proposed based on the differential geometry. A twisted wire called a robot cable is used in a prismatic/rotational joint of an industrial robot to transmit signals or electric power. It is composed of a twisted bunch of several strands of many copper wires. The copper wire may be cracked by repeated bending/torsional deformation associated with the movement of a joint and such crack leads to wiring disconnection. To predict the life-cycle of the wires and to prevent such wiring disconnection, it is required to estimate deformation of not only the strands but also the copper wires when the wire is bent/twisted. In this paper, the deformed shape of a wire, which corresponds to a twisted bunch of n strands, is described by 3+2n independent variables and can be derived by minimizing the potential energy of each strand under various constraints. As the relationship between copper wires and their strand is similar with that between strands and their twisted bunch, the deformed shape of each copper wire can be also derived with the same method.

This paper presents a shape transformation control method of a mobile robot with wheel-arms. The proposed method aims at transformation from a four-wheeled mode for high speed mobility to an inverted pendulum mode, which has advantages of high viewing position and small turning radius. The transformation starts with lifting up the wheel-arms to raise the center of gravity of the whole body. From such initial states, the body is lifted up and controlled to the target angle by partial linearization, while returning the arms to the initial angle. Then, the wheels are slowed down by properly changing the target pitch angle of the body. Stability analysis is carried out by taking into account the transient response of the body angle to the target value, which is neglected in existing work. The effectiveness of the proposed method is demonstrated by experiments.

This paper presents an efficient control approach for redundant manipulators using a torque-based formulation. First, the manipulator with redundant degrees of freedom is decomposed into several non-redundant subsystems. Then, each of these subsystems is analyzed for the conditioning of the respective Jacobian matrix, considering the dynamic performance. Thus a set of possible solutions is constructed. Further on, the formulation of the proposed redundancy resolution control is realized using the relation between the joint torque and the given end-effector acceleration (<i>torque-based formulation</i>). The approach is suitable for parallel processing, and real-time dynamic redundancy control of redundant manipulators is possible. Numerical simulations have been performed to show the effectiveness.

This paper discusses the design and the basic characteristic of the mobile robot PMR-1 with the preliminaryannouncement and display function of the forthcoming operation (the direction of motion and the speed of motion) to the people around the robot by drawing a scheduled course on a running surface using light-ray. The laser pointer is used as a light source and the light from the laser pointer is reflected in a mirror. The light-ray is projected on a running surface and a scheduled course is drawn by rotating the reflector around the pan and the tilt axes. The preliminary-announcement and display unit of the developed mobile robot can indicate the operation until 3-second-later preliminarily, so the robot moves drawing the scheduled course from the present to 3-second-later. The experiment on coordination between the preliminary-announcement and the movement has been carried out, and we confirmed the correspondence of the announced course with the robot trajectory both in the case that the movement path is given beforehand and in the case that the robot is operated with manual input from a joystick in real-time. So we have validated the coordination algorithm between the preliminary-announcement and the real movement.

In this research, a Universal map, which can be converted to individual maps for heterogeneous mobile robots, is proposed. A Universal map can be generated using our developed measurement robot, and it is composed of a textured 3D environment model. Therefore, every robot can use a Universal map as a common map, and it is utilized for various localization technologies such as view-based and LRF-based methods. In LRF-based localization, accurate localization is achieved using a specific map, which is generated from a Universal map. In a view-based approach, localization and navigation are achieved using rendered images. The use of a Universal map enables generation of these maps automatically. The effectiveness of this approach is confirmed through experiments.

The rapid advancement of robotics has enabled the robots to serve physical help for elderly people in everyday life. This paper investigates what types of robot elderly the most willing to go shopping with. We investigate the effect into following two factors: conversation and robot-type. Conversation means the no purpose talking which human often do. For robot-type, we prepare humanoid and cart robot. To investigate the effect of these factors, a field experiment was conducted in a real supermarket where 24 elderly participants shopped with robots. The experimental results revealed that they prefer a conversational humanoid as a shopping assistant partner.

We have developed a vocal control method based on forward and inverse model, and new vocal cord mechanism, for anthropomorphic talking robot, Waseda Talker No.7, to produce various kinds of voices. The previous artificial vocal cord model could reproduce human-like vibration, however, the control range of the acoustic parameters are very small. We developed new mechanism could adjust the vocal cords tension effectively and control the glottal opening-closing, to broaden the control range. The control parameters of the vocal cords on WT-7 are vocal cord tension, glottal opening and air pressure, and the acoustic parameters are sound pitch, spectrum tilt and sound pressure. The relations between these parameters are complicated, and hard to modeling. The learning process consists of learning of the NN forward model and learning of the inverse model by using the forward model. In addition, the real-time auditory feedback mechanism is used to reduce the error. By this method, the acoustic parameters could be followed well the target.

The purpose of this paper is to show the realization of passive walking of a biped robot Emu that is composed of 1 body and 2 legs. In the beginning of this paper, we fomulate the problem and analyze the stability of the walking with attitude control of a body. The walking is called “semi-passive walking”. We show, next, a numerical simulation on the semi-passive walking. Finally, we show some experimental results to verify a validity of the semi-passive walking and the analysis.
