In order to construct three-dimensional shape models of large-scale architectural structures using a laser range finder, a number of range images are normally taken from various viewpoints, and these images are aligned using post-processing procedures such as the ICP algorithm. However, in general, before applying the ICP algorithm, these range images must be registered to roughly correct positions by a human operator in order to converge to precise positions. In addition, range images must be made to sufficiently overlap each other by taking dense images from close viewpoints. On the other hand, if the positions of the laser range finder at viewpoints can be identified pre-cisely, local range images can be directly converted to the global coordinate system through a simple transformation calculation. The present paper proposes a new measurement system for large-scale architectural structures using a group of multiple robots and an on-board laser range finder. Each measurement position is identified by a highly precise positioning technique called Cooperative Positioning System (CPS), which utilizes the characteristics of the multiple-robot system. The proposed system can construct 3D shapes of large-scale architectural structures without any post-processing procedure such as the ICP algorithm or dense range measurements. Measurement experiments in unknown and large indoor/outdoor environments are successfully carried out using the newly developed measurement system consisting of three mobile robots named CPS-V.

Humanoid robot arms have attracted more and more attention since it is human-friendly with the same size and movement characteristics of a human arm. A new 7-DoF (Degrees of Freedom) humanoid robot arm is proposed in this paper. To achieve high torques while keeping down the weight, all the motors are coupled with tendons. 2 motor 2-DoF (2M2D) and 3 motor 3-DoF (3M3D) coupled tendon-driven joint modules are proposed as basic components for the robot arm. The 2M2D coupled tendon-driven joint module and the 3M3D coupled tendon driven joint module structures are analyzed and compared. The 7 DoFs of a human arm were divided into a 3-DoF shoulder joint module, a 2-DoF elbow joint module, and a 2-DoF wrist joint module. The developed robot arm weighed 2.2[kg], while being able to lift a 1.5[kg] load. A current consumption experiment was conducted to verify the torque transmission characteristics of the 2M2D and 3M3D joint modules. A path repeatability experiment and an experiment to imitate dexterous manipulations of a human arm with master-slave control were conducted to investigate the performance of the modularized humanoid robot arm. The experimental results showed that the joint modules realized motor reallocation via tendon coupling, and that the humanoid robot arm was capable of performing dexterous manipulations like a human arm.

We have applied a parametric excitation method to a kneed biped robot with semicircular feet and have shown that the robot can walk sustainably with only knee torque. A swing-leg of the kneed biped robot has similar mechanism to an acrobot, and many acrobots are controlled in inverse direction like ornithoid walking. These suggest that inverse bending of a knee restores more mechanical energy than forward bending, and hence, the ornithoid walking can be more efficient. In this paper, we first compare the forward bending with the inverse bending for a double pendulum, and show by numerical simulation that the mechanical energy of the inverse bending increases more than that of the forward bending like human walking. We then propose a parametric excitation based ornithoid gait for a kneed biped robot, and show sustainably walking by numerical simulation. Finally, we compare parametric excitation based ornithoid gait with parametric excitation based human gait, and we show that ornithoid gait is more efficeint.

This paper proposes the concept of a novel multi-wheel stair-climbing wheelchair. The necessity for mobility aid technology for elderly and handicapped people that has ``minimal invasiveness for use in an historical environment'' are described. With this goal in mind, a prototype of a novel wheelchair having a stair-climbing function resulting from transformable wheeled four-bar linkages is proposed, and the principle of operation, mechanism design, kinematics, statics and basic performance confirmed through a experiment are illustrated in this paper.

With the depletion of global energy resources, saving energy has become an important aspect in design of energy consuming equipment. Hence, this paper deals with an optimal time of operation of a manipulator which minimizes the energy dissipated in the actuators. When the manipulator is operated in a vertical plane, the system is highly non-linear due to gravity and an analytical solution can not be found. Therefore, the system is first linearized around various equilibrium points and the existence of an optimal time is investigated theoretically. The theoretical results resemble the simulation of the non-linear system except for a slight difference in the optimal time. The theoretical results and simulations show that an optimal operating time exists when the first link of the manipulator traverses the stable equilibrium point and that it does not exist when the first link traverses the unstable equilibrium point. Finally, a non-linear optimization method is applied to ascertain the accurate optimal time of operation.

There are many robots which are controlled with PCs (Personal Computers) . Their typical OS (Operating System) was MS-DOS, but MS-DOS is not suitable for high level control. Therefore, RTLinux was developed as realtime OS. However, the authors tried to control mechatronic system by using common Linux and found that it has enough ability to control robots. In this paper, it is described why the common Linux can be used as OS for PCs that control robots. Some experimental results that indicate performance of common Linux as robot controlling OS are also provided. Then the control system developed for human type biped robot as an example that utilize this method is shown.

On the moon, planets and volcanic area, it is difficult for the robots with wheels, crawlers, legs individually equipped to cross over the large rocks, high step and so on. For acquiring high cross-country ability, to pass the terrain with its body and the shape of its moving mechanisms transforming according to the shape of terrain, is effective. We have been researching and developing such a high performance cross-country robot. Here we introduce the concept and overview of the robot and the results of the test of the intermediate pilot model with 4 crawlers on mainly about the cross-country ability based on terramechanics.
