From 1970's, legged robots have attracted much attention of many researchers. In spite of this, it has been regarded that dynamically stable walking is very difficult to be tackled for any types of legged robots. For a trot gait for quadruped walking robots, we have proposed "the sway compensation trajectory". This method utilizes a lateral, longitudinal, and vertical motion of a robot body to keep a zero moment point (ZMP) on a diagonal line between support legs. In this paper, we develop the sway compensation trajectory for a biped robot, and show that dynamically stable walking is realized. This method makes it quite easy to design stable ZMP and COG (center of gravity) trajectories, which have been regarded as a very complicated and delicate problem. The effectiveness of the proposed method is verified through computer simulations and walking experiments by a humanoid robot HOAP-1, and YANBO-3.

The Tsukuba Challenge is a proving ground for mobile robots, the task of which is autonomous navigatoin along a predefined path of 1km in outdoor environments. We joined the Tsukuba Challenge and achieved the tasks in 2009 and 2010. This paper focuses on the problem analysis and basic design of our navigation system, and presents the design policy and lessons learned in the experiments. Our system consists of gyro-assisted odometry, a roundly-swinging 3D laser scanner, a fish-eye camera, and a localization method using map matching and a particle filter. The integration of these technologies made our system highly reliable to achieve the task.

We developed a two dimensional operation testbed for an autonomous free-flying space robot such as an orbital maneuvering vehicle. This system is named ASROT (Autonomous space robot operation testbed) . Basically, ASROT consists of a satellite robot, a target, a host computer and a planar base. A host computer is only used for observation and data gathering of the system. A satellite robot is a satellite which can establish various tasks with a manipulator. A satellite is 620mm (W) ×805mm (H) ×620mm (L) . Its weight is 120 kg. This system is floating on a planar base using air bearings, and is able to fly around using thrusters for position control and a control moment gyro for attitude control. A manipulator is a flexible arm and 1.4m long. This paper proposes an operating system which is needed for real time autonomous control. A satellite robot installs hardware systems such as vision systems, board computers, image processing units, and software systems such as algorithms for path planning.

Capturing a target by a space robot in space inevitably causes impact forces on the contact points. This paper focuses on such a short contact period and proposes a new approach to model the contact dynamics. It derives equations to estimate the impulse of the contact forces considering the effects of the joint stiffness represented by the joint servo. Using the derived equations, it is shown that the impulse of the contact forces increases with the joint stiffness regardless of its posture. Numerical simulations and hardware experiments are given to validate the proposed approach.

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, an impedance control system which uses together the inner torque control system with the disturbance observer is proposed for the pneumatic robot manipulator. It is assumed that the generated torque by a pneumatic actuator can be estimated from the pressure signals and the discharge volume. And we define that the disturbance torque includes the friction torque, load change and modeling error. At first in order to improve the control characteristics of pneumatic actuator driven by meter out method, we construct the inner torque control system by feeding back the generated torque. Secondly, to reduce the influence of the defined disturbance torque, we compose the impedance control systems with the disturbance observer which can estimate the defined disturbance torque based on the generated torque, the angular velocity and the reaction torque. In order to realize the robust impedance to the defined disturbance torque, we construct the torque based impedance control system which uses together the inner torque control system with the disturbance observer. The real command to the torque control system is generated from the impedance model and the positioning error. From some experiments, it is verified that the proposed impedance control system is effective to adjust the impedance of pneumatic robot manipulator.

This paper proposes a friction model for friction compensation of harmonic drive gearings. The model is composed of parallel viscoelasto-plastic elements and rate-dependent viscosity. Comparative experiments between the proposed model and the Generalized Maxwell slip (GMS) model have shown that the proposed model is advantageous especially in the region of presliding displacement. This paper also presents parameter identification method for the model.

We report a developed autonomous mobile robot (AMR) in dynamically changing environment. The AMR's behavior controller is based upon a state-transition scheme, which suits for realizing the AMR behavior control according to sensory information. The network of state-transition, however, becomes very large as behaviors become complicated. We divide the network among multiple tasks in order to suppress increase of complexity in single network. The tasks consists of a supervisor task and functional tasks. A supervisor task watches overall statuses and events, and controls functional tasks. Each functional task controls a specified part of the AMR's behavior. We constructed a real AMR system, on which the behavior control method is applied and it demonstrated in a showroom as a greeter robot.

The recent growth of robotic manipulation has resulted in the realization of increasingly complicated tasks, and various kinds of learning-based approaches for planning or control have been proposed. However, learning-based approaches which can be applied to multiple environments are still an active topic of research. In this study, we aim to realize tasks in a wide range of environments by extending conventional learning-based approaches with parameters which describe various dynamics explicitly and implicitly. We applied our proposed method to two state-of-the-art learning-based approaches: deep reinforcement learning and deep model predictive control, and realized two types of non-prehensile manipulation tasks: a cart pole and object pushing, the dynamics of which are difficult to model.

Interview survey is one of the options for investigations with light loads on participants to study how people fall compared with measurements by many sensors. In this paper, we aimed at predicting fall patterns from interview text data. We use k-means clustering method to confirm the validity of the labels attached to the interview data, and also confirmed the validity of the summaries of the interview data by interviewer researchers by focusing on the co-occurrence word analysis. After confirming the validity of the labels and summaries, we construct a naive Bayes model classifiers to classify the fall patterns. The average classification rate was 61.1% for 3 types of falls - falls by an unexpected external force, by losing balance or supports, and by other reasons.
