In this paper, we show a high power prototype biped robot for application of nursing or running or jumping motions. Light and powerful actuators are required to realize the high-power performance. We propose a method to bring out maximum performance of electric motors aggressively. The technique of motor core temperature estimation and control improves the motor power performance dramatically but safely without motor burnout. High power acctuator system and robust interbody network are depeloped for high power robot. Fundamental demonstrations of high power motion are shown.

This paper proposes a method for training deep convolutional neural networks (DCNNs) as a detector of plant stems partly hidden by leaves. The detector is assumed to be used by an agricultural robot that treats near trees in dense fruit vegitable fields, where the stems of trees are hidden not only by leaves, but also by the totally green confusing background. We tackle this difficult problem by training DCNNs with datasets that are compose of realistic computer graphic images (CG images) and annotated images of foreground leaves and stems. Physically-based Rendering (PBR) and Image-based Learning (IBL) are utilized for creating the CG images that make DCNNs distinguish foreground trees from the background. We have trained two DCNNs with the CG images and created a main stem detector with the DCNNs. In the experiments, the detector has distinguished near trees from the confusing background and has found a main stem partly hidden by leaves.

In Fukushima Daiichi nuclear power plant in which the accident occurred by the East Japan Earthquake in 2011, in order to avoid radioactive exposure of workers, many robots are used. However, it seems that the nuclear peculiarity and the singularity of Fukushima obstruct ordinary robot technicians' entry. In order to make these barriers low, we explain how the nuclear power plant company is designing the robot, and argue also about the difficulty of mechatronics.

This paper presents a walking control system for biped robots on loose soil. The proposed method realizes long time continuous walking and stable stopping on sand. Characteristics of the proposed system is landing position (modification) control. In this control, as a balance index, amount of CoM position modification is utilized. Considering past modification history, amount of current landing position modification is decided. In oder to evaluate the proposed control system, the small humanoid robot performed walking, stepping and turning on sand.

Early human motor development has the nature of spontaneous exploration and boot-strap learning, leading to open-ended acquisition of versatile flexible motor skills. Since dexterous motor skills often exploit body-environment dynamics, we formulate the developmental principle as the spontaneous exploration of consistent dynamical patterns of the neural-body-environment system. We propose that partially ordered dynamical patterns emergent from chaotic oscillators coupled through embodiment serve as the core driving mechanism of such exploration. A model of neuro-musculo-skeletal system is constructed capturing essential features of biological systems. It consists of a skeleton, muscles, spindles, tendon organs, spinal circuits, medullar circuits, and a basic cortical model. Models of self-organizing cortical areas for primary somatosensory and motor areas are introduced. A human infant model is constructed and put through preliminary experiments. Some meaningful motor behavior emerged including rolling over and crawling-like motion. The results show the possibility that a rich variety of meaningful behavior can be discovered and acquired by the neural-body dynamics without pre-defined coordinated control circuits.

In this paper we describe a continuous development and evaluation of multi purpose platform robot AERO via robot competitions. We participated to 4 robot competitions requiring different task with human size semi humanoid robot AERO, has same basic structure. For many types of competition tasks, the robot was designed as simple, robust, small and lightweight, furthermore it can be change parts for another situation of task. The versatility of the robot platform was increased from continuation of task analyisis, consideration of requirements, and implementation. In this paper we describe a continuous integration of robot design, cycle of task analysis, implemetation and integration, via robot competition.

There are many pipes such as a water pipe and a gas pipe in a chemical plant, a factory and house. It is possible to prevent accident ensure safety by these investigating. However, many pipes are very narrow and it is difficult for people to inspect directly. In this study, a cylindrical crawler robot based on Amoeba locomotion, which has a simple mechanism and does not need large space to move, is proposed. When moving the inside of a pipe, this crawler robot uses the elastic force of a crawler belt to hold the robot in pipe. Additionally the robot uses elastic deformation of a crawler belt to pass of a step between pipes with different diameters. Therefore, the robot can move the pipes of different diameters and the perpendicular pipe by using only on actuator. This paper reports the structure, drive mechanism, design, and prototype evaluation.
