The objective of this paper is to develop a robot system that can transmit the video taken by the drone to the computer in real time, use YOLO to recognize the image of pedestrians, and enable the ground robot to plan the path to avoid pedestrians. External sensors, such as laser range finders (LRF) and CCD cameras, are often used on mobile robots. As we all know, these sensors are susceptible to occlusion. Therefore, even if the mobile robot avoids the pedestrian in front of it, it is likely to collide with other pedestrians that cannot be detected due to occlusion. In this study, we used a drone to shoot videos at high altitudes, transferred the videos to a computer, used YOLO on the computer to perform image recognition of pedestrians around the robot, and passed the recognition results to ROS, which enabled it to plan a path to avoid pedestrians around it. As a result, showed that the videos shot at high altitudes could effectively identify pedestrians around the robot after being recognized by YOLO. © 2025 IEEE.

The objective of this paper is to identify the stresses placed on the musculoskeletal system when small dogs walk on floors with low friction coefficients. In many households, and small dogs in particular are often kept indoors. According to veterinary experience, it is known that small dogs kept indoors that walk with their lower limbs slipping cause a great deal of stress on the musculoskeletal system, and that the incidence of joint disease in the lower limbs of such small dogs is high. In this study, we measured the body movements of small dogs walking on slippery floors using a three-dimensional motion capture system and force plate system. Furthermore, by inputting these measurements into the musculoskeletal simulation model we have developed to simulate the musculoskeletal system of dogs, we derived the load on the musculoskeletal system of small dogs on slippery and non-slippery floors. As a result, it was identified that walking on a slippery floor causes a strong load on the lower limb muscles of small dogs. © 2025 IEEE.

Reduced-order Modeling of Human Body for Brain Hypothermia Treatment

引用

International Journal of Automation and computing 2016年第2期13卷 159-167页

作者： Jinhua She Hiroshi Hashimoto Min Wu School of Engineering Tokyo University of Technology School of Automation China University of Geosciences Master Program of Innovation for Design & Engineering Advanced Institute of Industrial Technology

Brain hypothermia treatment （BHT） is an active therapy for severe brain injury. It makes the temperature of the brain track a given temperature input curve so as to reduce the risk of tissue damage. BHT requires a brain-temperature control system because of environmental disturbances and changes in the human body. The thermal models of the human body devised so far are usually of a very high order and are not suitable for controlling brain temperature. This paper presents a method of finding a reducedorder thermal model of the human body for use in BHT. It combines minimal realization and balanced realization. Unlike other methods, this method yields a reduced-order model that is based on system theory and that takes the frequency characteristics of human thermal sensation into account. It features high precision in the frequency band for BHT and is suitable for the control of brain temperature.

Development of electric cart for improving walking ability — application of control theory to assistive technology

This paper explains the development of an electric cart that helps the elderly maintain or improve their physical strength. Unlike commercially available ones, it has a pedal unit that provides some exercise for a user in training his lower limbs. An impedance model describes the feeling of pushing the pedals. The largest pedal load is determined based on a pedaling experiment. An H∞ controller is designed for each of the largest pedal load and virtually no load. A control law, which is based on the concept of dynamic parallel distributed compensation, is designed using the rating of perceived exertion of a driver as a criterion to choose a pedal load between the largest and almost zero. Five university students and twelve elderly people participated experiments to verify the system design and the validity of the system.

Method of teaching and inheriting for skill is almost oral. It is not quantitative but qualitative. Quantitative inheriting of skill is difficult. In this paper, after tracking of a subject's skill motion using Microsoft Kinect, a subject's motion is visualized as the curved surface. A curved surface is fitted in the positions of a subject's joint, or the direction of trajectories. Expert and beginner perform swimming and karate motion. After the motions are tracked, the trajectories of joints are transformed to a curved surface. The difference of an action between an expert and a beginner is extracted by investigating curvatures and form on the visualized curved surface. Therefore, we expected that technical skill is transferred easily.

In this paper, a robot hand with two fingers, thumb and index finger, aiming at application to a myoelectric prosthetic hand was built to implement fundamental motions, such as grasping and holding, required in daily life. In order to control each finger of the developed robot hand independently, an identifier which recognizes the finger motions based on the surface EMG using the neural networks was constructed, and recognition rate of the finger motions was examined. Experiment for online finger operation of the built robot hand was carried out using the identifier, and fingers of the robot hand were able to be operated as intended. © 2011 IEEE.

Recently, the development of a versatile robot hand aiming at the application to an artificial arm or a humanoid robot is in demand. In this paper, omni-directional bending mechanism which is called "double-screw- drive mechanism" was applied to a robot hand. The robot hands with two fingers and three fingers were built. For the robot hand with three fingers, each fingertip was controlled so as to track the elliptical orbit and experiment was carried out. The DSD robot hand succeeded in rotating the cap of the PET bottle and removing the cap from the bottle. © 2009 SICE.

In recent years, the demand for service robots is increasing all over the world. Service robots have the purpose to assist living, such as medical treatment, transportation and security, and tend to have the function which move automatically in an environment. When operating such an autonomous mobile robot in a real world, the obstacle avoidance is the necessary technique to use a robot safely. A robot has to avoid static obstacles such as garden plants or signboards, and dynamic one such as pedestrians, and especially the robot has to act with caution to pedestrians. The purpose of this paper is analysis of human walking characteristics from the movement of a pedestrian, and from the experimental result, it turned out that the future movement of a pedestrian will be able to predict by movements of a few pedestrians. © 2014 IEEE.
