This paper proposes a sticking fault detecting method for controlled auto-regressive integrated moving average model (CARIMA) which detect the sticking fault of control input and feedback signal. It consists of model estimation using recursive least square method with the forgetting factor and fault...

From the viewpoint of preventing dementia, balanced meal, moderate exercise, intellectual activities and social interaction are important. We considered shopping activities were proper to encourage those factors because the activities were intellectual in human daily activities. In this paper, we are...

The high-voltage transmission line had been used primarily for power distribution from power plant or power station to the end users. However, the transmission line is highly prone to damage due to exposure to various thermal–mechanical loadings and material degradation. Therefore, periodical inspection...

The conventional wheel is famous in the industrial mobile robot because it is simple to build and easy to control and to maneuver. On the other hand, the legged robot is complicated to control but has a high performance in locomotion like highly evolved legged-creatures. This research describes the four-legged...

This paper proposes a scheme to improve the differential evolution (DE) algorithm performance with integrated the grasshopper optimization algorithm (GOA). The grasshopper optimization algorithm mimics the behavior of grasshopper. The characteristic of grasshoppers is slow movement in the larval stage...

Educational activities with robots have been conducted at each stage – from kindergarten to junior high school. In this paper, we propose and verify educational material supporting collaborative operations through experiences related to people and objects. Specifically, three children used joysticks...

In this paper, we propose the human lumbar burden evaluation method and state estimation system using a smartphone and an application on agricultural work. The proposed system consists of two functions: (1) “State estimation” has a function of estimating posture (Stand up, Sit down, Crouch, Walk, etc.,)...

It is an important problem how to estimate the learning achievement of the programming learning. However, the quantitative evaluation method according to learning achievement is difficult. On the other hand, “work” of a control program influences the control performance of the plant by the petrochemical...

Digital cameras are being widely used in robotics in 3D scene reconstruction, simultaneous localization and mapping (SLAM), and other applications, which often require real-time video stream from multiple cameras. In a case of a mobile robotic system with limited hardware capabilities performance issues...

In this paper, while control engineering replete with mathematical content is difficult for a beginner to learn, it is a practical branch of learning where the control theories expressed by mathematical equations prove useful only after being put into practice. However, the current status of students’...

A shape memory alloy (SMA)-based spring actuated gripper (SAG) was designed and developed for facilitating minimally invasive surgeries (MIS). Specifically the research consists of design and development of a SMA spring which acts as the actuator for the gripper. A novel mechanism was also developed...

In Japan, sports efforts are actively being carried out to host the 2020 Olympic Games. Especially in the field of sports science, researches on ergonomics, development of sports equipment and pattern recognition technology using artificial intelligence are actively researched. In previous research,...

We report on the development of a recipe recommendation system using collaborative filtering and impression words. As a user interface (UI), we adopted MikuMikuDanceAgent (MMDAgent). In our system, the first recommendation process using collaborative filtering is terminated based on the previously decided...

Ability of keeping the tempo is one of the important factors in playing music. In this paper, the authors carry out comparative experiments on the effects of off-line visual and verbal feedback instructions for informing the performance in trying to keep the tempo at 1 Hz by tapping the rhythm. The participants...

The integrated narrative generation system (INGS), that the authors have developed, generates a story to translate the story into the surface representation. In the story generation process, the integrated narrative generation system uses narrative knowledge that was automatically acquired from existing...
