RoboMaster Robotics Competition is an international robotics competition, which is held in Shenzhen every year. Engineers studying all over the world design their robots and compete in the game field with each other. This competition is also famous for entertainment. In this paper, we compare cultures between RoboMaster and robocon, a traditional robotics competition. In addition, we describe several technical aspects on our robots and the meaning that engineering students join in this competition.

Atmosphere estimation system for family-type robot in living space is proposed to realize smart symbiotic space, where a three-dimensional atmosphere (atomosfield) is calculated based on multiple human emotions recognized from webcam video. The system is implemented with OpenCV and Dlib for face and emotion recognition, and tested for webcam arrangement. As a result of the experiment for thee human and two LOVOTs interaction in the living space, the proposed system has shown the highest detection of times of 380 at the level of 0.45[m] from the floor and the front (0 deg) of the users in face recognition. The proposed atmosphere estimation realizes casual and delicate support service for people in smart living environment.

Marine debris causes deleterious effects on the environment and economy. It is still a difficult task to efficiently collect marine debris floating on the sea surface. We previously proposed a semi-automatic collection system of marine debris using an underwater robot. However, the success rate is low due to the complicated operations required to collect marine debris. In this research, we propose to use a suction mechanism to simplify the operation of collecting marine debris that enables the underwater robot to collect just by approaching it. The experiments verify the effectiveness of the proposed system with respect to the success rate and time of collection.

Various researches are conducted to reduce the influence of winds and waves for safer work environment on offshore operations and to negate the tilt due to acceleration of vehicle for improved comfortableness. Conventional researches have adopted active mechanism like six-degree-of-freedom parallel mechanism that absorbs the sway by constantly keeping its motion base horizontal to suppress such influences. However, current swing machines require vast areas to be installed since their swing mechanisms are large and their bottom structures are thick. Here, we propose a new swing mechanism “Omni-Swing” which is relatively thin and can be applied to curved surfaces. The mechanism is embodied to a real machine and experiments are conducted to verify its basic characteristic in this paper.

In recent years, the demand for orthodontic treatment has been increasing, but the change in the moment due to the movement of the teeth during orthodontic treatment has not been measured and has not been quantitatively evaluated. The purpose of this study is to develop a three-tooth device with a built-in 6-axis force sensor and to evaluate orthodontic treatment quantitatively. We have developed a device that can change the angle of the central tooth using a stepping motor to reproduce the movement of the teeth during orthodontic treatment. We verified whether wires needed to be reattached during orthodontic treatment using this device. As a result, it turned out that a larger moment can be applied to the teeth by reattaching the wire during orthodontic treatment

This study shows the possibility of plaque detection by near-infrared hyper spectrum imaging (NIR-HSI) and machine learning without plaque stain. While the plaque stain shows where the plaque is, the plaque stain leaves color and may cause anaphylaxis. Near-infrared images are obtained from the plaque cultured teeth by NIR-HSI. RGB images of stained teeth are obtained and superimposed on the near-infrared image. The G channel of the RGB image is corrected to label the spectral data plaque or no plaque. Learning and prediction were performed by Artificial Neural Network. The proposed method showed that plaque could be detected without staining about 70% accurate.
