Sensory system disorder is the neural process of organizing sensory information, which makes children have problems such as limb incoordination, poor sense of space, poor learning ability and even cognitive and emotional disorders. This is prevalent in groups of children in modern families. Radish robot is a two-legged humanoid robot relying on self-balancing technology. It helps children with sensory system imbalance and cognitive impairment to study in a centralized way, and enables children with sensory system imbalance to obtain more professional sports-assisted diagnosis and treatment. Our team is willing to help more groups of children with cognitive impairment, give them healthy and happy childhood experience and physical and mental development, so as to provide healthy development and healthy growth of young and middle-aged talents for the family, society and the country. The mission of the great rejuvenation of the motherland has always been one of the core values of our team, which guides the work attitude and direction of the team, and is committed to investing energy in the fields advocated by the country to create social values that benefit others and self-interest. As the main focus of the radish robot, exercise is an effective measure and way to prevent and restore sensory system disorders. We hope that the radish robot can simulate human activities according to the treatment needs, accompany and guide children to carry out daily exercise, and at the same time improve the level and quality of family sports education to prevent or assist in the diagnosis and treatment of children's sensory system disorders. Its core functions mainly include the following two aspects: 1. simulation movement: according to the video or real-time action, generate robot action, convenient custom three-dimensional action customization, can map the action learning resources to the real world, convenient for children to learn. Based on the Internet technology, the robot-processing end-acquisition end is coordinated, and functions such as remote companionship can also be realized. 2. motion detection and emotion recognition: through cameras and back-end services, the detection and analysis of children's motion and expression data can be realized. on the one hand, the psychological and emotional conditions of children can be analyzed, on the other hand, real-time correction opinions can be given, and the possibility of dynamic preliminary diagnosis of movement disorders can be carried out. In addition, this function can also integrate some safety early warning systems. When an accident such as a fall is detected, it will alert in time to effectively reduce the damage caused by possible accidents to children.
