Research on biomechanics-based design of home-based intelligent elderly care robot

Based on the theoretical knowledge of biomechanics, this paper parameterizes the biological structure of the human body and constructs a human biomechanical model in three dimensions: horizontal dimension, vertical dimension, and torsion dimension, and analyzes in detail the relationship between the stresses in the process of intelligent assistance for nursing robots. Based on the human biomechanical model, the overall design scheme of the home-based intelligent elderly care robot is determined, and corresponding software and hardware are used to realize the design of the home-based intelligent elderly care robot. Select experimental tools and test environments to verify and analyze the biomechanics-based elderly care robot. The error between the theoretical value (software simulation results) and the actual value (equipment test results) of the force of the intelligent assistive process of the nursing robot is kept below 5%. The correct rate of urinary and fecal flushing detection of the home smart elderly care robot is more than 0.95, and the response speed of the control system is controlled within 5 s, while the Central Processing Unit (CPU) occupancy rate is not more than 30.00%, which indicates that the home smart elderly care robot can be effectively used in the elderly care work. The combination of biometrics and information technology is a prominent contribution of this article.
