In order to analyze the kinematic parameters of the lower-limb joints of the human body during the sit-to-stand motion assisted by a standing-up robot, based on the analysis of the sit-to-stand process of the human body, a kinematic equation for the sit-to-stand motion of the human body was derived by use of the Lagrangian equation and Hamilton principle, and a simulation platform was established in Matlab/Simulink. The simulation and experi-ment were carried out for researching the change of the joint angle during the sit-to-stand motion when a standing-up robot assisted a patient with the sit-to-stand motion. The results show that the joint angle may be effectively predic-ted by utilizing the established model. In addition, the motion trajectory and the kinematic parameters of the joints of the patient were tested when a robot assisted the patient with the sit-to-stand motion, so as to lay a basis for the location control on a standing-up robot and the mechanical research on the sit-to-stand process of the patient.
