Resumen
In order to promote the development of sports training robots and improve the training of lower limbs in Sanda, a newmechanical structure of Sanda training robots is designed. The thesis combines the mathematical method of fractionaldifferential equations to design a new type of omnidirectional moving platform mechanism, which realises the movementin any direction in the plane and can turn at any radius during the movement. From the perspective of kinematics, themathematical relationship between wheel speed and robot trajectory is analysed, and a virtual prototype technology com-bined with Pro/E and Adams joint modelling and simulation method is used to establish an accurate and reliable virtualprototype model. The experimental simulation results show that the designed virtual prototype model is consistent with themathematical model, which verifies the practical feasibility of the mechanical structure of the lower limb power generationrobot for Sanda movement, and provides a reliable basis for the establishment of the physical prototype
