A new kind of double foot bionic electric mobile platform based on MATLAB is proposed. Virtual reality toolbox, video acquisition Toolbox, GUI and Simulink are used to complete the whole simulation, in which a 3D lower limb model is built and drived. In GUI, the movement of lower limbs is got by a camera, then the changed angle data of hip joints, knee joints and ankle joints in movement are extracted, and the data of the lower limbsmorement are stored.
