| Abstract: | Accurate and real-time gait phase detection is basis of control of intelligent prosthesis and other rehabilitation robot,a real-time phase detection system is proposed. Four foot force sensors and two attitude sensors are used in the system,which can detect phases of heel strike,foot flat,heel off,toe off,swing flexion and swing extend during walking on level ground. The experimental results show that the system can adapt to different walking velocities,different stride length of different subjects,and the experiment of prosthesis control is performed to prove the gait phase detection system can be used to real control of prosthesis. |
