    摘要： The present invention relates to active robotic gait training system and method which enables more active gait training based on remaining gait ability of patients with gait disorders by estimating the gait cycle through measurement of slope of the lower leg, operating the hip joint and the knee joint by an actuator depending on the gait cycle and operating the ankle joint by functional electric stimulation (FES).The robotic gait training system contains the femoral support unit, the hip joint support unit and the lower leg support unit. Also, The robotic gait training system has further comprising: a support fixing toe tip, located on the lower part of the lower leg support unit and fixed the strap connecting to the toe tip pad wrapping the toe tip (forefoot); a tilt sensor, installed on the lower part of lower leg support unit or on one side of the toe tip pad; the control unit generated FES control signal, hip joint angle control signal and knee joint angle control signal by using slope signal received from the tilt sensor; a first linear actuator operation unit, received the hip joint angle control signal from the control unit and operates the first linear actuator to rotate the femoral support unit based on the hip joint angle control signal in the hip joint unit that is the coupling unit between the femoral support unit and the hip joint support unit; a second linear actuator operation unit, received the knee joint angle control signal from the control unit and operates the second linear actuator to rotate the lower leg support unit based on the knee joint angle control signal in the knee joint unit that is the coupling unit between the lower leg support unit and the femoral support unit.
