The present application belongs to the technical field of
lower limb training
robot, and specifically discloses a
robot lower limb training method, comprising the following steps: step 1, fitting a hip
joint rotation angle change curve, a center of gravity up and down position change curve and a center of gravity
forward speed change curve according to
gait information of a
human body; step 2, using a
gravity compensation PD
control algorithm to control rotation of an
exoskeleton motor according to the hip
joint rotation angle change curve; using a PD
control algorithm with weight reduction bias to control rotation of a lifting motor according to the center of gravity up and down position change curve; and using a PI
control algorithm to control rotation of a bottom wheel according to the center of gravity
forward speed change curve; the present application provides a
robot and a
lower limb training method capable of improving human-computer interaction compliance.
