摘要： A walking robot and a control method thereof. The control method includes performing transition of a second leg to a toe-off state, when ground reaction force applied to a first leg exceeds a first set value under the condition that the first leg is in a swing state and the second leg is in a support state, performing transition of the second leg to the swing state and transition of the first leg to the support state, when ground reaction force applied to the second leg is below a second set value under the condition that the second leg is in the toe-off state, and achieving walking of the walking robot by repeating the transitions among the swing state, the support state and the toe-off state. Thereby, the control method allows the robot to more stably and naturally walk.

摘要： A walking control apparatus and method of a robot. The walking control method include confirming a swing leg and a support leg by judging a walking state of the robot when a walking velocity of the robot and a walking command are received by the robot, generating reference pitch knot points of a hip joint unit of the swing leg based on the walking state and the walking velocity of the robot, generating a target pitch angle trajectory of the hip joint unit of the swing leg using the reference pitch knot points, calculating torques tracking the target pitch angle trajectory, and outputting the torques to the hip joint unit of the swing leg to control the walking velocity of the robot. The walking velocity of the robot is rapidly and easily changed by adjusting at least one of a step length and a step time.

The knot point which is the angle command of the joint portion of each of the legs to perform the next step is compensated for based on the COM, and the compensated desired knot point is smoothly connected using the spline curve such that the robot walks similar to a human. In addition, in order to maintain balance while walking, the angle of the joint portion of the intermediate point of the current step is fed back and the knot point of the next step is predicted and adjusted, such that the robot stably and smoothly walks.
