A robot comprises a wheel-footed bimodal mechanical leg having a driving apparatus, a thigh unit, and a calf unit. A joint end of the thigh unit is hingedly connected to a joint end of the calf unit by a rotary shaft. The driving apparatus is connected to the rotary shaft by a transmission apparatus. The calf unit comprise a locking mechanism. The robot can operate in a footed mode and a wheeled mode. In the footed mode, the calf units and the rotary shafts in n mechanical legs are fixedly connected to each other, where n is an integer that is at least two. In the wheeled mode, the calf units and the rotary shafts in at least two wheel-footed bimodal mechanical legs are rotatably connected to each other.

This disclosure is related to a robot motion control method and apparatus. The method includes: obtaining a center-of-mass reference trajectory used for guiding the robot to execute a target motion; obtaining, based on optimization of an objective function, center-of-mass control information for controlling the robot to follow the center-of-mass reference trajectory to move; generating joint control information according to the center-of-mass control information and a structure matrix of the robot; and controlling the robot to execute the target motion based on the joint control information.

Robot motion control method and apparatus

A mechanical leg comprises a frame, a retractable member, a wheel, an extension and retraction driving member, a travel driving member, an auxiliary leg, and an auxiliary wheel. The extension and retraction driving member is located on a side of the frame. The retractable member is connected to the extension and retraction driving member. The wheel is connected to the retractable member. The wheel is further connected to the travel driving member. A first end of the auxiliary leg is connected to the auxiliary wheel, and a second end of the auxiliary leg is located on the frame. The retractable member extends under the driving of the extension and retraction driving member to drive the wheel to jump. The wheel is driven by the travel driving member to move. When the auxiliary wheel contacts the ground, the mechanical leg moves with the rolling of the wheel and the auxiliary wheel.
