This disclosure provides a robot control method, apparatus, device, and computer-readable storage medium. The method estimates the Jacobian matrix of robot motion based on real-time acquired robot motion data and establishes an optimization problem for a specific task based on physical constraints on the joint angular velocities and accelerations of each joint of the robot. This determines the control information for the robot's joint angular velocities, thereby achieving precise control of the robot's motion. This method enables fast and accurate robot motion control based on data-driven approaches even when the robot model structure is unknown or inaccurate, reducing computational costs and control errors caused by inaccurate structural information, and effectively reducing joint angular deviations during task execution. Furthermore, by limiting the robot's joint angular acceleration, it solves the problem of discontinuous speed or even motor damage caused by excessively large joint angular acceleration.
