Embodiment 1
[0039] In an exemplary embodiment of the present invention, as Figure 1-Figure 4 As shown, a motion control method for quadruped robot based on reinforcement learning and position increment is presented.
[0040] like figure 1 As shown, different from the existing gait control methods of quadruped robots, this embodiment proposes a quadruped robot motion control method based on reinforcement learning and position increment, which allows the quadruped robot to learn the sole of each time step. The amount of change in position, avoiding abrupt changes in control commands, enables the quadruped robot to learn smooth and coordinated movements within the RL framework and reduces the difficulty of hyperparameter tuning during the training phase. Reinforcement learning needs to interact with the environment to learn, and the trial-and-error and randomness of the strategy in the early stage of training is likely to cause irreversible damage and damage to the robot, making it impossi...
Embodiment 2
[0088] In another exemplary embodiment of the present invention, as Figure 1-Figure 4 As shown, a motion control system for quadruped robot based on reinforcement learning and position increment is presented.
[0089] include:
[0090] an information acquisition module, configured to: acquire motion environment information, quadruped robot posture information and sole position information;
[0091] Incremental calculation module: configured to: based on the obtained information, generate the position of the sole of the foot in each preset time step when the quadruped robot moves, and calculate the variation of the position of the sole of the foot in each time step;
[0092] The trajectory planning module is configured to: take the maximum moving distance in a single time step as a constraint, and accumulate the time step to obtain the plantar position trajectory;
[0093] The action control module is configured to: control the quadruped robot to perform corresponding action...
