WitrynaDue to the complexity of manipulator robots, the trajectory tracking task is very challenging. Most of the current algorithms depend on the robot structure or its number of degrees of freedom (DOF). Furthermore, the most popular methods use a Jacobian matrix that suffers from singularities. In this work, the authors propose a general … Witryna2 gru 2024 · Resolved-rate motion control allows for direct control of the robot’s end-effector velocity, without expensive path planning. In surgical robots, it is often necessary for the robot arm to move in a straight line at a constant velocity as it lacerates tissue. This controller would be well-suited to the task.
