    Why is motion planning harder for 7-DOF manipulators than 6-DOF?

    Asked on Sunday, Nov 16, 2025

    Motion planning for 7-DOF manipulators is inherently more complex than for 6-DOF due to the additional degree of freedom, which introduces redundancy. This redundancy allows for multiple possible conf…

    Why do robotic grippers need force feedback during manipulation?

    Asked on Thursday, Nov 13, 2025

    Force feedback is crucial for robotic grippers as it enables precise control over the interaction between the gripper and the objects it manipulates. This feedback allows the robot to adjust its grip …
