operational (task) space control
A more intuitive control method that treats the end-effector as being attracted to a goal position by a virtual force (like magnetic attraction). The robot naturally finds its own path to the target without explicitly calculating joint angles.
Operational space (task-space) control is an advanced control method that commands the robot at the end-effector level rather than individual joints. Instead of specifying joint angles, the operator specifies desired end-effector position and orientation. The controller uses a virtual force/impedance model—imagining the end-effector as being pulled toward the goal by a virtual spring or magnet—allowing the robot to naturally find its own optimal path without explicit inverse kinematics calculations.
Simple idea: Tell the robot "move the gripper here," and let it autonomously figure out how to bend its joints to achieve that task, adapting naturally to obstacles and forces.
