Hybrid Position/Force Control

Definition

Hybrid position/force control is a control strategy that integrates both position control and force control to allow a robotic system to effectively interact with its environment. This approach enables the robot to maintain a desired position while simultaneously regulating the force exerted on or by the environment, making it particularly useful in tasks where both precision and compliance are critical. The combination of these two control modes helps improve performance in applications like surgery, where delicate maneuvers are necessary.
