Hybrid position/force control

Definition

Hybrid position/force control is a control strategy that enables robots to simultaneously manage both the position of an end-effector and the force exerted by it on an object. This approach is particularly beneficial in tasks requiring precision and compliance, allowing for better interaction with varying environments or delicate objects. By combining these control methods, robots can adapt their behavior based on external forces, making them more versatile in applications like assembly or manipulation.
