Hybrid position/force control

Definition

Hybrid position/force control is a robotic control strategy that simultaneously manages both the position and force exerted by a robotic system, allowing for more adaptable and dexterous interactions with objects. This approach is essential in manipulating environments where precise positioning and controlled forces are necessary, enabling robots to perform complex tasks that require flexibility, such as grasping and manipulating delicate or variable objects.
