End effector

Definition

An end effector is the device at the end of a robotic arm or manipulator that interacts with the environment to perform tasks such as gripping, welding, or cutting. It serves as the interface between the robot and the objects it manipulates, making it a crucial component for functionality in various mechanical systems and robotics applications.
