END- EFFECTOR -
The end-effector is the "hand" connected to the robot's arm. It is often different from a human hand - it could be a tool such as a gripper, a vacuum pump, tweezers, scalpel, blowtorch - just about anything that helps it do its job. Some robots can change end-effectors, and be reprogrammed for a different set of tasks.
If the robot has more than one arm, there can be more than one end-effector on the same robot, each suited for a specific task.
