What is a robot end effector?
An end effector is the tool at the tip of a robot arm — a gripper, welding torch, suction cup or dexterous hand — that actually touches the work.

Definition
An end effector (or end-of-arm tooling, EOAT) is whatever sits at the end of a robot arm and interacts with the world: parallel grippers, vacuum cups, dexterous hands, weld guns, or inspection sensors.
How it fits
The arm positions and orients the tool; the end effector does the grasp, weld or measure. Changing EOAT is how one arm serves many tasks on a line. On humanoid robots, the "hand" is the end effector.
Why it matters
Payload, reach and cycle time specs are meaningless without the right tip. New tactile hands and swappable sensors (see DH-Robotics and Sharpa) are pushing end effectors from fixed tools toward general-purpose manipulators.
Frequently asked questions
Is an end effector the same as a gripper?
A gripper is one kind of end effector. Welding torches, sanders, cameras and multi-finger hands are end effectors too.
What is an EOAT?
EOAT means end-of-arm tooling — another name for the same idea in industrial robotics.
Why do humanoids care?
Humanoids often use dexterous hands as end effectors so they can pick up tools designed for people.
