In robotics, an end effector (or end-of-arm tooling) is the device at the end of a robotic arm, designed to interact with the environment. The exact nature of this device depends on the application of the robot. In the strict definition, which originates from serial robotic manipulators, the end effector means the last link (or end) of the robot. The most essential robot periferial is the end effector, or end-of-arm-tooling (EOT). There are very different application for EOT. EOT are frequently highly complex. They can carry out different activities at the same time and may utilize various sensors.
End effector types
-
- Mechanical gripper- two or more fingers that can be actuated by a robot controller to open and close on a workpiece
- Vacuum gripper- suction cups are used to hold flat objects
- Magnetised device- making use of the principles of magnetism
- Adhesive device- deploying adhesive substances these hold flexible materials, such as fabric
- Mechanical devices- simple devices, as hooks, scoops
The gripper of a bending robot is generally constructed by mounting multiple suckers on a metal frame.
Gripper system for robot bending
Depending the tasks in the robot-cell (workpieces nomenclature, weight of plates, measures of workpieces) the construction and functionality of end-effector is determined.
