What Is EOAT? An Essential Part Of Robotic Processes

Robots are only as important as their parts’ purpose are. Well, robot arms are a crucial aspect of robotic technology. So, what is EOAT?

Surface Definition

EOAT stands for End Of Arm Tooling. It refers to the equipment that interacts with parts and components. Typically, at the end of a robotic arm. For example, the welding torch on a robotic welding system.

Moreover, the EOAT gives a robot a specific purpose and functionality. On the other hand, the EOAT changes its form to fit different applications. Also, you can decide to build it to accommodate several processes at once.

Either way, robotic capabilities mostly depend on EOAT advancement capabilities.

Types Of EOAT For Robots

This is the list of the most common types of EOAT in the market. Specifically, for collaborative robots.


They are used for grabbing objects. Especially, grippers are suitable for assembling. Aside from that, it also fits with pick and place applications.

Mechanical grippers

Uses mechanical fingers to manipulate objects. Also, it has a design similar to a crab’s pincers. These type of grippers comes with adjustable force and strokes. The good part is that the fingers are replaceable. Thus, it allows you to make the most of your investment.

Vacuum grippers

This type of grippers uses suction cups. Mostly, it is used for handling workpieces with uneven surfaces or irregular shapes. Unlike traditional vacuum grippers, new models run on electricity. As a result, it has a low maintenance cost. In addition to that, it improves the work environment by producing less noise and dust.

Adhesive grippers

As the name suggests, it grasps objects by sticking instead of holding. Because of this, adhesive grippers usually pick up light-weight objects. Unfortunately, the effect on the grip will be lessening in each successful operation. That is because the adhesive quality is fading.


Attaching sensors to the robot extends your automation possibilities. Robots will now have the ability to perform operations that needs delicate handling. That diminishes the need for a finesse human hand. 

Collision sensors

The most important part about these sensors is that it prevents robots from hitting obstructions during its operations. Thus, avoiding damages. It either shuts down the robot arm or resets it to its original position.

Force/torque sensors

These sensors are essential for precision processes. Even in complex situations, it helps you to accurately pinpoint your command. Thus, giving you full control of your robot’s movement. It gives you precise force and torque measurements.


There are a lot of tools to use as an end-effector. However, in manufacturing companies, certain tools are more prevalent than others. Some companies choose to combine their tool with a sensor. As a result, they can gain optimal control of the production process.

Tool changers

Robotic tool changers facilitate an easy and quick change of tools. It can be done with just a few clicks. For example, when switching your welding gun out with a spray gun. Newer tool changers are designed to be lightweight as to not unnecessarily impact the payload of the robot arm.
