What Are The Different Parts Of A Robotic Arm

If you’ve ever seen a robot arm in action, they are pretty amazing pieces of machinery.

Do you know what all the different parts of a robotic arm are? If not, don’t worry. You’re about to find out! There are quite a few different parts, each with a specific purpose.

Let’s take a closer look at the five core parts.

Joints And Actuators

Joints are essentially where each of the other parts meet and move together. They can be positioned differently to give the robotic arm flexibility and motion.

End Effector

The part that makes contact with whatever it’s trying to pick up or grab objects with is called the robot end effector. The three main types of end effectors are grippers, vacuum cups, and suction cups, and all of these have different purposes depending on what the robotic arm is being used for.


Linkages are the next part of a robotic arm and are responsible for attaching the end effector to the joints. They help distribute movement throughout all parts of the robot, ensuring that each moves in sync with the other.

Internal Sensors

The final part of a robotic arm is the controller and software. This controls the different parts, telling them when and how to move. Additionally, internal sensors provide feedback on how each part moves and may be used to adjust the movement accordingly. Overall, these five core parts work together to give robotic arms their incredible functionality and flexibility. Whether they are used in manufacturing, research, or other applications, they play an important role in modern society.

Power Source

Another vital part of a robotic arm is the power source. This typically comes in the form of an electric motor, providing the necessary energy to move all the different parts. Depending on the specific use of the robot, there may also be additional power sources such as batteries or hydraulic systems. Regardless of how it’s powered, however, a reliable source is essential for the effective operation of a robotic arm.

Overall, many different parts work together to make a robotic arm function. Whether used in manufacturing or research, these intricate machines enable us to do things we otherwise couldn’t. From gripping objects to distributing movement throughout the entire arm, each piece plays a vital role in making these robots a reality. So if you ever get the chance to see a robotic arm in action, be sure to take a closer look at all the different components that make it work!

Some Other Parts To Note

Depending on the specific application of the robot, there may also be additional accessories or attachments, such as a camera or different end effectors for grasping and manipulating objects.

Wrist and elbow

Another key part of a robotic arm is the wrist and elbow, which allow for more precise, flexible movement of the end effector. This can be particularly useful in tasks like delicate assembly or precise manipulation that would be difficult with a traditional fixed-joint robot arm. Overall, these different components work together to give robots their incredible dexterity and functionality. Whether used in manufacturing, research, or other applications, robotic arms play an important role in modern society.

Drive train

The system is responsible for translating power from the power source to the various joints and other robotic arm components. This may consist of gears, pulleys, belts, and more.


Typically a computer or microcontroller controls all aspects of robotic arm movement, such as which joints to move at which times and how much force to apply. This is often referred to as the robotic arm’s “brain.”

Communication system

Robotic arms may also have a communication system that allows them to communicate with other devices, such as computers or humans. This can be accomplished through wireless or wired connections and enables greater versatility in the types of tasks that robotic arms can perform.

Motors and gears

These help power the robotic arm by transmitting its movement from joint to joint. Motors are generally electric in nature, while gears are often used to change the speed or direction of movement. While these are not technically considered parts of the robotic arm, they play a crucial role in its functionality.

A robotic arm comprises many different components and systems that all work together to give it incredible versatility and functionality. Whether used for manufacturing, research, or other applications, these machines are indeed a fantastic feat of engineering!
