The Core Components of a Robot Manipulator

A robot manipulator typically consists of several key components that work together to provide the desired functionality. Here are the main parts:

1. Joints

Joints are pivotal in a manipulator as they provide the degrees of freedom necessary for movement. The more joints a robot possesses, the more dexterous it is. For example, an industrial robotic arm often has 6 joints, allowing it to replicate a human arm's flexibility.

2. Links

Links are the segments of the manipulator that connect the joints. They can vary in length and material, depending on the tasks the robot needs to perform. For instance, a lightweight aluminum link might be used for quick movements, while sturdier steel links could be employed for heavy-duty applications.

3. End-Effector

The end-effector is the part of the manipulator that interacts with the environment. It could be a gripper, welding tool, or even a camera, depending on the manipulator's intended purpose. When discussing what is a manipulator in robotics, it’s essential to highlight that end-effectors are crucial for task completion.

Types of Manipulators in Robotics

Manipulators come in various designs, each tailored to meet specific requirements. Here are a few common types:

1. Cartesian Manipulators

These robots move in straight lines along the X, Y, and Z axes. They are often used in tasks requiring precision, such as 3D printing or assembly applications.

2. Articulated Manipulators

Articulated manipulators feature rotary joints and are more versatile in their range of motion. Commonly found in manufacturing, they can perform tasks like welding or painting with ease.

3. SCARA Manipulators

Selective Compliance Articulated Robot Arms (SCARA) are designed for high-speed, precision-oriented tasks, making them popular in assembly lines.
