What is manipulator in robotics？

In robotics, a manipulator is a mechanical arm or device designed to interact with objects in its environment—grasping, moving, assembling, or performing other precise tasks.Robotic manipulators are the backbone of modern automation, revolutionizing industries from manufacturing to healthcare. But what exactly are they, and how do they work?

1. What is a Robotic Manipulator?

A manipulator is a robotic arm that performs physical tasks by moving its joints and end-effector (such as a gripper or tool). Unlike mobile robots, manipulators are typically fixed in place but have high precision and repeatability.

2.How Does a Robotic Manipulator Work?

1. Programming – Engineers input commands (via teach pendants or code).
2. Motion Planning – The robot calculates trajectories.
3. Execution – Motors move joints to position the end-effector.
4. Feedback Loop – Sensors adjust for precision.
