What does the term "end effector" refer to in robotics?

The term "end effector" refers specifically to the device or tool that is attached to the end of a robot arm. This component is critical for executing tasks because it interacts directly with the environment or the objects that the robot is designed to manipulate. End effectors can take various forms depending on the application, such as grippers, welders, scissors, or suction cups, and they are designed to perform specific functions such as picking, placing, cutting, or assembling. Understanding this terminology is fundamental in robotics, as it helps in designing and programming robots for tasks in various industries, from manufacturing to healthcare.
