What are end effectors typically used for?

End effectors are critical components of robotic systems as they provide the means through which robots interact with their environment and perform specific tasks. They are designed to execute a wide variety of functions depending on the application's requirements. For instance, they can be equipped with tools that enable actions such as drilling, welding, or cutting, making them versatile in industrial settings.

The versatility of end effectors allows them to adapt to different tasks, which is essential in manufacturing and assembly processes. Therefore, option B accurately reflects the primary purpose of end effectors and highlights their role in executing specific tasks within a robotic system. This is why they are an integral part of a robotic arm or manipulator, allowing it to perform complex operations that might be too detailed or dangerous for humans.

In contrast, the other options focus on roles that do not represent the core functionality of end effectors. For example, while general robot maintenance, programming, and design are essential aspects of robotic systems, they do not pertain directly to the functions performed by end effectors.
