Which component is typically adjusted to fine-tune the accuracy of robotic movements?

The tool frame is crucial for achieving precision in robotic movements. It determines the position and orientation of the end effector relative to the robot's coordinate system. By adjusting the tool frame, operators can fine-tune how the end effector interacts with objects in its environment, ensuring that the movements align closely with the desired path or target positions. This adjustment is vital for applications requiring high accuracy, such as assembly, picking, or welding tasks.

In contrast, while the end effector plays a critical role in performing tasks, the frame adjustments pertain to the positional data it utilizes rather than the effector itself. The base frame is fixed and represents the overall robot's position, making it less relevant for fine-tuning motions. The coordinate system provides a reference but does not directly manage the manipulation or adjustment needed for precise movements. Thus, it's the tool frame adjustments that specifically enhance the accuracy of robotic operations.
