What function does the FANUC robot's "teach mode" provide?

The "teach mode" of a FANUC robot is specifically designed to allow operators to manually record positions and movements, which can then be used for programming the robot’s paths and tasks. In this mode, an operator can physically manipulate the robot to reach desired points in space, and the robot will memorize these positions. This is essential for creating a precise program that can be executed repeatedly, as it enables customization for specific applications and ensures accuracy in the robot's operations.

Teach mode is particularly useful for tasks that require fine-tuning and adjustments because it allows for direct interaction with the robot's movements in real-time. This capability is vital in environments where the robot needs to adjust to various workpieces, tooling, or operational changes.

The other options relate to functions that are not primarily what 'teach mode' is intended for. Automating the programming process is typically a feature achieved through other programming methods rather than manual teaching. Testing safety features is generally conducted outside of regular programming and involves protocols that ensure the robot operates within safe parameters. Connecting to external sensors involves interfacing and programming specifics that go beyond the scope of what is immediately done in teach mode.
