A cable pulling robot is a key component of an automated system. Here's a breakdown of how a typical system works:

1. Preparation: The robot is inserted into one end of a conduit. A powerful, external winch or pulling machine is set up at the other end of the conduit with a pulling line.

2. Navigation and Guiding: The robot moves through the conduit, often controlled by an operator via a tethered or wireless control system. It can be equipped with a camera to inspect the conduit for obstructions or damage.

3. Cable Pulling: Once the robot reaches the other end, it connects to the pulling line from the external winch. The robot's function is not to pull the full load itself, but to pull the initial line that is then used to pull the heavier, main cable.

4. Automated Control: Advanced systems use sensors to monitor tension and speed, allowing for precise control that prevents the cable from being over-stressed or damaged.
