"We had the circuit breaker, which had an issue with the electrical protection. In order to remove that breaker, it would be too hazardous for a human to go in there, so we’d have to make a larger outage to a bigger system. It probably would have taken several months to get to that point where we could do that work. And they asked if there’s a way to do it safely by using a robot to eliminate that hazard from the humans."
