On Monday, the robot went into the sewer system at Santa Clara and G streets in Downtown Fresno.
The robot is designed with a few bright lights on the front, with a camera to record everything it sees. The camera can also snap pictures. This is so crews can map every sewer connection in the design of the High-Speed Rail.
Crews will need to move some utility lines around and they need to know exactly where they are since blueprints of the system are not always accurate.
"It's one more step toward the final design of this project, knowing where the utilities are and the condition of it, is a very important part of the process," said High-Speed Rail spokesperson Elizabeth Jonasson.
Crews are doing this work overnight because it's the lowest "flow" cycle for the sewer system. The contracting crews will be out every night this week to finish mapping out the rest of the route through Downtown Fresno.
