The robots are placed at the bottom of the cones and barrels and are small enough not to greatly change the appearance of the construction aides. It would look exactly the same, Farritor said. Normally theres a kind of rubbery, black base to them. We replace that with a robot.
Farritor has talked with officials from the Nebraska Department of Roads about how the robots would be most useful to what they might need.
The robots could come in handy following a slow-moving maintenance operation, like painting a stripe on a road or moving asphalt, where now the barrels have to be picked up and moved as the operation proceeds. That way you dont have to block off a 10-mile strip for the operation , Farritor said.
While prototypes have been made, they are not in use anywhere. Farritor said he has applied for a patent and is considering what to do next. He is thinking about starting a small business. He is also thinking about marketing the robots to roads departments and others across the country who may benefit from them.
