Robotic Highway Cones
A University of Nebraska professor has developed robotic cones and barrels. These robotic cones and barrels can move out of the way, or into ___51___ , from computer commands made miles away. They can even be programmed to move on their own at any particular part of the day, said Shane Farritor, an assistant professor of mechanical engineering at Nebraska.For example, if workers arrived at 6 am, the cones could move from the side of the highway to ___52___ off the lane at that time. And they can return to the ___53___ place at the end of the day. “It just seems like a very good application for robots.” Farritor said. “The robotic cones would also help ___54___ people from hazardous jobs on the highway putting barrels and cones into place,” Farritor said in a report on his creation.
Work on the idea began in 2002 using a National Academy of Sciences grant. The ___55___ allowed Farritor to work on the project with graduate students at Nebraska and his assistant Steve Goddard.
The robots are placed at the bottom of the cones and barrels and are ___56___ enough not to greatly change the appearance of the construction aides. “It would look exactly the same,” Farritor said. “___57___ there’s a kind of rubbery, black base to them. We replace that ___58___ a robot.”
Farritor has talked with officials from the Nebraska Department of Roads about how the robots would be most ___59___ 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, ___60___ now the barrels have to be picked up and moved as the operation ___61___. “That way you don’t have to block off a 10-mile strip for the operation ,” Farritor said.
62___ prototypes have been made, they are not in use anywhere. Farritor said he has ___63___ for a patent and is considering what to do next. He is thinking about starting a small business. He is also thinking about ___64___ the robots to roads departments and others across the country who may ___65___ from them.
