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 robot-ic 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 paint-ing 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)
