These robotic cones and barrels can move out of the way, or into place, 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 block off the lane at that time. And they can return to the original 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 remove 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 fund allowed Farritor to work on the project with graduate students at Nebraska and his assistant Steve Goddard. |
