Hackers Take Note:

A University of Nebraska professor has developed robotic cones and barrels that 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 a.m., the cones could move from the shoulder to block off the lane at that time, then return to the side of the highway at the end of the day.
