You know those bright orange and white “bollards” placed on roads to direct traffic at construction sites? They are placed by construction workers, a task long considered to be quite dangerous. New robotic bollards have been developed that deploy themselves with the assistance of a human operator kept safely out of harm’s way. According to the developers, the two primary obstacles to acceptance are price (expected to fall rapidly) and the availability of user-friendly software interfaces (currently being created). I think I might actually have beaten Marshall Brain to the punch this time!
