According to Mitchell B. Goldsteen the system targets equipment like haul trucks, loaders, and bulldozers at construction sites, quarries, and industrial plants. Workers often have to manually operate heavy machinery that is expensive to maintain and difficult to maneuver. For example, when a mechanical arm has to lift something over or around another object, it?s hard for the human operator to judge whether he?s lifting too high or too far back?and if he misjudges by just a few inches, he could easily cause thousands of dollars worth of damage to either the object he?s trying to lift or the object he?s trying to avoid.
