Last I checked even military enlisted robots are not allowed to make firing decisions on their own.
"I had the opportunity to observe some of the DARPA challenge a few years ago, it was all tracked and wheeled vehicles."
A walking 6,4, or 2 had no chance in this competition.
However if this was held in the raw wooded area of Northern Michigan all these tracked and wheeled vehicles would not have made 50 feet from home. (unless one was a bulldozer)
Desert or city streets and woods or jungle very different. Here is the love for walkers even if they do not shoot.
I wonder how much money was spent on that video above but it shows how far we have come in the last 2-4 decades.
What do the the next 40 years have to show off or is there a peak and not much new?
