Are you guys talking about total automated robots? Or remotely controlled robot drones?
If it is the latter, they will be easier to control as every move of theirs are basically a direct result of the human operator controlling them. However, it is not without weakness. As the link between the operator and the robots can be jammed or even hacked to take over the robots.
If it is the former, then it could mean trouble on many levels.
First, if they can be perfect and totally replace the human soldiers, then are we looking at the Judgement Day, Skynet... anyone? lol
If they are very primitive and flawed, then they certainly can be shooting at everyone they see and even malfunction to the point that they will target their own forces. Sure there can be some kind of fail safe remote control to have malfunctioned robots to be turned off or even self-destruct, but what if these fail safe systems are hit and damaged first?
Either way, I think remotely controlled robots is the lesser of two evils. Just my opinion.
