for y'all who suck at killing robots, their weak spot is their chest, unlike organics like mutants and humans, where their weak spot is the head.
assaultrons are easy peasy if you shoot the chest. same for protectortrons. sentry bots just aren't weak until they overheat. when they overheat, shoot their fusion cores in the back.
also, wasn't there supposed to be robo-brains in the game?
