being a "Robert" refers to someone who constantly uses the same moves in a video game and/or camps. More specifically in multiplayer games. This "Robert" will constantly button-mash the same button or camp in the same area and then refer to his/herself as a "good player". He/she will defend themselves swearing it isn't cheating and is very fair.
Dude,quit being a "Robert" and stop pressing the square button!
