I know it's difficult to do, but sometimes you just gotta be the bad guy. Don't allow PSPs or other games there - or set aside a time when they can do that stuff. Let them know that when they're in the robotics room, they're doing robotics stuff. Lay down the law early and hard, they'll get the point. The ones that are there for the right reasons will be relieved to be rid of the distractions; the ones that are there for the wrong reasons and probably would have been a negative aspect to your team will take care of themselves.
I'm not saying make it a sweatshop; during the build season we take about 45 minutes to play football, take our minds off things for a while, not completely burn out. But before we do so, we set goals - when the goals are achieved, the team earns the privilege to goof off. Then we get back to work reenergized and refocused.
