Situations like this should be approached from two directions simultaneously.

First, work within the team as a whole to create an accepting atmosphere and culture. This is really a long term action item that never goes away. Don't put "jerks" in leadership positions. Have your leaders make a show of being inclusive - it's with everything we have to do during a season, it's rather easy to grab someone new and say "your helping me with this today". Have the occasional discussion about teamwork and the importance of everyone working on the team. Have team building activities away from the shop. All of this can help you create the proper atmosphere.

Second, approach it directly with any offending parties. Have a mentor or Teacher talk to them, figure out what's going on, and make behavior expectations clear. From the outside, it looks like one guy is being a jerk towards another. But for all you know there may be a good reason behind his feelings. Maybe the second guy ran over his cat, or they used to be best friends and had a falling out over a girl... Who knows. It's not just about telling the first guy to knock it off... You need to take the time to understand the root of the issue and help both parties deal with it in a productive way.

Finally, I will just add... Don't force them together until you figure out what's really going on. It can lead to fireworks and more hurt feelings, and ultimately disrupt the team. Don't treat them any different than anyone else, but there's a lot to be done on a robot, and it's easy to have them working on different things.
