1. Do most teams use version control, and what do they use?

My team (Team 53) uses git (via Github) to version our code. I've never tried other version control methods but I'm so happy using git that I don't see a need to experiment. In your post you mentioned that your goal was to get more people involved in the programming. Using a version control system didn't really help in that regard (at least for our team). If you look at our Github organization > 99% of the code we wrote was contributed by just two members.

2. Do teams use a build machine, or build server, and what?

We usually upload code directly from our personal laptops. Most of us have our own so it doesn't tend to be a problem.

3. Is there a solution to this problem of connecting to the internet and to the robot network at the same time?

You would have to hook up the router on the robot to the internet. This could be done with an adapter of some kind I suppose.

4. Is there a simulator that can help programmers?

Personally, I don't like to use robot simulators. They really aren't very good. I eliminate bugs by constantly rereading my code and fixing problems that I can detect before uploading.
