Actually, apparently it doesn't vary that much.
In the first week or two, my team meets 3 days during the week and pretty much all day Saturday.
After that time, which is where we discussed design and stuff, we split up into groups which will work on various aspects of the design. For instance, last year we have a goal grabber team, a hopper team, an arm team, a drive train team, and a controls team. Each of these groups was responsible for getting their work down and was allowed to come in when they felt in necessary. I showed up every day, because I'm a loser like that (
) and I had time, but some groups continued to meet just a few times each week, as they had relatively simple jobs.
And the simple jobs thing brings up a point. As a rookie team, or even as a more experienced team, simple is good. It takes less time, is less likely to fail, etc. But even simple still means you stay up till midnight the day before ship.
