We split the fall training season into 2 parts:
First we spend September and half of October doing training each sub-team (Mechanical, Software, Electrical, Systems, and Business), meeting for 2 hours 1 once a week.
Then we run a miniature build season for 6 weeks in October / November (meeting 3 hours 2x per week most weeks, plus two 7-hour Saturdays). Our Systems team designed the game over the summer. It's simpler than the real games typically are, but is intended to get new students accustomed to deadlines and working in groups. It also offers the chance to design and integrate a complete robot, which we think is valuable.
We don't do much during December - partly because people are busy with holidays and travel, and partly to give them time to rest before the gauntlet that is build season.
