Re: choosing the right driver
The coach should be picking. They know what they want from a driver and who they can work with.
Thinks to look for when picking driver
1) Following the rules
2) Following the rules
3) Following the rules
5) How well he/she works with the co-pilot
6) Will listen to the coach
7) Comfort with being on the spot
Our drive coach holds a series of 3 tests. The tests contain things about the robot and game rules. Whoever passes is then up in the running for drive team. The ones who passed tell the coach their first choice of what role they want to fill (driver, co-pilot, or human player).
The ones who want to drive and the ones who want to co-pilot take short runs with eachother in a round robin fashion so everyone drives with everyone at least once.
Our coach pretty much picks the two who worked the best together.
If you don't have a practice robot or something, use a previous year's robot.
