They have allowed teams to register to avoid the crush on Thurs. They have allowed you to bring in one or two? carts of your pit materials on Wed night in the past. It will probalby come out in the Detailed Agenda when they announce the Divisions at Championship. They want you to wear safety glasses and gloves, and not to set up your pit area. Only uncrate the robot. Implicit in that is that your pit materials will be stored there until the pits open on Thurs.

Hope this helps!
Yes, you can put your batteries on charge as well (Sect. 3.6.2.3). None of us know until Thurs morning what our practice times are. you can also register your team during that time to avoid the Thursday crush.
