Our team started using AA batteries instead of the rechargeable battery pack.
But when they had to change the batteries, they had dismantle the robot to get
to the battery compartment. I am worried that the kids will not put back the
robot perfectly, if they have to do this just before the tournament to have
fresh batteries in. Is that how it is normally done?
thanks

Agreed - always use fresh AAs.
The recharchable batter has a goofy memory and the voltage drop will make
reproducibility for missions almost impossible.
