This is a very interesting problem.
Q440 reversed some long standing precedents about what it meant to be a robot, and now this Q&A reverses precedents about how we can help other teams.
Currently I believe teams can build two robots and inspect which ever one they want prior to a match, but they can't loan an assembled gearbox to another team. This isn't the FRC I know and I don't like the changes. Maybe all of this is part of this crazy year they are putting us through, but I sure hope it all goes back to normal next year.
I can only assume the answer Q461 is to prevent teams from installing super fast can burgler mechanisms on their 3rd/4th picks at champs. If it is to prevent ramps, it's clearly an over correction.
Even for the can burgler mechanisms it doesn't help that much. Champs elimination alliances have from 8:30am to 2:30pm to build a world class can burgler on their 3rd or 4th pick before they play on Einstein, that seems doable.
