That's of course assuming your pilot is the one in the airship. With just two people up there, you can't always guarantee that. But especially in Michigan where there are so many talented teams that's probably less of an issue.

The low angle of the human load collecting mechanism also makes the loading faster and more reliable than other mechanisms.
Hmm that may be true, but I can't really see how this design allows for the robot to deposit the gear on the spring and drive away without the pilot fishing it out...am I missing something?

Yes, you're correct. The pilot has to lift the gear out of the robot before the robot can drive away. We're confident that whatever time you could save by dropping it off without the pilot isn't worth the additional complexity.

Ok our team designed a passive gear deliverer system too, we are testing in a few days at a practice field...hopefully you are right about the less hassle! Do you think having a drivetrain that allows linear strafing would also save time when depositing?

Depends. Have you done linear strafing in the past? Are your drivers familiar with it? It isn't going to help much if your drivers aren't used to it, especially considering that opposing robots can push you sideways much more easily.

Edit: Also, your drivetrain should probably have been decided upon and built by this point. If it has not, take your kitbot and build a tank drive. Week 4 is not the time to make these sorts of decisions. Source: my team did mecanum last year, and had no idea what we were doing. If you do decide to go this path, send me a PM, because there's a few things you'll need to know.

I suppose it could. We've had good results with our tank drive by turning right before getting to the airship and approaching the peg head on. As far as drivetrain decision making, the cycles to and from the peg are probably more important than placing - you need to be very fast maneuverable, and ready to deal with pushing.
