Re: pic: 6WD Sheetmetal Chassis
A few questions:
-What size rivets are they, and at what spacing?
-Why the 0.090" 5052? We looked at 5052 this year, but decided to go with 0.063" 6061 (and later decided we should have gone with 0.050" 6061). A thinner material would be lighter, and 6061 0.063" is strong enough for a FIRST robot with bumpers.
-Any details on the shifter, specifically the ratio and shaft design?
And finally, any plan to remove the transmission in vehicle if you ever have to? It looks like it would be very, very difficult to work on anything inside the transmissions as it is now. Even though it would possibly weigh slightly more, you could pocket out the space of the transmission side plate that is integrated into the frame, and put another plate over it. The transmission would then be a single assembly bolted into a hole on the frame.

The true beauty is, no matter what the game (Yes, even 2001), we spend these 6 weeks going crazy with design strategy, and trying to figure out a way to work the plot twists that the GDC throws at us...and its a blast. - Andy Grady [more]
