Re: pic: Team 449 Hex Drive

We considered integrating the angle supports into the base frame, but we didn't like how much real estate the supports we considered would take on the 2x1.

Although having a raised secondary frame is heavier, we like the fact that it gives us more vertical space to place pneumatics and electronics. (Our robot for last season was a bit of a mess in terms of packing and that experience heavily influenced this drive's design process).

Additionally, we're at least trying to mitigate the weight gain from the hex superstructure by fabricating the base and inner rails on the superstructure with 2"x1"x1/16" and 1"x1"x1/16" (we normally use 1/8").

Also we're using versawheels mostly to experiment with how well they perform compared to colsons. It's an experimental offseason project, and we figured we may as well try out as many new features as possible.
