I was wondering what the typical weight and complexity of these systems was. This would be weight per module or, preferably, weight of bellypan + drive base + modules.
How long does this take to design? Does this need a particular special part or can it be fabricated with a waterjet/ sheet metal guy?
Any information on these drives would be useful, as I'm looking into different drives for a summer project.
Assigning names to a "design" is so limiting. That said a butterfly drive conventionally switches between 4 omni wheels and 4 traction wheels.

I would encourage you to sit down with your team and figure out a list of objectives you would like your summer project to fulfill. Once you've done this I would encourage you to use the chiefdelphi search function to read up on butterfly drives from older threads. Once you understand your design objectives, have an idea of where a butterfly type drive falls on that, and seen a number of designs other teams have already made you can properly assess if you should try to design and build one or if your time would be better spent working on something else. When done properly off season projects can be an extremely valuable resource both in terms of populating your team's design shelf and teaching students. The most important thing is to have a full understanding of why you are building what you are building and how you are trying to improve upon what you have done in the past, have seen others do in competition, or online.

Cheers, Bryan
