Good stuff:
The overall design is nice. Coaxial, that's a plus. Shifting is great. I really like what you're doign for turning the module, as it saves a ton of space. Efficiency with worm gears and mounting could be problematic, but that's just to me. The overall space usage of thise drive looks really good, as most of it hangs over the 2x1 or other elements of the chassis.

First off:
What size wheels are those? 6"? Anything more than 3" is overkill IMO unless the game demands it. Smaller wheels means smaller axles, lower gear ratios, and overall much less weight. If you flip your CIMs upside down, it will be much more workable with those size wheels.

What are you trying to solve with the shifting mechanism? The massive amounts of weight that cylinder and its mounting will add to your drivetrain is not worth the change from ball or dog shifting.

What is the total weight? #2 problem with swerves (behind complexity) IMO is weight and space, especially because you are only running 4 cims. Space looks good, but what is the overall weight of the drivetrain? Optimizing this would be great.

Also, plan for failure (in a manner of speaking). Will it be easy to swap out modules between matches? Especially with that shifter.

the mounting for the steering isn't really a problem any which way just needs to be worked out. The worm is just one idea and a place holder, there are several options we can do for steering.

yes those are 6" wheels. the point was to start large and we can design down if need be but from previous years there may be a need for large wheels so good to have the option.

the goal of that shifter is just having a shifter at all. we can certainly use other systems but that's what just initially came to mind in regards to weighing a minimal amount and ease of construction.

the weight is unknown. our goal is to start off with the lightest materials available then upgrade parts as they fail. because yes weight always comes up as an issue.

aha oh yes failure... no matter how hard you try it's always just around the corner =p At least from this design everything is easily accessible and swappable. a screw or two(and maybe a retention clip) and absolutely any part on this should be able to be easily replaced.
