Things that caught my eye:
- Has a lightweight look. Nice.
- The encoder disc is redundant. You could use the wheel spokes with no weight penalty.
- The rear of the hood may give better results if it is continuous. Check out the Killer Bee's hood on frc-designs for an elegant way to do this.
- Using two separate gearboxes to drive your wheel is weight inefficient. Use something like a CIMulator to mount both motors together. Less mounting bracketry, and only a single gearbox housing. Also frees up one end of your wheel shaft for a shaft encoder, if you don't use the wheel spokes.
- If you haven't prototyped it, consider two wheels with a space between. This may effect your accuracy. Let your test results guide you.
