What is the weight? Is it available on the site yet?
Very neat. Looks very well machined.

I was wondering who would be the first to release a complete swerve solution. This looks very good, but I have a few questions:
How much would one cost?
Where would an encoder be mounted?
How much would one weigh?
What's the final gear reduction?

Re: pic: Revolution Pro, mount with 2X CIM and Versa
 

No price as of yet...this was a custom build. The propulsion only unit sells for $550 complete.

Weight as shown is 11.2lbs

Ratio shown is 7.46:1

The propulsion shaft is from a Cimplebox...so the propulsion encoder goes underneath. The main mount plate has the features for mounting a US Digital encoder.

The steering has some features for mounting a sensor, but the Versa shaft needs to be modified to use them. The unit shown has no mods for a steering sensor. The customer will supply their own.

I gotta ask. What exactly is that $550 including? Is the turning gearbox included in this price as it isn't for propulsion. How about turning and driving motors?

Re: pic: Revolution Pro, mount with 2X CIM and Versa
 

Even if the $550 included one entire module, motors and everything ready to go, $2200 for 4 swerve modules would be tough to justify spending more than half you budget on for a lot of teams (if the budget is (~$4,000 still). Even a discount for buy a whole set would still take a huge chunk of change.

Very cool build. Like the simple mounting mechanism/pattern.

Re: pic: Revolution Pro, mount with 2X CIM and Versa
 

The $550 price quoted was in reference to the propulsion only unit.

The full combo unit with steering sells for closer to $700.

These assembled units aren't necessarily targeted to FRC. Revolution modules are popular for FRC, but these complete units are generally sold in the off-season or in other hobby markets.

We just like to share. CAD pictures are cool, but hardware in hand is cooler. :)

Wow, that's a lot of cash.
You could make it work with a 3-wheel swerve I think. But that's still $2100 without encoders.

Re: pic: Revolution Pro, mount with 2X CIM and Versa
 

I love swerve but they are resource hogs.

I think that this is great for off-season and practice robots. When it comes to the competition robot, teams may have to make a lot of the components themselves in order to meet the $4K limit.
