Re: pic: Quick-Change Chassis 2
I don't think that's accurate. I'd say if we actually hooked up everyone's robots to a dyno and tested their actual drivetrain efficiency, there would not be many with greater than 90% efficiency....

Re: Variable Speed Gearboxes?
On that note, CVTech is another company that makes belt CVTs that are popular with Baja SAE. But CVTech's are even bulkier than Gage's, and I think the design on Gage's would be better suited for...

Re: Variable Speed Gearboxes?
I actually spent about a month of my life obsessing over this exact idea. And aside from the CAD practice I got from it, it was mostly a waste of time. You run into a whole host of issues as your...

Re: Robot in 3 Days 2017
As I reread my own post, I realize the "too proud" bit came off a little harsh. The reason I worded it as such and agree with that sentiment is because I have fallen victim to that mistake. You...

Re: Robot in 3 Days 2017
I'd love to see this just because I think it'd be a lot of fun as well. Also, the logistics would be difficult, but it'd be awesome to get 6 Ri3D bots at one event and let them duke it out.

Re: Robot in 3 Days 2017

Re: CIM Like motors for non-FRC use
It honestly sounds like the CIM is what you're looking for. The issue you'll run into is that what makes the CIM so robust and so dependable is, in part, its weight. [WARNING: Over simplified...

Re: New AndyMark Product Game Hint???
Are you referring to this wheel in the AndyMark teaser? That hex bore looks pretty small. Is that a wheel AndyMark just had laying around, or do you think that's an upcoming product?
