Does your 4 wheel drivetrain work on carpet?

Looks awesome guys. It was a honor to sponsor and send you graphics, shirts and a bunch of other stuff. Thanks for the videos and all!

good job!! I've enjoyed watching you do this. I have a feeling that this could turn into an annual event... hmm?

It will work, but a 6 wheel with a drop center may work better, the channel has this feature built in to allow for that configuration. The idea was to swap to mechanums and show the difference in performance. Along the way we ran into a few problems.

First we did not have all the hubs we needed to mount the mechanums or it would have needed spacers to use to the FlexHub Flanges. Second, on test day we found out our game pad was busted and we had to drive the robot missing the second Y axis. This took some remapping of our brains to get it oriented, Mechanum would have been even more difficult.

Another option would be the kit chasis or the kitbot on steroids. Both great setups.

Our advice? Get a reliable drive completed and out of the way and then focus on your gameplay.

well as long as it has motors attached and wired (which it does) yes... the carpet used is very thin (think school/industrial carpet) and its only real purpose it do keep the robot from scratching the floor

By "work" I think he's referring more to the inability of a long wheelbase 4wd robot to turn on carpet. Any team that's ever had a 4wd robot drive great on their school's vinyl floors, only to get to competition and find that they can't turn well, if at all. A 6wd dropped center would fare much better, as Dan mentioned.

Quick question: Anyone know where to find the Modulox mounts for the Andymark PG71 motor? Or did you guys machine your own mount?

The FlexHub Flanges and #25 Chain Sprocket are available on AndyMark now. The Modulox PG gearbox mounts should be available soon, they have stock so check back frequently for the product page is available.

The Modulox PG Mount will mount the entire PG series such as the PG 27 used on the Indexer, and PG 188 used on the winch.
