We have a uPrint SE that we love to prototype parts with and we made some spacers that we used on our 2013 robot. Some of the things that we made were custom shaft attachments/couplings for the window motors.

This year we are working on our 6 wheel tank drive with 5mm HTD belts. We were looking at using the VEX Versa Hubs with the 42 tooth HTD pulley from Andy Mark. We decided to combine both parts and we now have an integrated pulley with hex drive that attaches to the VEX traction wheels. We are pretty excited about it but we will continue to test for strength.

We spent a lot of time researching how to create the actual 5mm HTD profile for the pulley and it took a few attempts to get it right but this 42 tooth profile is perfect now.


I see no reason why these will not be on our actual robot this upcoming season.
