Art... I must say you amaze me. I have been seeing your creations lately on chiefdelphi. This is the most effective vex robot I have seen for Triple Play. Very well designed and very creative.

How long will it be before I break the six-foot height for Vex?

I would guess in the next 2 weeks. Can't wait to see what's coming next.

Sweet!

I wonder if the server rails we used in our tower/shuttle were the inspiration for these additions to the VEX line up? Or maybe it has something to do with Rack Solutions ties to VEX Labs. I'm sure john could clear this up for us.

The server rails we used on 229 last year are from the Accuride 2907 series. These are low-friction slides using ball-bearings. (I used these rails last summer, during my RackSolutions internship. When we were designing our 2005 robot, I remembered them and integrated them into our elevator.)

The VexLABS-Slide Rails are patterned after a different (simpler), friction based design. (No bearings). That RackSolutions came up with for some of our medium duty applications. This design was easily adapated to Vex.

The basic design is that there are 2 "C" sections, which sit inside each other. They slide back and forth on their "corners" and not on their edges, which provides a happily low-friction motion, while maintaining good linear allignment. (See attachment.)

I'm very proud of this rail design, and can't wait to see it released as a product. Art certainly proved to us that it will be well utilized. We at VexLABS continue to be impressed by the high quality of his robot designs, and of his dedication to the Vex program.

Thanks Again Art!
