FRC228- GUS 15

Absolutely amazing. This is the kind of robot I look at before each season to get inspired by and to learn from.

very cool.

do you have any more shots of the interior and/or chassis? i'm very interested in your chassis design, chain tensioning etc.

Always been a fan of GUS robots. Love the wide intake too. Does it pick-up two at a time? Only say one at a time in the video clip on the blog.

Thanks for the kind words!

The chassis design is one we've used for years. It is .090 alum, CNC turret punched frame. Our gearboxes are two speed VEX Pro ball shifter with the optional third stage in place. The wheel configuration is the standard 6wd, 1/16th inch drop center, 6 inch colsons with treads cut into the competition wheels. It's bulletproof and incredibly smooth. In the pictures below you can see some more details. We haven't had to use chain tensioning because the chain lengths were calculated out in the CAD before anything is even made. Through out the season we may experience a little chain stretch, in that case we just add some floating idlers to counter the stretch.

Packaging was difficult for us this year, so keeping everything as neat as possible was a must. Let me know if you have any other questions!

Just curious, why the treads cut into the Colsons? Aren't they plenty grippy? Did you have trouble with the grip in testing?

By our testing cutting the treads in the colsons increased the coefficient of friction by up to 30%, this summer we will be working on documentation to prove this. There is a reasonable difference in the amount we can push with our competition robot that is fitted with the cut colsons to the practice robot, that has just the left alone colsons. This will be the forth year driving with these colsons and I can say we rarely even come across someone we can't push!

Nice work guys, I'll be sure to stop by and get a tour of the machine this weekend.

So purty!

It can pick up two at a time and index them into our hopper rather well! Maybe I'll try to get a video tonight of the practice robot if there's time!
