Another amazing looking bot from you guys Adam! Can’t wait to see you guys compete at Durham and hopefully DCMP.
Can you talk a little bit about your rollers? Is the bottom tube (or both) carbon fiber? Where did you source it? What material is your top roller? Why did you build a center crest on the top roller? How did you build the center crest?
Both rollers are carbon fiber. They are tubes with a 1.125"ID and a 1.25"OD we got them from one of our sponsors Apex Paddles they are used as paddle shaft for dragon boat paddles.
The top roller is tapered towards the center, this allows the ball to self center while rolling between the rollers. The tapered part is PVC 1.25"ID and 2"OD ordered from mcmaster (8749K44). it was turned on one of our lathes using a taper attachment to a 2 degree taper.
The rollers are driven by a 775pro, 10:1 reduction for the upper roller and 30:1 for the lower.
That looks very well engineered and very well executed.
Thanks! The students really knocked it out the park this year, with over 450 parts manufactured in house between the two robots. There where many days where all 12 manual machines and 5 CNC’s where going non stop from 8am to 9pm.

Looks amazing. Does it climb?
6 second level 3 HAB climb. Stay tuned for our video!

That’s the best and fastest implementation of that climbing strategy I have seen.

Very sweet climb. What reduction and, if present, locking mechanism does the wrist have in order to support the climb?
It’s a 775 pro at 560:1. There is no locking mechanism.

Here is a short video from some practice we where running on bag night. Bloopers, mistakes, un-refined coding and all included.

that’s a beautiful robot. hope to get the chance to see it in person!
are the bottom wheels on your climber mech powered? if not, how do you drive the robot onto the level 3 platform?

Loving the simplicity of this robot! Great job!
No they are not powered. We lift on the intake roller in the front. And use that to pull us forward.
What kind of gear reduction and how many motors do you have powering the roller? We’re looking at doing something similar but had issues with smoking motors. That may have been due to inconsistency in our testing.
Just 1 775pro at 30:1 the wheels on the rollers are 1-5/8
