IUPUI Ri3D Purdue School of Engineering

IUPUI is almost complete with our first ever Robot in Three days!
Updates are being posted as they happen onto our multiple pages.
We hope to be a resource to teams all around the country and in our area on how to easily build a competitive robot with easily accessible resources.

Thank you to all our sponsors who made this project possible
Andy Mark - donating money and supplies for our team

IUPUI University Student Council - for supporting our cause and financial support

Purdue Polytechnic High School Indianapolis - for also allowing us to use a school sanctioned space.

Thrifty Bot - for shaft collars, bearings, compliant wheels, brackets and many more!

Quick question about the intake. Is it in a fixed position during the match or do you plan on making it retractable? Thanks!

The intake will be retractable using pneumatics, in an update video tonight we will be going more in depth into the intake and such.


Few notes about all of the CAD:

  • Intake and Conveyor Compression should be increased from an inch to 1.5-2"
  • Piston Placement needs moved as the piston struggles to pull the intake up when full extended
    If you have any questions let me know!

Thank you to all of our sponsors, Andymark, Thrifty Bot, IUPUI, and Purdue PolyTechnic Highschool.

The code was made using the Command Based Structure.

Great work! I am wondering how you guys are staying there after climbing. I haven’t seen any brake mode on your code, maybe it’s switched on from the physical button. Also, haven’t extensively looked at the CAD yet. Is one Falcon geared 16:1 enough to hold it up? Or do you guys have anything else?

A very simple and cool robot! Do you have any uncut footage of the robot driving, intaking, and scoring? I’d like to see something like a 5-30 minute sample just to get an idea of what the intake should look like and how repeatable the scoring is. I loved the intake testing video but I want to see more about how it handles centering the ball, how quickly it grabs balls, etc.


We have a few clips of the robot driving and basically practicing, but unfortunately we used 3-d Printed pulleys due to our time constraint, and cause the intake to fail on our last night of testing, once we get new I’ll have a couple match long videos out.

We have nothing holding the robot up except for the Falcon in brake mode, and it holds almost perfectly. The robot falls VERY slowly once climbed however. Lastly the 16:1 is plenty.

  • Intake compression needs to be increased from 1in to either 1.5 or 2in
  • Bouncing balls are a problem, will be interesting how the game is played when <9 balls are laying around and multiple are bouncing
  • Add an intake protection bar. In the last 2 minutes of the day 2 practice, the robot takes an ugly hit straight to the intake, bending the shaft, and pneumatic piston connected to it.
  • Robots that shoot from the Fender will be VERY competitive

Hope you enjoyed the videos, if you have any questions feel free to ask!
