I just answered your question on chief Delphi, but for everyone else, here is a copy of my response: Because the cams that push on it have to straddle a bar, and it is easier to mount the cam mechanism in line with the chassis

@@aristeinfeld3687 Thank you!

@@LandonScharich Here is some additional explanation with pictures. www.chiefdelphi.com/t/ri3d-at-penn-state-2025-build-thread/477847/59?u=pennstateri3d

Driver is from THE swerve drive team, so he's pretty good at driving

The primary goal of these videos is education. FRC is a high school robotics competition, and the game just got announced. We build a robot in 3 days using the same parts they would use, showcasing our prototypes so the teams that don't know where to start can learn from us.

If you look at the shot at 0:22, you can see how the bot looks in starting position. The algae collector is folded in to fit inside the perimeter at the start of the match.

@@jacobspadt2567 I see it now, thanks!

There's a high-school robotics competition called FRC. This is a "robot in three days" team that made an example robot to inspire and help those FRC teams. This video is a prototype of a climbing mechanism, which is one of the challenges the teams are making a robot to compete in.

It's for FRC, a robotics competition where the game was announced on Saturday. High school teams have roughly 6 weeks to make robots that complete various objectives from the game. We try and make a robot in only 3 days to help get them started. It's more useful than your comment

For Inspiration and Recognition of Science and Technology

It shouldn't since our climber doesn't touch where the hole is, that's what the circle is there to show

We have a hole under the metal plate but since our cage is made out of wood, we wanted to help teams by adding a thin aluminum plate to show how the friction between the hooks and the plate would work. When we tested it without the plate, and we did have a few issues with the hole at the bottom of the cage, especially when one of the hooks would go through the hole rather than stay at the plate, it would not be able to push off. To resolve this, it's essential to provide sufficient spacing between the hooks, ensuring that the actuator makes contact with the sides of the hole and stays aligned with the metal plate. By doing so, the hanging mechanism will be able to push off from the plate consistently, allowing for secure engagement .

The majority of us are college of engineering majors, but we have members in at least 6 of Penn State's academic colleges.

The drive NEOs don't get stalled so they should be fine, and the climb NEOs are only used a bit at the end of the match. Teams have been covering their swerve drive modules with PLA for years, so it should be fine

Check out our climb showcase! ruclips.net/video/IP6gVlijUuI/видео.html We ran a 225:1 on two neos.

Yes, the robot was 105, but we had to add 30 lbs of ballast to get the cg right. With weight saving design choices and consideration of CG the robot would be under weight.

Interesting. Do you happen to have the rule number for that?

⁠@@jacobspadt2567rule number?

@@jacobspadt2567i thought you could only have/touch the coral OR algae

@@vortexgaming7364 Rule G409 says you can't have "more than 1 coral and 1 algae". As long as you have one of each, I think you're in the clear.

Thank you! No sensor, just eyes, both intakes are run on a button push. On outtake of coral no input is needed for L2 and L3. With more time we could have tuned to passive outtake to work on L4 as well.

Check out our donut climb showcase! ruclips.net/video/IP6gVlijUuI/видео.html We are lifting the robot with two neos on a 225:1 ratio.

they’re prototyping, this is nowhere near a final product

This is for FRC. This is an Ri3d robot (robot in 3 days), where teams attempt to build a robot in, well, 3 days. There are competitions, but the teams in these competitions are high school teams, which usually use the entire 2 month build season to make their robots Regarding quality, they are prototyping and testing, and they also have 3 days to make the thing. They don't have time to do it well

Far enough my apologies

We hung our deep climb cage 3 inches from our carpet, with better balance (no tipping) we expect to have 3 inches of clearance from the ground after climbing. We don't think a small height difference would alter our design.

PIDf control and setpoints. I highly recommend looking into it, learning proper PID tuning can greatly improve a robot without the need for additional sensors (if you are using brushless motors)

@@aristeinfeld3687 Yep! We use a PID loop with feed forward to quickly and consistently go to different positions on our elevator and wrist. All of our code is available on GitHub as well! github.com/Ri3D-PSU/Ri3D-2025

The tilt of the two intake motors is an unintended consequence of adding a horizontal piece of surgical tubing to increase compression force. There is a lot of flexibility in how those are made and we believe the effectiveness would be similar with correctly fabricated vertical motors.

@@PennStateRi3D Oh lol. Thanks anyway, the surgical tubing also sounds interesting as a way to improve grip.
