why can’t you get rid of the intake and use the claw to intake off the ground?

we did that in 2023 and it got hit once and the claw broke the rest of the event, doing a seperate intake allows for a safer way to pick up the coral without breaking the arm, and in the event the intake breaks, we can use the arm

reminds me of 3310 in 2023
there is a lot to like with the design and I’m excited to see what T3 comes up with this year!
I’m not a design expert (yet), but here is some feedback from my experience.
- This robot seems very complex. Are you sure you need to telescope the end effector? Especially after seeing how fast a kitbot on swerve can cycle, I don’t believe a lot of the design choices are efficient in minimizing complexity.
-
For ground coral intaking, I’d wait to see some more advanced centering mechanisms. It’s only day 2, so the designs are still cooking. it’s okay to be abstract with krayoncad, and leave room for future changes (we had a ground intake on our krayoncad but removed it before we did mastersketch). You can always just save a version and branch it as needed (I’m watching those Penn State folks; we may be able to design around their intake concept).
-
Understand that krayoncad is very arbitrary, and major design/packaging decisions are probably better to make in a mastersketch with real dimensions. This is a mistake I’ve made, and running based on a krayon can overcomplicate designs.
This robot design looks very promising! There isn’t a correct way to krayoncad, and your krayon drawing looks as good as any other I’ve seen.
Good luck in reefscape!

thank you!
if im gonna be completely honest, i’ve legit never cadded a robot and im only a sophmore, but i wanted to step up and i showed this to my team and they liked it. obviously we’re still gonna be working on the design as our deadline for starting CAD is saturday, and i can’t wait to see what you guys cook as well!

This looks exactly like 4795 from 2023:

you’re right lol, although i think a lot of robots this season will end up looking similar to 2023
As for feedback, I love the idea for coral. Makes it so much easier to pick the game piece up. When it comes to other aspects of the game (algae/climbing) do you have any more in-depth explanations?

the intake when lifted up should be able to grip the algae to score in the processor (although we haven’t tested it yet). In terms of climbing, we ruled out trying to do deep cage because we just don’t think that we would be able to do it, so instead we opted for a single climber to latch onto the bottom of the shallow cage. This should (hopefully) pull us up without touching the bottom, that is, if the tilt doesn’t just slightly touch the bottom
what was that intake made of?
it was just a really flimsy and poorly built telescoping tube, the arm was the intake for that season
Propotype the intake soon. I doubt the OTB portion will work well for pipes that are not in the correct orientation due to having no method re-orient the pipes before taking the tight turn around the bumper.
Also, I would strongly advise against rotating telescoping arm. Telescoping arm is taking elevator and shoving it into a smaller package than it wants to be in, losing significant stiffness while being hard to design. Adding it onto a pivot will further decrease stiffness due to backlash and wear, and problems with this joint are one of the primary reasons most telescoping arm implementations are bad. An elevator will get you the motion you want, but is much easier to design and much stiffer.

Your scoring mechanism should ideally shoot the coral onto the pegs, rather than have the arm place the coral and then release. A handoff for a complex is also not advisable, and I question the necessity of a ground intake at all. Coral fall unpredictabely, so any time saved not waiting for the hp will be lost lining up with the coral, as well as having added complexity
I wasn’t convinced with ground intake on day 1, but you should consider that the coral can be rolled towards the robot because there is a slot on the side of the loading station, and then the human player can forcefully push the coral using a second coral to make it roll farily far. This saves significant time, especially when the opposing allinace tries to play defense, as a defender trying to block the rolling strategy is at significant risk for penalties due to the coral falling into their robot.
i like the design, i assume your going for a shallow climb
Do you have any video of doing this consistently? We dont have coral station to play around with consistently putting down coral in control fashion. Even then the real field with practice field is always different interaction.
Not yet, people haven’t built the loading station yet. But even then, the field surface shouldn’t significantly effect how a pipe rolls.
See this like video for how coral going from the coral station and carpet interact. Cranberry Alarm did a good demonstration of this. https://www.youtube.com/watch?v=B3tjnM6YFOM
