Why not make a climb like 973 2022? Just a slightly angled elevator to grab onto the first bar then have an arm that when you swing into the second bar you release from the first. You could also have something like 1678 2022 but that’s a little more complex
The plan was to have the CoG directly below the first set of hooks such that your chassis sits parallel to the floor. This then allows for the maximum shift as the arm it extends out. We can also extend all the way out to the limit. Unfortunately we didn't get a chance to test it out fully integrated with the bot, but the idea was to get it to a stage where the concept was fledged out enough that teams could take it and make it their own. If we were competing this season, there are a number of things we would be doing differently, which we will be adressing in our tech binder. So keep an eye out for that on our Instagram and Chief Delphi thread for when we release that in the next 24 hours.
Thank you! That was definitely one of the main goals of the intake. We wanted to be able to slam the intake into the tiles and quickly extend it at a group of samples and always have one end up in our control.
still a little confused on how yalls intake works, does the wheel wdge the block in between it and the polycarbon flap or does it work differently? either way brilliant design
Yep, that's exactly right! We had plans to possibly add a roller underneath to assist with some slight height misalignment, but given the time constraints, it ended up working well enough that we didn't go further down that path. We plan to release a tech binder of sorts some time in the next couple of days discussing our process. It will have a more in depth breakdown of the intake and the other mechanisms there, as well as improvements that we identified but didn't have time for.
@@UnqualifiedQuokkasRi3D Thats really cool to hear! My team was considering something similar but we were planning on using a container instead of sorts to house the specimen I'm currently looking for feedback on my design and I recently made a CAD, would yall be interested in checking it out? We still haven't received game pieces yet so it's hard for me to gauge whether designs will work or not
@@Darkcamera45 we would love to! Send us an email at unqualifiedquokkas@gmail.com and please CC a mentor. We will check it out and can answer any questions or concerns you have about your design, or about our design too.
Would you all be willing to share the CAD for this robot? I really like the active intake/deposit and I want to get a closer look at it as I had a similar Idea
Surprisingly, the small REV wheels were quite grippy. That, in addition to the pressure applied by the slightly compliant polycarb plate underneath grabbed the samples very effectively.
Hi! I really like your guys's hang system, but I'm trying to understand how you're able to achieve this with the motor limit of 8. Where are the motors being distributed, and with the current distribution will your bot be able to complete a level 3 hang?
Currently this robot has 4 motors for driving, one for pivoting the arm, one for extending and one for climbing to the first stage. For the stage 3 climb, we had a number of different prototypes, some which only added one motor and some which added two, but removed the motor used for the original climb.
It is a very tricky challenge indeed. We had 2 concepts that didn't work, and a third that kinda did. I believe we will be discussing them more in our tech binder that we hope to release in the next couple of days.
so cool to see yall working with ftc! member of frc 1317 here we were really inspired by your design last year and its great to see yall again this year helping with ftc!
We use Actobotics X-Rail slides. The kit we are using is quite old, and the Actobotics product line has been discontinued, but there are similar products from goBILDA and REV.
HELP, i've downloaded the intake shooter. stp and when i tried to open it in solidworks it crashed. Is there another version of this you can post? SolidWorks perhaps?
@@catdogin I'm not sure you can get it at a reasonable price anymore because it was included in a kit of parts a while ago. Check out beam-break sensors instead, they might get better consistency than the sensor we used and are very cheap
Its an AB 42JT-F5 and we chose to use it because there was no other option on-hand. It is not ideal for this applocation and a longer-range sensor or a beam break would be more consistent.
This robot is incredible. The way y'all were able to think out of the box in just 3 days is admirable. This robot will undoubtedly serve as inspiration for many teams robots this year, just because of how clean and elegant it can be, while accomplishing everything so well. I cant wait to see what y'all do over the next years with your Ri3D bots, because this is nuts.
Awesome work! Asside from the climber, this is exactly the design my team came up with in our initial brain storming at kickoff. We're still working through more itterations, but will probably still end up with something similar
How does your intake work moving at faster speeds. Does the wheel design consistently intake the game peice exactly when you touch it or is their inconsistentcys like bounceing off the intakd
In our extensive testing, we never found the game piece to bounce off the intake. We have 2 rollers, the top is able to grab the game piece and suck it in, then the bottom roller sits just behind that and kicks the note up off of the ground and into the intake.
This is amazing! How do you guys think the shooting mechanism would work if the vertical gray wheels were swapped with horizontal flywheels? Did you do any testing that could show higher reliability or distance?
Due to the time limit, we basically built the top and bottom roller shooter, it worked well, so we ran with it. We didn't do much testing with horizontal flywheels, one or two tests, but they weren't anywhere close to the effectiveness of the top and bottom shooter. Looking back on it, this was because we didn't compress the game piece enough to increase the contact time. Having the top and bottom flywheels also meant that the construction of the intake/shooter mechanism was extremely simple as it only requires 2 side plates to be manufactured.
@@UnqualifiedQuokkasRi3D Okay, that makes a ton of sense. My team really loved you guys design and are using it as the basis of our robot (we're gonna make further developments, of course). We will probably do some testing with horizontal flywheels and rollers with different compressions. Thank you so much for posting your designs and helping teams around the world! -Team 404
