such a good idea!! I totally AGREE!!!!!!!

u find them?

they look like some sort of lego wheels

yeah, the time to switch was last year

Yep! The kit that we are using has been kindly provided by the Gong Invaders from when they were competing a few years ago.

@@UnqualifiedQuokkasRi3D cool

its not just the weight tho, its also how far out they put the intake to offset the robot CG

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.

On our intake, we are using the REV 30mm traction wheels and for the drivetrain we are using 96mm gobilda mecanum wheels.

Our linear extension is the actobotics linear slider kit.

@neutron1996 ty man I really appreciate it 🙏

dont get this kit, in fact you cant anymore, i would recommend belted viper slides and using that in the same way that they use this.

@hypocritical7379 oh ok, ty man really appreciate it

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.

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 [email protected] 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.

Absolutely! We plan to release a tech binder breaking down our design as well as robot CAD sometime in the next couple of days.

@@UnqualifiedQuokkasRi3D Awesome! thank you so much 😊

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.

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.

I mean, come on. These robots 🤖 r gunna have a claw or ingestor. Most robots will have almost lot in common.

Then they don’t have to post it

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.

They look like tiny Lego wheels, but I may be wrong

Hi, the wheels are 30mm Traction Wheels from the starter REV kit :)

Oh thanks

What's bad about spintake?

@@acursedhope I personally just dont have much good experiences with spintakes, too finicky and unreliable for me, but im pretty sure thats just me

@@2_Kan ah gotcha, that's fair

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.

I don't see any reason why not, at most you may have to worry about which side the clip is on, but i find that unlikely

No, just riveted gusset plate. It may be one piece in the CAD because it was faster to model.

Allen Bradley 42JT-F5

@@kayrunjaavice1421 how can we buy it? or can you send me an alternative link on rev robotics site? Might be distance sensor?

@@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.
