Sorry to the three gears I destroyed, your sacrifice will be remembered. Thanks to Ben 515R for recommending me to thin gears using a lathe. Thanks to Joey 4082B and Tyler 4154V recommending hacksawing.

are the other wheels necessary or is this possible with a standard x dive?
Hey what are they shaft call , which has perpendicular mounting hole, can i get a link to buy for same?
Thank u,I tried this way and the screw blended 3 weeks later ,maybe my robot is too heavy, how can I solve this problem
high stakes before it was high stakes
Can you do a tutorial on it? I would very much love to learn how to do this as I'm new-ish to software
its been a while but how do you know where to box, should u just pick random positions?
box structural connections i.e standoff to metal and metal to metal. things that don’t withstand stress don’t need to be boxed
@@ryan4253b i see, is it fine if i use a standoff for screw boxing on the top instead of another hex nut
This is the reason smaller programs die and other schools will not get involved.
what's that box on the x drive?
How is this done? I am trying to run something and make it stop while the drivetrain is moving
Check out how to use multithreading. I have the lift and chassis run in separate threads so they can run at the same time
How do you get the gif on your screen?

Do you have any documentations or recommendations on how to implement this myself?
i want you

Damn bro quite the lunch been having it for months now
Teach me
Is that an FRC field in the background 😮
yup
would a dnc be better than a PID in terms of accuracy?
Or you could just select it in your controller just saying
Controller input is disabled for any stage before driver when your controller is plugged into the match control system. You can technically write another program to select in driver control then write the results to the file, but that’s another project for someone else to complete.
@@ryan4253b or before you connect the controller in to the match cable, you select and run the program.
you using a inertial sensor to keep track of the rotation?
yes you can you can also use the gps sensor
@@user-wo9pj8dv8qhow would you use that?
Brain explanation video?
Legend says Ryan is still not back from lunch
How did u screw joint them
just want to make sure those 7/8 spacers are vex legal right? from mcmaster
they are legal
How do u do this
when u screw joint on the red gear do u drill a hole through them so it fits?
On the HS gears, just use a circle insert.
Promo-SM ☹️
Great stuff, Ryan! Keep them coming!
Can we get a laser cutting video next?

common ryan W as per usual
hi ryan
Solid
nice
Ryan’s videos are the music I have in the background
ryan build quality master fr
W vid
nice, we'll have to try it with the harbor freight mini lathe that we have
Just watched a couple of these, great job
I understand the original vex gears had them, but is there a reason for the protrusions on each end of the gear not being cut off completely? Removing them would create a flat profile on both sides, though to be fair I'm not sure just how much more usable that would make it and there might be a cost in structural integrity trying to break the inner metal insert of the gear. Additionally, can this be extended to the steel pinions and 24T gears?
You would cut into the metal core
Well, the main reason here is what with this mounting method, it is impossible to fully flatten out the gear face. The lathe would otherwise go through the screw and the gear would likely be damaged in the process. You can flatten out the center using a belt sander afterwards - this would work as long as you do it in short intervals to make sure the metal core don't heat up and melt the plastic. As you have said, it is somewhat rare where you will need a gear that doesn't have the core intact - you can build a 3 wide drivetrain with the core, and I've personally never needed a gear where the entire face needs to be flattened out. Leaving the core also benefits from the extra stability and the ability to use the new shaft inserts. This method would also work with steel pinions and 24T gears. Just make sure to go slowly and apply oil as you are cutting through steel instead of plastic.
I'm new to VRC what is the best use for this?
you prolly alr know but makes your drive so much better and easier to build
better free spin for wheels also better joints
This is egg chair privilege.
Amazing
go to bed

man i needed this
Can the chasis become out of square over time? If so, how would you go about fixing it?
Yes, the chassis can become out of square over time. As for a quick fix, loosen all the bracings and align the chassis using shoulder screw and 5 wides again, then tighten the bracings and remove the 5 wides. It is however easier to ensure that misalignments don't happen in the first place by having a well structured and supported robot. Note that this technique also applies to structures outside of the chassis. Here is a pic of me using the same technique to square my robot's towers. cdn.discordapp.com/attachments/594335615361875991/1129425104695218276/IMG_5487.jpg
that’s so cool bro
Everyone needs to watch these videos 🗣️🗣️
This series is great for bringing your robot building to the next level, and I really appreciate you sharing these tips.
Thank you I love you
