What is the swivel joint screws that you use in a lot of the moving components that look to be attached to stand offs. Our team can not find anything like those in the vex v5 materials? Those would be very helpful to our design?
Unrelated to the intake but I wanted to ask how you got the shooter of your robot and such angled so nicely. I know their are angle pieces, gussets and hinges and probably other ways you can angle things but it looks like a lot of your structure just involves shaft collars, screws/couplers, spacers, and standoffs. Did you just use these to angle the top portions of your robot? I've never seen this done before and I'm relatively knew to robotics and thought it was interesting, also would you consider a video going over general structure/chasis of your robot or of robots in general?
yep! by using shaft collars, we are able to achieve non-standard angles by using triangles with custom lengths on each of the sides. By changing the lengths of the sides of the triangles, we are able to adjust the angles of all the mechanisms on our robot. The shaft collars act as vertices of the triangles because of their ability to rotate as well as attach standoffs to them. Generally, the same can be done with C channels to form triangles to get custom angles as well. Many teams use this to get desired angles on flywheels, roller mechs, etc.
@@606X Wow that's a really cool way to structure a robot. I wasn't even aware screws could fit through shaft collars before I saw your robots structure. Unfortunately it's too late for me to make much use of this info with my current robot though I am using it with my pneumatics and end game now. Thanks for the great videos man.
heads up those 15 tooth gears y'all used are discontinued, so if a judge recognizes them they might dq. They almost dqed us, but it was a new and not very popular rule so they let it fly.
Why is it so easy for your robot to pick up disks using 2” wheels onto almost a vertical polycarbonate? We always get stuck at the around 80 degree angle.
try reducing the initial angle of the ramp, and moving the first stage of the intake further forward from the ramp. We found that these two changes helped a lot for us
@@606X Yes, I agree, but then the length of the robot has to increase. Your 2" flex wheels almost touch the polycarbonate. I feel something else than the two factors you mentioned also plays an important role.
This is our judges interview presentation
Wait you can give people video links during interviews and stuff? Or like show them the video?
No we were kidding
Been struggling with our intake for a week and nobody is willing to make such a helpful vid thank you so much!
I was experimenting with that kind of tensioner for the floating intake but I couldn’t get it to work. Nice job :)
I appreciate this video so much
best intake this season ong

very nice build

Where did you get the polycarbonate sheet used? I can't find many that are less than 0.070" thinkness. Thanks.

compitition is going to be tough this season...
What do you use to program?
Could you guys explain how you make your intake floating and how you made sure the chain wouldn't skip?
Cool! What inch size flex wheels do you use?
3 inch and 2 inch

Good
You got the CAD for it? If so can you give to to me so I can look at it better? I'm Trenton Williams From 19197A, The Technical Titans
how did u attatch those small flex wheels?
How did you link the standoffs at ~90 degrees for the floating intake? It looks like a shaft collar?
shaft collar + standoff coupler + standoff
@@606X I didn’t know they had couplers :0
Thank you 🙏

What was the reasoning for having the system using flex wheels rather than a chain with the rubber flap things?
more grip, more compliance. the tank flaps don't have the suitable level of grip on the discs we were looking for.
hey, I noticed that you are aiming the vision sensor down. What is that for?
we were planning to use it for automatic disc sensing. we didn't finish it in time for mall :(
It's so he can look down on his weak opponents lol-zies 😂
did you dye the 15t sprocket to be red instead of gray?
No they're originally red, dyed to be black
15-tooth sprocket is crazy 💀
Me and my bud wanna remake this so we gonna do our best hope you don’t mind
how did you dye your intake wheels, it looks so clean
we put flex wheels in a pot of boiling water with dye. the flex wheels dyed after 2 minutes
@@606X thank you
Why did u switch to cata?
Our intake
you can turn it around tomorrow trust 🙏
We hope so, so many controller problems
Whats the point of the intertwined zip-ties on the "antenna"? might use something similar for this year.
Smoother sliding when the disc goes along the antennae path
did you use 1/32 or 1/16 polycarbonate sheets
1/16
@@606X thx
is there anything special on the poly carp to make it less frictioned?
Sanded with 800 grit to make it smooth
oh thanks, how much effect does that have on the friction?
@@46bvexrobotics65 it's smoother than regular polycarb. i can't really quantify how much but it does feel better.
Anyone know what size the grey flex wheels at 5:23 are?
2", 3", 4" from the bottom going up
What are the Omni wheels under the robot for?
they're odometry tracking wheels
@@606X Ok, thank you
What's ur drive RPM?
360 rpm 3.25” wheels. Our drivetrain video covers this more in depth
What are the flex wheel sizes?
watch the video
Is it legal to use flex wheels?
Yes
