Hello guys, we’re SJTU from Shanghai Jiao Tong University.
We’re glad to share our robot to you.
Good luck and enjoy the game in this seaon.

Is that carbon fiber I see 
Really, nice build! This is what we like to see from Vex U competitors

brilliant engineering going on here!
I love the actuating intakes and that discarder design is very clever.
fantastic robots!

Love some actuated intakes, and everything is so clean! Great work!

Yes, black ones are made of carbon fiber

That’s a great discarder! I’d been messing around with one like that in August but I’ll have to try again after seeing yours

Brilliant design. Love the ingenuity in the discarder (and how you have like 20 of the same bot lol)

This is amazing. I do have to ask one question though. Is there a single vex part on that robot?

V5 motors lol
The flex wheels for intake and omni wheels are from VEX EDR and VEX pro

Wow. Just saw this and I love it. Very clean discarder.
I love the extra control and durability of the intakes allowing different methods of cycling out center goal.
This. Is. Awesome.

That’s great. I see a rubber band going over all the horizontal bands on the top roller. Is that so that the balls will want to go to the middle instead of out of the sides, due to the hourglass-shape in it? If so, That is a really good Idea.

This is really interesting.

Brilliant discarded. Now just time to figure out how the heck I could do that.

You could always ratchet it to your flywheel
the discard involves the flywheel trying to score
If the flywheel is weighted enough it will continue to spin during the brief time that the motor reverses to trigger the discarder, especially if it’s a smooth ratchet. done right it could be op
edit: you could even combine it with a pooper and have two different ways of discarding which could be helpful for advanced match programming down the line

i must say that this is one of the most advance VRC robots that I have seen so far… ever since OYES VexU robot.
and they made full use of the flexibility given to VexU teams. Well done!
PS… i have been telling my teams many times before - it is possible to 3D-print the entire robot!

3D-printed materials make the design very flexible, but it’s more fragile than metal, and they’re really easy to be broken in a fierce match because they’re a lot of hollows inside like a beehive.
Hence we brought a lot of back up 3D units to the World Championship.
If you increase the compactness, it will take much longer time to print and increase the weight

Think the choice of filament will be the most crucial over here?
but that will also indirectly means that those teams that can afford better 3D-printers will have a competitive advantage.
