VIDEO:
VEX Team 8468 Nothing but Net Double Puncher - China Ürümqi No.8 High School
I already posted this on FB VEX group but I’m gonna post it here too 
“This is really exciting cuz my friend who is in Ürümqi, China (Team 8468) send me this video about their well functioning double puncher!!!
The way they did it is absolutely amazing and I’m just in love with their bot right now!”
Attaching file is a detail pic and even with that I can’t figure out how they did it 
Any ideas?
Wow, that design actually worked quite well 
Dual everything ftw
Very interested to know how fast and accurate it can go…
Nice Design!
I was thinking the same thing!
Most shooters in wisconsin that have the pluggers can shoot three to five balls a second with just one. They don’t shoot that fast during a match because they have not come up with the loading mechanism like this robot. So I think this team should be able to shoot all 24 matchloads in 4 or less seconds by the end of year if it is even possible for a person to load that fast.
I am just more impressed with the intake getting all four balls at once.
Impressive! Is there a reason why the highest (not counting the allegedly illegal 287-point score by 2527A) Robot Skills score from Wisconsin is only 105? With robots shooting up to 5 bps, that should leave at least 40 seconds for collecting and scoring field balls, after shooting all 64 match loads in around 13 seconds, and leaving up to 7 seconds to drive between the two loading zones. Unless these shooters are just incredibly inaccurate, they should be scoring at least 250 points, with 40 seconds to score field balls.
I love it! Go Ürümqi! Go!
As a team in Wisconsin myself (and have attended all tournaments so far this year) i have seen launchers that are very fast and can launch at that high rate, but once they reach that high speed, they become horribly inaccurate, therefor they do not run that fast in tournaments. team 2527A was truly a VERY good robot and launched very fast and accurately, despite the miscommunication of rules to them. They won both of our Wisconsin tournaments so far. Basically, teams have not been able to control their high speed launching and have yet to develop intakes fast enough to feed that fast of a launcher, and they do not want to sacrifice accuracy fro speed, as we are all still working on our fine tuning (5bps is still a goal all of us are a little ways away from reaching! sure, some launchers can, but those balls wont make it to the high goal, and if they do they wont make more than just a few accurately!)
I am assuming that you are talking about 5 balls per second from the loading zone, as many teams (including mine) have achieved over 5 balls per second from shorter distances.
Yep the Wisconsin teams i have seen have yet to achieve a 5 bps rate for full court shots that i am aware of. My team can launch all four balls in our intake in under a second, a probably five if it was legal to hold that many, at short range for full court shots? thats a work in progress for the teams i have seen. Many have the capability, but a little more programming and fine tuning and i think they could do it well.
