OYES Robotics competed as an independent team in the VexU World Championship last week. We were able to take home the VexU Robot Skills World Championship with a score of 121 points, the VexU Programming Skills World Championship with 47 points, and the VexU Excellence Award.
We were knocked out in the semifinals in part due to a series of unfortunate events, so our robots never made it into the dome. I thought I would make a reveal thread since I think we took some pretty cool stuff to worlds which a lot of people didn’t get to see.
24” Robot – Master and Puppet
4 motor 1:1.6 drive (Two of them…)
1 motor 4.375:1 lift (Two of them…)
1 motor 5:1 claw (Two of them…)
Flat polycarbonate tether (almost impossible to entangle with)
Able to block both goals at once
Able to manipulate large balls and buckyballs
Almost impossible to beat (unless our other robot disconnects for the last 15 seconds stopping us from hanging… ) https://dl.dropboxusercontent.com/u/39516124/OYES%20Reveal/IMG_20140417_193706.jpg
Orion was designed mainly for skills. Master and Puppet with Whiplash was supposed to be the combination we used for elimination matches, but Whiplash’s drive train was notorious for shearing motor gears and 36T high strength gears, so Orion could be converted to 15 inch size limit to take its place.
A few trivial points which may (or may not) be of interest:
Best robot skills score in practice (2 robots, 30 seconds) = 129 points.
Best robot skills score in practice (1 robot, Whiplash, 30 seconds) = 78 points.
How to complete the final (and winning :)) programming skills routine at Worlds which previously was not hanging within time = increase drive motor power values, accept that accuracy will be somewhat hairy and cross fingers tightly.
All robot names inspired by Metallica.
The boys were still still doing skills runs at 10:00 pm prior to packing the robots and a 4:45 am wake up to catch the flight to LA!
A few more thank you’s:
To Steve and Connor 2915A and Nick 2915C for providing tough match practice in the lead up Worlds. Congratulations to you both on the great results.
To Jack and Steve’s Mum and Dad for all manner of awesome things, including creating the shroud for Master & Puppet and for putting up with our boys for a week!
To Kevin Li (formerly WASABI) for helping out at Worlds. You are a true professional. (Loved your reaction on the M&P game video :D)
To Jack, who is one of the most positive people I have ever met.
To everyone who volunteered at Worlds, especially for the VEXU comp. It was a magnificent event.
I only have a couple of others (I’m sure Lucas probably has some on his account too though).
Occasionally we would try a 1 minute robot skills run with 1 robot just to see where we stacked up against high school teams - here is one by orion (approx 112 points) https://www.youtube.com/watch?v=9LBFhovrc64. And another early season run by Whiplash in november (99 points) - but with a “fake hang” - this was back when it had a 6 motor drive and 4 motor high hang instead of a low hang however it wasn’t attached when this was filmed - [https://www.youtube.com/watch?v=7_Fnhggr99I

I’m afraid I dont have any really exciting videos to release (I mainly just have older lower scoring skills runs) but this one might be a laugh:
This robot was so frustrating to program autonomous for… Not only are you writing two autonomous routines at once, but the tether is dragging both sub-robots off course constantly AND it takes a full 2 minutes to actually set the robot up at the start.
