Apex Robotics Team 5803 is proud to present our STEAMWorks entry: HAILSTORM!
Featuring a fuel capacity over 60 balls, a single wide shooter and active funnel system that can sustain a 7 ball-per-second rate of fire, active ground gear pickup and placement and a 4 second climb from catch to trigger. Its twin MagiKarp is also pictured.
Apex Robotics is sponsored by AeroTEC LLC, The Boeing Company, Oak Harbor Freight Lines, C4 Labs, Concept Systems Inc, WestCoast Products LLC, First Tech Credit Union, Washington FIRST Robotics, Alaska Airlines, Prism Graphics, Friends and Family of Apex Robotics & Seattle Christian School.
We will be competing in the Pacific Northwest District Events at Auburn Mountainview (Week 1), Mount Vernon (Week 3), Glacier Peak (Week 4) and hopefully the PNW District Championship and the Houston Championship.

The scouts on the Sonic Squirrels will be really excited when they see this reveal vid. Can’t wait to see you guys at Auburn Mountainview and Glacier Peak! Going to such a stacked Week 1 event is going to be crazy enough, but on top of that, our second event will be Apex and Skunkworks’ third event.
The gear intake roller is a three layer rubber sandwich. The core is 1.25" ODx 0.5" ID polyurethane tube (McMaster P/N 87235K82). That fits nicely over 1/2" hex shaft as a drive axle (this is what we used for our boulder intake last season). We shoved latex tube over that (McMaster P/N 5234K91), but this was almost entirely to cover up a mistake where we thought the urethane was 1.5" OD (oops :rolleyes:), so I don’t think it’s really a key part. Over the top we wrapped Moisture Sealing Electrical Tape from home depot, which is basically rubber tape. That’s really nice because if it wears down at all we can just replace the tape.
Thanks John! Our parents and students work really hard to make good bumpers. Just like our practice robot, our show bumpers are our practice bumpers that we use to figure out the build order and any nuances. Especially this season since we aren’t doing one-piece bumpers, this was very helpful.
With a single speed, single reduction transmission, going 8WD allowed us to optimize space usage by putting the gear train in the box tubing and the chains on the outside. Every single decision on this drivetrain was made largely to minimize space, including chains over belts, 6 MiniCIMS vs 4 CIMS (though there are other benefits there too) and single speed.
With space at a premium this year, we like the decision.
Really proud to be a part of this team! Everyone has worked so hard to make this year a great one so far! Excited to see these students compete, it’s gonna be an exciting year!
Do I have permission to show this robot to people who say “but we can’t ever compete with those teams that have 6 waterjets and a $1,000,000 budget”? Nice job, love the feed to the shooter.
Absolutely, please share away! We couldn’t do what we do without the great COTS options available. This season we’ve been fortunate to have some limited CNC capability from two of our sponsors: AeroTEC machined the 1/4" plate on our shooter, gear intake, feed rollers and magic carpet. C4 Labs let us run their CNC to cut the gussets that connect our shooter tower, and Bear Metal 2046 graciously machined our drive rails. Everything else was cut on table top tools shown in our video.
