We have two quality entries in, and 26 hours to go (10 PM here in rainy Delaware).
So break out the VIQ parts, or slap the GeForce RTX 4070 Super GPU into you CAD box and get building or designing your entrie. You have the time, you have the skills, just gotta jump on it and go.
Bragging rights for your robot team, not to mention some Cool VEX IQ parts. .
This robot (read the Hitchhikerās Guide to The Galaxy if you donāt understand the reference) is a PTO dual cata with adjustable intake. Since actual pneumatics are hard to get in the CAD software Iām using, I used the blue shock absorber part ( It may be a little wonky since it isnāt the exact length, etc. ) for pneumatics. Rubber bands were also left out on the intake rollers.
This robot boasts several things:
It has no 2x at all except 4 2x4s which could be easily substituted (in light green, supporting the PTO assembly)
It has an adjustable intake that moves down to intake the balls fast and moves up to let the cata fire
Fast 1:1 winch catapult with pneumatic release (standoff connector and green gear are supposed to be a Short Low Profile Pawl and ratchet gear)
Gravity gear PTO between cata and intake allowing for a 4m 2:1 drive with INSANE acceleration, especially with this lightweight build
Triangles for light but strong bracing
As with the other CAD entry, there are no cables or pneumatic tubing/other pneumatic elements
Techniques in the quote below were also applied
Thanks to Mr. Schucker for organizing this contest because it allowed me to explore lots of innovative building techniques that actually may be useful for competition since they reduce weight while still conserving build strength, and a happy New Year to everybody!
Nice job, very, very nice. Your note says it has the pneumatic release, could you have done the release like is in Swish? That would save you the weight of the tank and the cylinders.
On the first view there is a light green 1x2 used to tie the 1x uprights together. Since corner parts are āfreeā you could use a 2x Wide, 2x2 Corner Connector or a 2x Wide, 2x3 Corner Connector at that joint (and the one just above) to make it a little more rigid. But an excellent way to finesse not having 2x beams.
I also like the use of the long axle parts to keep things tied together from side to side.
The use of the PTO is pretty interesting idea, if I get some time after Sugar Rush Iāll try to make it.
You are very welcome, Iām very pleased with all the entries. There have been a few other very successful contests. I love the Clawbot II one that produced the "Octoclaw" as an entry. There were also some great 2019 entries to the Lunar Lander competition.
Still a few hours to go before the deadline, lets see those final designs.
The judges deliberated over night and the decision is
@3apples was the winner with string bean. The design is great, the construction is well done and it works since they actually built it. (Iāve used CAD to design things that at the end of the day just donāt work, but the drawings look very cool). It also made me smile that it was scraping the bottom of the parts bin to find usable parts.
@10673, with their Heart of Gold Mk II robot is second. I love that there is a lot of complexity there, but is still using 1x beams. I do wonder how it will do with the catapult and the light nature, will momentum not be itās friend?
@RoboticsIsFun is the third place winner, but it is the robot that Iām going to build. It looks like it would be approachable for a novice builder to construct since it has a much simpler design. The simple block setup to make it work really helps.
was the original plan, but with the close nature of the two CAD designs, Iām going to bump the third place prize to $75. If the three of you can contact me at foster at S T E M R O B O T I C S dot org, we can work out how to get you the parts.
Thank all of you very much for your time and designs, youāve inspired me to start pushing teams to build differently. An hopefully youāve inspired other roboteers to not automatically reach for the 12x12 plates.
I got the latest design from Ben Lipper in my email. Impressive design, and it looks a lot like 2 of the entries in the contest. Wonder if he was inspired by the 1x robots.
