Still not a fan of having to deal with SparkMAX controllers (or really any non-integrated motor controllers honestly), and a higher cpr encoder would still be neat, not gonna lie.
eh, the cpr doesn’t really matter once you account for gearing+backlash
I feel like integrating a controller into a motor of that size (or lack thereof) defeats the entire point, and there’s also some annoying physics things that happen (smaller bell diameter = less torque and etc from there), but as the masses shout, so they will have.
Depending on how exactly Vex implements the inevitable, there’s a hilarious constraint situation where not only does the controller increase the length, but you might have to add an extra planetary stage if that’s your gearbox selection.
True, but I don’t know if I’m adding an encoder at the end of my mechanism anyways, but having one integrated gives software the option to play around with it by default (also there are still some decently low backlash applications for smaller motors: flywheels, intakes, agitators, etc, where that could still come in hands, arguably some of the best applications for smaller BLDC motors anyways.
Yeah, smaller BLDC motors would be hella funny, but packaging constraints make using Falcons in certain mechanisms pretty painful, and the convenience of integrated motor controllers and (good) encoders, even with motor length taken into account, is still pretty hard to deny. Might not be perfect, but it would still be pretty neat in my opinion.
We used hex body rivet nuts to mount the modules on our 2020-21 robot, no complaints so far
After some changes and testing, our 2021 CAD and Reveal are ready to share! There are two files to account for parasolids being fixed.
Wow that intake is crazy good… we never got our viw version working half as fast. I’m guessing the pegs make a huge difference?
Hmm, you have passed the first test. Now make it fly, swim, and climb.
Skills challenge videos submitted. Below is a playlist of all of them.
That Accuracy video was painfully slow to watch but the scores are fantastic. Great work 2910!
Awesome stuff y’all, the robot looks absolutely dialed in. For sure one of my favorite 2021 robots!
Amazing work! Loved seeing Baby Grond do all of the challenges!
Glad to see someone else did one ball at a time for IA…I mean we thought it was a great strategy!
Beautiful robot. Loved watching these!
If only this were real. we are so tired of the sparkmax even though we love the neo550s…
I was going to reply with a complaint agreeing until I realized who posted this. I honestly think they’ll bring them in the coming years.
How does 2910 turn/lathe shafts? What machine do you use?
We use a cheap manual lathe and some knock off 12" digital calipers. https://www.precisionmatthews.com/shop/pm-1022v-pm-1030v/
Here’s the lathe, it doesn’t get too much cheaper
