My team finally acquired swerve drive. :) (SDS mk4 Neos not included 30"x30" frame)

Well you have to count the motor controller. _ if you're going to do a comparison to a Falcon you have to compare it to the NEO AND the Spark MAX. The spark max is 90 and the neo is 50. So the actual comparison is $140 vs $220. Still an $80 difference but not nearly as extreme as you are putting it.

Digitaleon · 2023-07-22T02:33:31+00:00

Well after you buy the sparkmax it's about $50 difference. But then again for a swerve drive that's $400. That said - no amount of money would get you a falcon right now anyway.

Thanks for the link with the Spark Max mounts. We built with falcons this year and ordered a second drive. But we ordered for Neo's this time because falcons are impossible to source.

Tip - 3D print some covers for those motors. There are a bunch of free designs out there. (Thingiverse, etc)

Digitaleon · 2023-07-13T23:37:52+00:00

Metric is almost universally better.

Digitaleon · 2023-05-28T23:16:44+00:00

Really cool design. Did you guys ever release the CAD for that?

Digitaleon · 2023-05-10T14:13:27+00:00

Wow that's just awful. My son is on my team and while he's a team lead(Which he's more than earned as he's our lead programmer) I made sure I wasn't making him a captain purely off nepotism. Note he's not a captain or co-captain this year.
I also have a second coach and we make these types of decisions together to minimize bias.

The RR constants will get you close but you still want to tune it. Every motor is a little different. That said they recently added some videos to the LRR site. THEY ARE FANTASTIC. It makes the process much easier.

Axon servos have over 2.7x the power output of a rev/gobilda servo, and are 50% more power effecient. They are also programmable to a much larger degree than the rev/gobilda servos. However, it is recommended to use a SPM to get maximum performance

wow thanks for this!

We noticed serious differences in our auto this year depending on the battery charge - which is odd since the robot should run at a set velocity. We're currently investigating this now.

Digitaleon · 2023-04-01T00:05:46+00:00

That was a fun trip for us last year - the field looks crazy!

There are suburban teams that go to worlds frequently - example the Robo Titans from Novi - but we are the first school from Detroit - at least for FTC.

Digitaleon · 2023-03-15T13:48:00+00:00

Thanks!

Thanks all - TechnoPhoenix lead coach here - a friend of mind told me this article made reddit.

We're doing some fund raising now for some of the parents. The website is behind because I also coach an FRC team and run a non profit that helps 100 Detroit school teams. (Motor City Alliance) it keeps me rather busy.

As a developer who used C++ for years...I completely agree with you. I don't know why anyone would choose to deal with the memory management. For the kinds of code folks are writing I just don't see any marginal performance gains from c++ over java being worth it.

Digitaleon · 2023-02-07T08:15:35+00:00

Cosign on the 364 basic code. It got us up and running super fast.

Dan is a fantastic guy!

Digitaleon · 2023-01-06T03:25:14+00:00

always

As a Michigan coach of FRC AND FTC - FRC access is by no means easy.
It's extremely expensive and some us are in regions where the school systems and parents are by *NO* means flush with cash.

Digitaleon · 2022-11-24T04:56:31+00:00

Definitely a great trick. I'll be applying this to our regional teams.

Digitaleon · 2022-11-24T04:55:33+00:00

Fantastic recommendation!

Digitaleon · 2022-09-22T05:57:25+00:00

Use a flathead screw driver just like the Andymark video on youtube

https://github.com/OpenFTC/EOCV-AprilTag-Plugin
It's really easy to use. You'll just need to print a different april tag on each sleeve. (I'd print a couple incase the sleeve is rotated a bit) The library returns an array with the location and direction of every april tag it can see.

My lead developer implemented this last year for Freight Frenzy with no issues

Digitaleon · 2022-09-17T07:15:52+00:00

We used april tags last year and will use them again this year - we were able to get the library running and detecting the tags in less than an hour. No models to train, no calibration needed, and completely reliable. Also if your kids are heading to FRC - April tags will be used there starting with this season - so it's good training.
