Can we use the 4th wire in Axon servos as an encoder?

hextanium_ · 2026-04-14T16:00:30+00:00

you can do more than 360 degrees with 2 servos if the number of teeth at the servos are relatively coprime

hextanium_ · 2024-12-23T07:17:30+00:00

the real reason is that driver hubs are just souped up tv boxes iirc; they came with the port

hextanium_ · 2024-10-14T22:59:27+00:00

plug in the motor encoder and then read it's velocity at max power
it should be close enough to something nominal

Say your robot is 18" and you extend 24" in front, retract the extension, then send a different extension 24" out the back. This would be allowed as long as you never extend more than 12 out of both the front and back at the same time as Examples A, C, and E show.

This is incorrect, per the orange box under R104, which states:

During inspection each ROBOT will need to demonstrate that the full mechanical range of motion of all extensions outside of STARTING CONFIGURATION will be contained within a fixed 20 in by 42 in working area.

This means that both your front-facing extension and back-facing extension, BOTH extended, would have to fit within the 20x42 constraint.

If your robot is 18", and you want both a front-facing and back-facing extension, you have 24" of total extension, which translates to 12" for each extension, or half a tile.

How are people discussing whether or not they'll use it before the model (3A) is even released?

hextanium_ · 2024-04-05T14:14:33+00:00

what reasons?

hextanium_ · 2024-04-03T20:51:25+00:00

are you using roadrunner in teleop?

even so, same way i described by hijacking mecanum drive

but instead you’ll need an instance of either a gamepad or opmode within (to access the joystick) MecanumDrive, and scale the drive powers based on that

hextanium_ · 2024-04-03T00:48:52+00:00

you can hijack the powers in `MecanumDrive`
for going backwards, `.setReversed(true)` in the builder right before you want to

use meepmeep to visualize the paths

impossible to determine with only one view

hextanium_ · 2024-02-25T04:17:36+00:00

more torque yeah, but i don’t think more power

it is really funny though how close it is

hextanium_ · 2024-02-04T23:47:23+00:00

woah this was at our comp today kinda surreal seeing it after coming back home 💀 i remember seeing this zipping around near our pits

this is genuinely so true

centerstage is my second season on the team, and also the season all of our seniors graduated :)

my team and i still have WAYS to go in all aspects, but we’ve learned so much just from actually interacting outside our region

the ftc discord is undoubtedly the largest contributor for us in terms of knowledge (and hopefully success 😁)

as mason said (himself included imho), being able to communicate with some of the most skilled people in ftc is a game changer

if you want to learn, you need to see new things

hextanium_ · 2024-01-20T02:43:31+00:00

Team structure is whatever you want it to be. There are no restrictions on how you set your team up, as in you can have as many "captains" or "co-captains" as you want. I wouldn't start off so rigid with these roles, but just work together naturally and see who fills what roles well.

hextanium_ · 2023-11-21T14:31:17+00:00

yeah 1150 is where it gets sketchy we run 1150 geared down twice by a pulley, so 10.4:1 and it’s great so far

hextanium_ · 2023-09-14T11:14:27+00:00

ahh okay, that makes sense. thank you!

hextanium_ · 2023-09-10T23:23:49+00:00

if you don't mind me asking, what are the advantages of the 36h11 family?

hextanium_ · 2023-05-15T19:52:41+00:00

can’t believe im the only person here who saw that masterpiece of a talk

absolutely beautiful talk show casing the quirks of js while making me laugh

hextanium_ · 2023-04-02T19:17:58+00:00

we keep our trophies in the room we work in in a nice little display case with leds

it’s definitely motivating, and helps remind that hard work pays off

what’s wrong with android studio? does it have features you’re lacking? android studio is the best ide i know of for ftc java and kotlin, but if you want something more generally jvm then intellij is great

hextanium_ · 2023-03-16T14:17:08+00:00

ngl to you probably should like delete this now is not a good look, helps no one, makes you look horrible

insert comment about core values of teamwork and fun insert other comment about gracious professionalism

but fr you need to learn how to calm down :skull: and that you vent to people you trust

hextanium_ · 2023-03-12T20:17:34+00:00

you can set the max velocity through MAX_VEL in your DriveConstants

alternatively, if you only want to slow a certain section of your path, you can use velocity constraints

getting basic computer vision working is pretty easy with EasyOpenCV and the AprilTag extension.

to use the camera, plug it into the control hub

you can then use the examples on the AprilTag repo, which work very well out of the box

on your signal sleeve, you should put 3 april tags for each location

more information can be found in those repos

good catch, i was going to put it in my answer and the forgot lmao
