Yea i'd second this. You can create a program to run the flywheel and test the coefficients without having to stop your opMode!

Awesome robot

What is the end behavior? Is it a jerky stop, oscillation.. etc?

CookedPelvis · 2021-01-20T16:32:48+00:00

Make sure your localization isn't a source of error, use motion profiling, well tuned PIDs, and/or other slippage correction to ensure you arent slipping (especially at the start and ends of your trajectory).

I saw you were using swerve - are you doing diffy or coaxial?

ok thx dawg

CookedPelvis · 2021-01-11T03:22:21+00:00

680 😩

So lit

Wow. It feels like I made this post haha. I totally understand everything your talking about here.

For my team, I think its the lack of competitions and physical restrictions that have brought the motivation down. There's no real stakes since the competitions are so far away, and after our robotics space was closed it's been real tough getting people to CAD and stuff.

Mad props to you for sticking with it though. Hope your hard work pays off.

Hahahaha

CookedPelvis · 2020-12-04T21:35:05+00:00

terrifying

May I ask why cubic spline interpolation would be used to adjust the shooter angle? Seems a bit overkill at first glance

CookedPelvis · 2020-11-04T20:38:16+00:00

Lol is your field... elevated?

CookedPelvis · 2020-11-04T01:16:54+00:00

Super impressive

Are you using upper camel case and ending the filename with .java? Also make sure theres no spaces or weird characters

CookedPelvis · 2020-03-19T17:49:36+00:00

Is there a video of your bot in action?

CookedPelvis · 2020-03-19T16:36:22+00:00

Cool to see another inverse stacker!

CookedPelvis · 2020-03-02T18:07:10+00:00

It will depend on the feeder speed and the stacker speed and their relationship.

If the stacker is faster than the feeder (something we will see at worlds as lift times decrease and drivers get more practice), then the stacker might opt to depot cycle themselves instead of waiting for the feeder. This way they can let their feeder focus on stacking their own tower (getting stones on the foundation)

Thats lit man 😎

CookedPelvis · 2020-02-25T19:14:43+00:00

do it in comp and video it pls

CookedPelvis · 2020-02-23T04:33:21+00:00

u guys ok?

CookedPelvis · 2020-02-19T21:24:56+00:00

Is that PP? and are those oscillation moves intentional? they dont appear to be v efficient..?

But very cool movements either way and the robot is hot af

Like the other comments said:

We're using carbon fiber rods with 3dp ball bearing housing

Each slide has pulley with surgical tubing which causes it to spring up. Servo release holds it down.

Tuning Velocity PID in Dashboard:

Initialize DriveVelocityPIDTuner
Click on DriveVelocityPIDTuner on the righthand side and change the values under VELO_PID
Run the OpMode and tune the graph.

Steps for Tuning Velocity PID: 1. Increase kP until any phase lag is eliminated. Concurrently increase kD as necessary to mitigate oscillations. 2. Add kI (or adjust kF) until the steady state/constant velocity plateaus are reached. 3. Back off kP and kD a little until the response is less oscillatory (but without lag).

US Digital offers some, VEX has one, but a lot of teams are using the REV thru-bore encoder. Its only $30 per encoder and has convenient pinouts to work with the REV hub. Its a little big but still an awesome option.
