Team 254 Presents: Dropshot

[billbo911]

Out of curiosity, what are you using for you vision tracking?

In this thread, Tom mentioned you had been having bad luck with the Jetson, did you end up using it, the RoboRio, or something else?
What camera did you choose for image acquisition?

I'm actually sure this is a swerve/omnidirectional drive and that there's no turret involved here. It's pretty obvious that the ball pickup is in the back, so if I had to guess I'd say that they use a pivoted roller to suck balls in from whatever intake mechanism they have (maybe the roller is combined with the intake too, I could see that) and then accelerate the ball linearly past those two flywheels.

Maybe a cheesy pof could check in here to tell me if I'm right?

My main indication that this is a turret is the extremely quick turning of the aim when it changes which goal it locks onto (at the end).
From my experience with programming and driving swerve, it would never change angle that quicky and accurately, especially while strafing.
Also you can kind of tell that the drive is moving in a tank-like manner.

The other reason is that 254 has a history of hating things that move sideways.

Thirdly, the 2016 game hates swerve.

Pure swerve at least.

After some reflection I do think you're right- at 20s you can see the black framing rotate with respect to the blue, which would only make sense with a turret.

16 doesn't count. I'm 90% confident they developed some sort of magical hover drivetrain years ago and have been making swerve to cover it up.

Now we know why there was no scaling pole on the castle tower.
Unless I'm missing something....

Also, Cheval and Portcullis? They could probably just ram the portcullis for a while if they wanted to get through.
Looks like they don't plan to focus on defenses though.

Edit: Looks like Mecanums might make their return to Einstein if 118 and 254 have anything to say about it.

According to their website, they are only weighing in at 94.5 lbs at the moment, thats easily enough weight to add something else....

[IronicDeadBird]

Woah that exit angle looks super low...

[tickspe15]

I see an unused bearing hole. Something's missing...

I notice you finally have blue clevises. Did you anodize the red ones you've used in the past or did you find a source for blue ones? The blue is a slightly different color so I'm assuming you found them somewhere.
