Any thoughts?

Looking good.

Is that Alex’s voiceover in the first video, telling you not to do something stupid?

A “been in FIRST too long” moment, if you can ID the voice behind the camera.

3

Looks good guys nice work on the crab.

Planning on doing anything with the orbit balls? :stuck_out_tongue:

Hope to see you guys in competition.

4

Looks like a fun drive train.

Are you going to support the drive modules anymore than that? They don’t look like they’d be able to withstand a large side load. (Pushed Sideways on Carpet edge)

5

That sure does sound a lot like Alex.

6

indeed it is :smiley:

7

Looks pretty cool, have to see how well that will work in competition this year with the trailer attached

8

yeah, hopefully something a bit more sophisticated than just bulldozing the balls around >_<

9

yeah there will be more supporting it, if im not mistaken we were are flipping whats on top and what is on bottom, so the electrical board will be on the bottom and there are slots for the Crab drive in the Frame the electrical board is on.

10

Ahh… That makes much more sense. It just looked as if you were just going to leave them as they were but that additional framing should protect them some.

11

Your robot looks pretty cool :smiley: Best of luck!

12

BALLIN!

wish i was there today…

13

Looks like you have a FP motor into the AndyMark planetary on at least 1 crab module. What made you guys decide to use FPs for your drive??

14

They prolly need a CIM for the ball launching/collection mechanism… that’d be my guess.

15

I was more asking why they used a FP in the drive train because of power issues. I understand that we are in a different world this year with the wheels and the floor but i still wouldn’t use a FP as my main power for a drive train.

16

So whats going on here is that we have Windows on Turning, CIM’s on our 2 front wheels and FP’s on 2 back wheels. the reasoning is that we need 1 CIM for shooting and 1 for intake.

17

its actually 2 windows and 2 globes on turning

18

So, if I’m not mistaken, you have 4 steering motors and 4 driving motors? 4WD independent swerve is always impressive. Have you tested it out on the slippery floor material yet?

Great job.

19

very cool drive train…hope it works well in competitions!
Good luck !

20

have you tried turing the wheels sideways to stop faster yet?
