Hello comrades. We’ve worked very hard on this robot and finally completed it to competition standards. Also we’ve already changed it significantly so a new one will be coming soon. Let us know what we could improve on.

Base: 2 motor 6 wheel H Drive
Intake: 2 motor, 3 level rubber band spinners, connected by chain to two front wheels
Catapult: 2 motor 1:7 with lotsa rubber bands
“Swiper” (To remove caps from posts): 1 motor 1:7

Swiper has been updated to get both heights of posts.

Do you really need a 1:7 gear ratio to knock off caps?
I thought they were pretty light?


#3

you can knock them off with a 1:1 393 motor

Ok, uhh… a few things ->

  1. By H Drive, I assume you mean tank drive because you can’t do an h drive with 2 motors.
  2. Why exactly did u guys chain the intake and front wheels together? (i guess that helps with climbing) but those wheels don’t even touch the ground, you could just build a 1 motor intake and a 3 or 4 motor drive with all motors adding to the overall power of the drive instead of 2 motors driving wheels in the air adding nothing to the drive since the intake only needs 1 motor.
  3. With v5, you guys should be able to easily do a cat with only 1 motor, you don’t need 2
  4. You really don’t need a 1:7 ratio for the descorer, 1:3 or 1:5 should be sufficient.
    Hope this helps and sorry if you’ve already implemented any of these.

Does the catapult only work with one ball?


#6

The catapult works with two balls, but we weren’t able to make it accurate enough to hit both before the video came out. For the swiper we used a 1:7 because we wanted to extend the arm to hit the top posts and that wouldn’t have worked with a 1:1. Not exactly sure why we decided on that size but that’s the way it’s built. The catapult was working with 1 motor but the 1 motor seemed to die way before even time for 1 match, therefore 2 motors


#7

How about a 1:3 or 1:5? I think mine is 1:5, but it’s a bit overkill in complexity.


#8

We might decide to go that 1:5 route because the gear seems to be getting awfully close to the catapult
