Devlog 3 : Magazine and shooter
Hello guys! This time we have most of the robot done, time for an overview!
Magazine
The Magazine is based off a rubber band design, this way we have compliance so that we do not have to spam wheels.
If you look in the photos, you can see a set of blue and black wheels, those two are connected by rubber bands.
Addressing one of the concerns in my ship: The balls should not fall out. since the ramp has a hole in the center ideally the artifacts should self center and the rubber bands should hold it in place (Something I have personally seen on a real robot).
I also faced another major problem, how do I get my artifacts from my mag to my shooter?
Due to the form factor of my build needing a turntable, I can’t just directly send it straight into the turret, as it wouldn’t reach without adding like 50 rollers. (large rollers would collide into my turntable housing) So i devised a counter roller, which is mounted in the rear and can speedily feed things into my shooter! (this is shown in the 2nd slide image on the bottom right, look for the 2 sets of black rollers near the green ball)
Shooter
I decided to go for a turret, although several teams have had major success in a straight shooter (shoutout to my goats 30564). This was because I felt that shooting on the move and shooting no matter where we are is what makes something competitive, and it also is a test of my cad skills.
I took inspiration of the Andymark turntable, but the form factor wouldn’t work here, so I took the bearing and put it on a custom plate.
For the turret itself, its a single 6K rpm motor, which from my previous experiences was more than enough, we also have a Limelight (vision camera) on the shooter for accurate localization.
