Australian 4613 Robot Reveal 2016!!

[Type]

Great robot! What wheels are you using for the shooters? And what motors are you using? My team is using 4" Stealth Wheels ran by mini cims, geared 1:1.67 with 3" of compression. We are having issues shooting so we may change the gearing again.

We are using 3.5 inch Colson wheels (hex bore), driven by 775pros with 4:1(5:1 originally, but 4:1 gives a faster launch speed) Versaplanetary gearboxes. 9mm belts and pulleys are used to transmit power from the gearbox to the shooter wheels, so the Versaplanetaries can be located behind the shooter wheels.

They may be 4:1 now.... 5:1 wasn't quick enough

Another zig-zag bumper design. Seeing more and more of them. Brando was singing their praises a few years back... ...yet another new trick for this old dog to have to learn...

It never ends with this FIRST stuff. You have to keep watching, keep learning if you want to stay on top of your game.

FYI, my favorite part of this year's Behind the Design was the great pains that Vince & Stephanie went to pull tricks of the trade out of their submissions and reveal them to the mere morals like you & I.

Zig-zag bumpers. Keep an eye out for them. They look like a lot of work. But a lot of smart teams seem to think the work is worth the bother.

Cheers,

We'll see how it works out soon! Hopefully it wasn't a waste of time...

The zig-zag components of the bumpers, were manufactured on a CNC router. The pool noodles, were happy to conform to the shape after a bit of persuasion and restraint. The most complicated and time consuming component was the fabric. A lot of time was spent trying to prevent creases in the bumper fabric.

As Josh said, only time will tell whether it was worth it.
