 I learned about how FIRST really is about so much more than a robot competition, it is about team building and the individual. - Adel Hodiwala [more] |

Our drive base for 2010'
6 wheels, center wheel lowered ~1/8"
4 Cims to 2 toughboxes to Six 6" wheels
The center weels will be replaced with AM-"plaction" wheels.
Climbs the bump very stable after hours of tweaking the frame.(hand pushed)

I am curious - what made you decide to build such a small chassis? (looks to be no more than 22" long, and ~20" wide).

Hmmm...It looks like Florida will have at least one tunnel traveler. Looks good guys, can't wait to see the rest

Are you only going to be powering 1 wheel per side or have not run the chain for the rest?

Look close, you can see sprockets on the outside of the end wheels, which will likely be used to connect them together with a long chain.
6 wheel robots usually work better with all 6 wheels powered, though.

I'm more interested in the contraption behind the table. Care to describe it?

Looking further....it appears the center wheels will be driven directly off the toughboxes, from the other of the double sprockets. Neat design.

That square looks just like mine, rust and all. I'm gonna have to check my garage and see if it's still there!

I know this isnt the finished chassis but I would seriously consider beefing up the rear part of the frame where you have the cutouts. By removing the legs of the channel it will want to bend at that point. Perhaps look at putting a belly pan underneath the entire chassis out of 1/4" baltic birch.

Or since the chassis is rather short, just patch on an 1/8" doubler plate to the outside of the chassis around where the cutout is. My bigger concern is that they appear to be sharp corners and not radius cuts. Sharp corners will be a potential source of failure in the part.

all six wheels will be powered, we just did not have the sprockets in stock at the time lol

we just bolted a 1/8th alluminum plate to the bottom, we also will have a super-structure to tie everything together, and it will also be completely welded*
not only will it go under the tunnel, but it Will climb the bump
