Pics of the Linkage-Steered Cubmobile

Here are 2 real pics and 4 presentation pics that explain our design fairly well.

WOW

THAt's some pretty neat artistery. Kewl design. Very original.

That "artistry"... hahahah!... was not because I'm any good at art... it was screen traps of a 3D CAD model I used to get the geometry worked out on the car.

Did drawings too of the piece parts... about 17 drawings of 19 piece parts, not counting parts list I did by hand to save money (just buy exactly what we needed and not have more than 1 extra of any particular nut or bolt was my goal, came darn close to perfection that way).

Laid out the parts, cut them, drilled them, and assembled first try... worked great!

I don't think I could dig a hole in my yard without first modeling it.

I don't think I could dig a hole in my yard without first modeling it.

I'm the same way!!

I hammered large nails into the outline of our driveway to measure points (triangulate) and laid it out in CAD to calculate the square footage to make sure I wasn't getting ripped off. 2 of the 3 companies were within a few percent, 1 was 30% high (rip-off!).

What CAD program do you use??

I dont see the hand brake. I was wondering how to brake this car with the lever in the way?
I also dont see the stop blocks. That would disqualify it in a lot of Districts.

Its great to see some ingenuity anyway.

I bought a 'student edition' copy of ProEngineer a few years ago.

The handbrake is fairly visible in the "real" photo... didn't have it in the CAD model when I took these snapshots, although later I added it.

The steering stop is in FRONT of the steering input bar... once again I didn't have it modeled yet...

BTW, just last night my son was tooling around the street on it, and I removed the steering block for him.
It was never needed in the race, as he actually had control of the car instead of a safety catch for when he lost control... the whole need of steering blocks is what caused my initial concern with the classic cubmobile design... if the steering is working properly, why do you need to limit it to nearly zero?


Have a look at the "live" pic closely, you'll see them.

I forgot about these being handy, have a look:
