Flat Car: Part 10 - All Done

Friday, August 5th, 2022

The prototype is assembled and functional!

So many improvements need to be made: it needs to be flatter, more responsive, more durable. But I’m very happy with how it turned out.

My original design brief: I have a desire to make a motorized “car” that can be as flat as possible. I want it to slide under a door, flip open, and drive away. I have a very cinematic vision in mind, I see a spy, or cat burglar, or techno supervillain using it. Not that I want it to be used for nefarious purposes, it’s just something stuck in my head, so I’m going to make it.

One of the main advantages of using FR-1 as the main material for the car body is it could also be the primary circuit board for all of the electronics.

Flat Car: Part 7 - Sliding

I figured sliding under the door was going to be the easiest problem to solve, so I saved it for last. I tried using a bunch of different types of caster and roller balls. They worked great but ended up being too bulky and unnecessary.

When the wheels are flattened, I have the car resting on 4 small screw heads. It slides just fine.

Flat Car: Part 6 - The Sloan

I redesigned the flip mechanism. Meet “the Sloan”.

After discussing some possible designs with my friend Sloan, we came up with a release lever concept.
The hinges were replaced with spring load hinges.

And each motor has a release lever that locks into a new wheel design. When the motors turn, the lever is released.

More to come.
