I looked at a few designs but settled on the Tilted Twister because it only required 2 servos to operate, which wasn't as complex mechanically as other robots such as the Cubestormer.

So here's how the mechanism basically works:

1. A platform holds and rotates the cube.

2. The arm pushes and holds the cube.

When I first tried to build the solver, I tried to follow building instructions here:

But I was pretty lazy and didn't follow the instructions, so I made a wooden replica with a few tweaks.

I haven't documented every step of the build process, but I think you can reproduce the tilted twister design with a few tweaks:

1. Slanted sticks to prevent the cube from snagging.

2. To build the arm joints,

- I drilled a hole into ends of the popsicle sticks.

- I cut out 2 cm of a wooden skewer.

- I inserted the skewer into the sticks

- Glued wooden wheels that act as washers on each end.

Honestly building the physical solver was a lot harder and complex than I expected, so if you have any questions on how I built the solver, just ask.
