Step 3Building the "tilt module"
The second module is the "tilt module". It's placed on the top of the "rotation module". Basically, we have a large gear (which doesn't turn) and a small gear which is driving around the big one. The gear ration is 1:10. That way, the arm can be more precise.
On top of this module there is a small platform, to which the claw is attached, but more about the claw later!
Attaching the two modules together couldn't be simpler. They are held together by a single shaft/axle, around which the "tilt module" spins. The arm can tilt for nearly 90 degrees, that's a lot!
