Interesting Crank Lever Mechanism - Part 1

This is a simple crank rocker mechanism that originated from a video on Facebook. Let's create it using blocks!

Assembly Steps:

▼ Materials for the imitation millstone section.

▼ Construct the rotating part imitating a millstone.

▼ Create the handle part (remember to use a bearing where rotation is needed!).

▼ Next, assemble the puppet part.

▼Ha! A rather peculiar-looking figure.

▼Strike a pose!

▼Attach the puppet~~90% completion. Once you add the battery compartment, you can give it a test run!

★ Scientific Principle

1. Linkage: The component that connects the crank and the rocker, enabling the motion between them. It is referred to as a linkage.

2. Crank: A linkage with a fixed axis capable of performing a 360-degree rotational motion. It is called a crank.

3. Rocker: A linkage with a fixed axis that undergoes a specific angle of oscillating motion. It is referred to as a rocker.
