Purpose

While I am browsing the website, an interesting Chebyshev connecting rod structure case comes to my eyes, which are used to simulate the walking of the robots.

Thus, I am going to a walking robot with our bricks and Nezha inventor’s kit.

Bricks assembly

If you have Lego studio app, please download this file: The Walking Robot.io

After assembly, install the motors and Nezha Nezha expansion board with the bricks.

Software Programm

Step 1

Click “Advanced” in the MakeCode drawer to see more choices

For programming, we need to add a package: click “Extensions” at the bottom of the MakeCode drawer and search with “nezha” in the dialogue box to download it.

Notice: If you met a tip indicating that some codebases would be deleted due to incompatibility, you may continue as the tips say or create a new project in the menu.

Step 2
