【Training Camp】A Single Dog Makes a Dog

Overview

"Dog Making Diary"

The project was approved on June 20.

On June 21, I drew a circuit schematic diagram.

I drew the PCB diagram on June 23rd.

The review on June 26 has not yet passed.

Hitting the board on June 29th

Welding on July 10th

Try debugging on July 15th

Assembled on July 18

During this period, I encountered a magical thing, that is, Gouzi actually has a CD cooling period, and is only allowed to debug once a day. Once the power is cut off and reconnected, it cannot be moved.

Product introduction: Using HI3861 and PCA9685, it can support 16-channel servo control, and can realize the functions of the mechanical dog such as forward, backward, left turn, right turn, etc.

Double-layer board design, single-sided layout, free proofing by Jialichuang

Components cost about 50 yuan

There are 8 servos and one Jialichuang express box. The 3D printed dog legs need to be enlarged about 11.2 times to fit the M3 screw lock hole.
