Quadruped and its dog design (Doge) based on HiSilicon Hi3861

Production process

• Mechanical part

Official case: http://heimarobot.cn/blog/29 Whether you can win or not depends on your luck (it was always 404 a few days ago, but it works better these days        22.7.20 )

As for my design... at the official hole position, I abandoned the acrylic solution and used 3D Monkey from Jialichuang for 3D printing (the cheapest resin, the better quality ones are      slightly more expensive )

       In order to make the movement smoother, 2.5*5*1 bearing installation positions are reserved at each joint. Facts have proved that the wear is much less.

• Main control part

Hi3861+PCA9885

The current issues with board design are as follows:

1. In the 12V to 5V power supply part, the ldo is seriously overheated. The detected current is 1A, causing heat, so we plan to replace it.
2. The computer serial port of the CH340N circuit cannot be recognized. It is recommended not to add it. It is also more convenient to use the USB serial port downloader purchased by tb to debug (only connect TX, RX, and GND) to boldly carry out serial port debugging without fear of burning!
3. There is something wrong with the silk screen printing of the PCB servo interface and the position is wrong.
4. PCB size should be reduced, the dog can’t fit in it and will have to go bald~
5. Expand... I'm writing, I'm writing, I'm writing, I'm writing

• software part

Use the Ubuntu environment provided by the teacher and configure it! ! Just download a Clion and you can start developing~ Extraction code: qu2s

Except for the installation mode, all other actions of the officially provided firmware are in place . The firmware in the attachment is burned in the video, so you can eat it with confidence~

You need to customize the gait and access the relevant functions on the web page to modify the corresponding JSON string. Official video tutorial, learn not to eat the board
