[Training Camp] Robot dog based on Hi3861

At the last moment, I finally completed this project. The control panel design was relatively easy (there were only two large pieces in total), but the assembly was a long process.

The acrylic kit cut by Moubao actually had several legs when it was received! ! Contact the merchant for reissue. . . It was reissued three days later, and it took a week for the cut parts to arrive.

When I bought the servo, I bought 6 of them because I had two at home before. The new one and the previous one were both made of nylon gears. However, after installing them, the original servo gear had missing teeth and would often get stuck and spin wildly. Kill me

After many adjustments, I finally solved the problem. Currently, the legs are fixed with screws, not glue, so they will fall down when they move. I will adjust the posture when I have time, and then use glue to secure them before recording a video.

The main control of this kit uses Chuanzhi Education's Hi3861 Hongmeng module. This module inherits WiFi. For the first time, you need to connect the module's WiFi to configure the network for the module. After the module is connected to the network, you can perform network control and OTA through the LAN.

Okay, let’s start with the pictures

Also: If you have money, don’t buy a servo with nylon gears! ! ! !
