【Training Camp】The dog carrying a "bazooka"

Overview

Introduction:

Main control chip: Huawei HI3861

Servo control: PCA9685

Servo: MG90

Dog body: a suitably sized cardboard box

Dog Legs: Ice Cream Sticks

Firmware: Modify the original firmware provided by Chuanzhi to basically realize all actions on the web page control

Power supply: I didn’t buy lithium batteries. I happened to have a few supercapacitors on hand. I used four 350 Farad supercapacitors (bazookas on the back of a dog, hahaha) to supply power in series. Advantages: Charging is super fast. Disadvantage: too little power.

Existing problems: 1. Hongmeng programming is indeed still in the "Hongmeng" state; 2. The accuracy of making dog legs with ice cream sticks is limited, the gait is not adjusted well, and it is a bit mentally retarded to walk.

================================================== ==================Separating line============================== ========================

The following is modified on July 21:

1. Drawing on the dog legs drawn by the PCB painter, I bought a few PCBs from Lichuang and replaced the PCB dog legs. The accuracy of the dog legs has been improved;

2. After learning Deng Ge’s pineapple dog video on bilibili, and adding the gait algorithm, the pace has been significantly improved;

3. The three supercapacitors on the back were replaced with six (two groups connected in parallel) 750 Farad lithium-ion supercapacitors. The three super rocket launchers became six small-caliber rocket launchers, and the total weight was significantly reduced;

The attached application mainly modifies dog.c and genki_web_ohosdog.c, and kinematics.c modifies the dogleg parameters.

Help with one-button power on/off solution for embedded devices
Hello everyone: Previously, I designed a one-touch switch using LTC2950, which is a key switch. The key press time can be controlled. It is used to manage the power supply circuit and is completely in
