【Training Camp】Robotic Dog

Overview

Introduction: Robot dog using OpenHarmony system

Product introduction: Developed based on the OpenHarmony open source Hongmeng system. The chip used is hi3861, which supports 16-channel servo control, GPIO, ADC, PWM and other operations. It has realized the mechanical dog moving forward, backward, turning left, turning right, lying down, etc. Function, reinforcement learning will be supported in the future. (mpu6050 needs to be expanded)

Application scenarios: Can control robot dogs, small spiders, servos, gimbals, robotic arms and other products, supporting up to 16 channels of servos

Chip solution: multi-channel steering gear control board based on HiSilicon Hi3861 chip and PCA9685

Product core parameters:

Working voltage: 7.4V~20V with overheating and overcurrent protection

Hardware interface: gpio, ADC, PWM

Double-layer board design single-sided layout

Total material cost of the complete set: 165~300 yuan

pcb: Jialichuang free prototyping

Components: about 50 yuan, pca9685 is currently out of stock in Lichuang Mall

8 servos (7.2 yuan each for a certain treasure) + PCA9685 (more than 10 yuan for a certain treasure): 70 yuan

Dog body structure: Acrylic cut version (about 20 yuan)

3D printed version of the three-dimensional monkey (about 100 yuan)

Others: M2.5 screws, anti-slip nuts and some self-tapping screws, about 10 yuan. 7.4V lithium battery: 15 yuan.

(The steering gear screws are all provided, 12 M2.5*10 screws, 12 M2.5 anti-slip nuts, 4 40mm double-pass posts, 8 M3*10 screws, 8 M2 .5*7 screws)
