【LiChuang Training Camp】Bionic Robot Dog - A Devilish Dog

Introduction: Robot dog using OpenHarmony system Product introduction: Developed based on OpenHarmony open source Hongmeng system, the chip used is hi3861, which supports 16-way servo control, GPIO, ADC, PWM and other operations to achieve some simple actions. Chip: Multi-way servo control board based on HiSilicon Hi3861 chip and PCA9685 pcb: Free proofing by Jiali Chuang. Components: About 50 yuan, be stable when welding, otherwise you will have to spend more money. Servo: MG90S is recommended, which is better. (I bought sg90 just for cheap, it was slipping and couldn't move, and the screws should be carefully screwed, otherwise it would slip) Dog body structure: Use acrylic cutting, only 14 pieces. Others: You also need a lithium battery of 7.4-12v. You will also need 12 M2.5*10 screws, 12 M2.5 anti-skid nuts, 4 40mm double-pass columns, 8 M3*10 screws, 8 M2.5*7 screws, and M2.5 anti-skid nuts.
