Overview

Disadvantage

A Hongmeng Roaring Heavenly Dog. Too fat, too fat

describe

The bionic robot dog based on Hi3861 has four dog legs driven by 8 servos and has functions such as walking, obstacle avoidance (ultrasonic ranging HCSR04), tracking (infrared sensing), and buzzer sound reminders.

The expandable gyroscope MPU6050 can adjust the dog's body posture;

The Qiyingtailun C1122 module can be expanded for voice control.

0.96" OLED display can be added.

During the design, it was found that the PCA9685 in Lichuang Mall was out of stock, so I used the PU9685 module (supports IIC and UART) instead, which is available on a certain treasure store.

body structure

Based on the example project, a non-proportional expansion was carried out. A dog head has been added, does it look like an alpaca, or more like SpongeBob SquarePants?

[PS, as the volume increases, the weight increases, and the load increases, will it not be able to run:( :<]
