Waveshare WAVEGO Basic Version 12DOF Quadruped Robot Bionic Dog Robot Dog Open Source for ESP32

Description:
The WAVEGO is a 12-DOF bionic dog-like robot that features 12 x 2.3kg.cm large torque servos, reliable structure, flexible motion, incorporating devices like front camera, 9-axes motion tracker, RGB indicator, etc., together with open source multi-platform Web application. It uses the ESP32 as a sub-controller for connecting rod inverse solving and gait generation, sharing calculating tasks for the host controller.

Features:
* 12-DOF, more flexible movement.
* Multi-link leg structure + inverse kinematics algorithm, increasing the servo effective torque.
* With ICM20948 9-axis motion tracker, self-balancing mode can be used.
* 2.3kg. cm high-torque servo, the locked-rotor torque is up to 5.2kg. cm, and it is more extensible.
* ESP32 is equipped with an OV2640 camera, which can realize low-latency image transmission with a 2.4G external antenna.
* It is composed of 5052 aluminum alloy and PA12 nylon parts. There are 40 sets of bearings used in each joint of the whole body, and the structure is firm and reliable.
* Integrate a variety of interactive devices, including a 0.96-inch OLED screen, two RGB-LED indicators, an active buzzer, etc.
* The example code is developed using Ar-duino IDE, no need to manually configure the compilation environment, ESP32 will automatically establish a WIFI hotspot when it is turned on, you can use a mobile phone (for Android/iOS) or computer (for Linux/Windows/Mac) to connect and log in to the control page, just need to install a Chromium-based browser, no app is required.
* With a charging interface and automatic download circuit, you can use it during charging.
* Onboard two series 18650 batteries, 5200mAh in total (2600mAh for one battery), larger output current, and more powerful servo.
* Onboard lithium battery protection circuit, with anti-overcharge, anti-over-discharge, anti-over-current and short-circuit protection functions.
* The onboard INA219 acquisition chip is convenient for real-time monitoring of battery voltage and charging current.
* 2*5P expansion interface is reserved for the remaining IO and serial port of ESP32. The functions include RGB expansion, RX0, TX0, G21, G15, G12, 3V3, 5V and GND, which can be used to communicate with the host computer or connect to other devices.
* As the lower computer, ESP32 can share a lot of computing power of the rod inverse solving and gait generation.
* All codes are open source and provide online rich development documents and tutorials.
