WAVEGO (EU) kit for building quadruped robot for Raspberry Pi - Waveshare 21781

Description

WAVEGO is a bionic dog-like robot. Equipped with high torque servos 2.3 kg*cm, it has a reliable structure and devices such as front camera, 9-axis motion sensor and RGB indicator. It uses the ESP32 module as a slave controller to solve inverse kinematics and generate gait. An additional Raspberry Pi can be included as a host controller to implement high-level functions such as image, motion, and color recognition.

The multi-joint design has 12 degrees of freedom, and the applied algorithms significantly increase the effective torque of the servos. It is made of an aluminum alloy and PA12 nylon, which, with the use of 40 sets of bearings, ensures durability and lightness of the structure.

Built-in precision 9-axis motion sensor ICM20948, adapted to different terrain conditions, maintains stability thanks to the self-balancing function.

The set uses a camera with a resolution of 2 MP. The robot is controlled via a web browser thanks to an automatically generated Wi-Fi hotspot. It does not require environment configuration, it allows you to connect and log in to the website without installing the application.

The kit includes a holder that allows you to mount a Raspberry Pi minicomputer, which can be connected as a host controller and communicate with the auxiliary controller via UART. The ESP32 module is responsible for performing computing tasks and generating gait, so they will increase the performance of the Raspberry Pi to perform high-level functions.

The ESP32 module is located on the base board. The user will also find a power circuit, PWM driver, IMU sensor and flash memory on it.

Full documentation with numerous examples is available on the product page.
