Waveshare WAVEGO 12-DOF Bionic Dog-Like Robot, Extension Pack
Features
The WAVEGO is a high-DOF bionic dog-like robot which features 2.3kg.cm large torque servos, reliable structure, and 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 sub controller for connecting rod inverse solving and gait generation, sharing calculating task for the host controller, an additional Raspberry Pi can be attached as the host controller for high-level decision operating.

1. Overall 12-DOF, multi connecting rods leg design, increasing the servo effective torque
2. A real time operating system is used as sub controller for connecting rod inverse solving and gait generation, sharing calculating task for the host controller and improving the gait solving efficiency
3. Ultra compact structure design, allows using on the table, aluminum alloy + nylon structure materials, ensuring strength while keeping it light weight
4. Additional Raspberry Pi can beattached as the host controller to enable OpenCV high-level functions, demo codes including facial recognition, motion detection, color tracking, and more. Reserved extension interface for secondary development, along with user manual and secondary development documents.
