 We are happy to present you our integration of the Unitree Go2 with ROS2 over Wi-Fi, that was designed by the talented [@tfoldi](https://github.com/tfoldi). You can explore his groundbreaking work at [go2-webrtc](https://github.com/tfoldi/go2-webrtc).
 
 This repo will empower your Unitree GO2 AIR/PRO/EDU robots with ROS2 capabilities, using both WebRTC (Wi-Fi) and CycloneDDS (Ethernet) protocols.
