[Unitree Go2] Access to Microphone

Sensors
1

Hello,

I’m using a Go2 EDU Plus with the expansion dock (Jetson Orin NX) and need to capture audio synced with the robot’s motion.
I need to capture acoustic data through the go2
Is audio recording accessible via built-in microphone from Go2?

My questions:

  1. Does the Go2 EDU Plus (with expansion dock) have a functional onboard microphone that is accessible to the user via SDK, ROS2 topic, or any API?
  2. If so, what is the correct method to access/stream/record from it (e.g., ALSA device name, ROS2 topic, ffmpeg/PulseAudio configuration)?

Robot info (if needed for your reference):
Model: Go2 EDU Plus
SDK: unitree_sdk2py

From my experience, the microphone is NOT accessible. But it is very simple to attach an external microphone to the jetson carrier board and access that for your recording controls. The speaker inside of the main robot body, however, is accessible.

What are you trying to record? I have programmed my GO2-EDU to execute all of his sport moves (sit, wave, pounce, etc) using voice commands.
