Robot uses UDP for all media traffic (audio, video, and driving commands) instead of TCP.
Why UDP?
- Speed: UDP is a "stateless" protocol, making it much faster for real-time communication.
- Low latency: Unlike TCP (used by YouTube or web browsers), UDP does not waste time re-sending lost packets, which prevents lag during a call.
Note: Because UDP discards erroneous packets rather than fixing them, poor network quality will be immediately visible as brief "glitches" rather than long pauses.
