Reply To: Which radio link for a student search-and-rescue robot inside a rubble mock-up?

Went with 100 m of Cat6 on a reel for video and driving, and 868 MHz point-to-point LoRa for telemetry and the e-stop. The base laptop forwards to Hermetry. Pulled the tether out in a test on purpose and the e-stop still worked over LoRa. Judges liked the gas chart.
