Here is a link to a new video that I just posted introducing the AREDN controlled rover. The rover was 3D printed with PETG plastic on a Creality CR-10s Pro printer and has a Raspberry PI 3B+ with Python code. The on-board node is a Ubuiquity 2g XW Bullet (what I had left over in the parts box). Roving range is mesh range. Control is provided by keyboard commands via Putty with 30 second safety time-out from last key stroke (no input for 30 seconds = all stop) should link go down or excessive latency. On-board camera provides the FPV via web browser.
