What are the available obstacle avoidance technologies? Minimum depht based on the ping sonar? , Anti-collision laser Vs floating objects (boats, buoy, tree branch, vertical obstacle). etc.

Hi @DanP  
Welcome to the forums!  
In short, not much! [ArduRover](https://ardupilot.org/rover/docs/common-object-avoidance-landing-page.html) has some information on the subject in their [docs,](https://ardupilot.org/rover/docs/common-simple-object-avoidance.html) but I’m not aware of anyone using this so far. A lua script to re-route when ping sonar depth is less than some amount would be pretty cool!
