I asked a while ago if anyone has ever tested a lidar underwater but didnt get any answers, but it turns out they do work.
Really cool bit of engineering in that little submarine!
Very cool that the LIDAR seems unaffected by the acrylic (or polycarbonate).
I have always wanted to build a sub, il get around to it one day.
I had thought about it before since I have a waterproof lidar (the tfmini plus), but I never got around to actually placing it in water.
