Robot or laser to check on buried pipes?
I am looking for a small robot or device that can walk through (new) 8" PVC pipe and verify that the pipe is round. That is, pipe that has already been buried. The device would start at one manhole, and walk to the next manhole, recording the slope, distance and, as mentioned, circular-ness of the pipe.
Max range required is 120 metres. D
oes not necessarily require video, but some sort of info recording that can be read once it appears at its destination manhole.
