We at COAST have just built out ROV and are testing it. We have noticed that the acrylic enclosures seem to have stress patterns and small cracks around the edges. Small cracks in acrylic, can quickly become big cracks, and it concerns us. So, are there any alternatives available such as a polycarbonate that aren’t quite so brittle?
We have sen the same thing.
Do you mean cracks in the acrylic dome, or you are using an acrylic tube?
If tube toss that and go with an aluminum tube. I never needed to see all my electronics through a clear tube, i feel better knowing the aluminum tube won’t crush (my 8" tube is 3/8" wall, 9.525mm thick).
