|This is the Tilt Camera Mount I made for the Seafox ROV. Construction was pretty simple, the frame is made from Plexiglas and uses a small Radio Shack motor and two small gears to turn a threaded rod which is connected to the back of the camera which is housed in a 1-1/4" PVC coupler. The Camera is free floating inside this coupler, It can't be seen in the picture but inside the coupler is a metal ring in which the camera slides in and out on.
The motor on this mount is Not waterproof, I run the motor exposed to the water. The motor is an inexpensive 380 type motor I found at radio shack. It has been used for years and its still working.
