SeaMouse ROV Construction Gallery

These are photos of my first ROV, the SeaMouse, which is based on an original ROV design by Harry Bohm and Vickie Jensen.

Fore View Thumbnail

Bow View
The frame is constructed, as per the Bohm & Jensen instructions, of PVC pipe I bought at a local hardware store. I made slight modifications to accomodate the floats I used. They are attached with hose clamps which are fed through slots I Dremeled in the frame.

Aft View Thumbnail

Aft View
Here is an aft view of the frame; I have inserted dummy thrusters into the mounting brackets, to show how they will finally be mounted.

Bottom View Thumbnail

Bottom View
I've flipped the ROV over so you can see the bottom of the frame here. In all the frame photos, note the holes drilled through the PVC; this prevents air from becoming trapped in the frame and making the ROV buoyant.

Power Supply Thumbnail

Power Supply
I didn't dive in and purchase a battery and charger and all that right away. Instead, I acquired this 12V rechargeable supply which is meant to be used by campers and such. The ROV power cord is a female lighter socket, and I have a patch cord with two male ends that goes from the port on the power supply to the ROV power cord.

Control Box Thumbnail

Control Box
Here is the control box for SeaMouse, yet to be labeled. The left switch controls the port thruster (FWD and REV), and the right switch the starboard thruster (FWD and REV). The SeaMouse has slight positive buoyancy, so there is also a vertical thruster to control descent and speed ascent, located above the right hand switch. The three cables at the top of the image go to each of the three thrusters, and the lower cable goes to the power supply.

Control Box Innards
Don't tell my theorist friends, but I did all the wiring and soldering for the SeaMouse controls myself, and they work! This shows the innards of the box when the job was done. Many thanks to Michelle for teaching me some very helpful soldering secrets that made this a lot easier.

Thruster Axle Thumbnail

Thruster - Axle
This is the axle of the thruster, where the prop will be attached. The final construction step will be to put this assembly in a film canister and fill it with wax to seal it against water. As you can see in this image, the holes in the motor were covered in hot glue, to prevent the wax from getting into the moving parts of the thruster.

         Terminal Thumbnail

Thruster Terminals
Here is the back end of the thruster, where the power wires have been soldered to the terminals. The holes and terminals have been covered over in hot glue. Additionally, the entire thruster has been wrapped in black electrical tape to prevent wax from getting into the motor.
