In an effort to get my unit neutral in water I added a wood platform with holes every .5 inch screwed to the top where the name is. I made mine on a laser cutter but it could easily be made by hand. This was so I could easily attach things to the top. I tried the ping-pong balls with netting but they are hard to attach. I then added a small tire tube. Now I can adjust the air in the tube to make the unit neutral. I also down loaded free software called "FreeScreenVideoRecorder.exe" to capture video while I drove the unit around. The software works great! Google the name and you will find it. I drove the unit around tonight in my test tank and captured video for the first time. The video doesn't look like much because my test tank is white plastic.
My main problem to really use the unit in our pond is I need to be able to drive the thurster motors slower. The OpenROV really moves quickly and the battery voltage drops, knocking the unit off line. Can we get some firmware to limit the motor power? Even with the X'Box USB controller it is hard to go slow enough. I could make it 4 or 5 min. by being careful. The vertical thruster I can run at full power with no problem, but I still have the plastic impeller on it. I have the brass props on the other 2 motors.1836-floatplate.jpg (100 KB) 1837-openrovtsttank3.jpg (160 KB) 1838-openrovtsttank2.jpg (159 KB)
