Re: [PSUBS-MAILIST] ROV
my project is desiigned for harbour use so i dont really need more than 10m
/ 30' depth.
the tube i have is underground sewer pipe, 20" long and 5mm thickness.
i'm actually using the videoray as my inspiration. my thrusters are
external, and are mounted in oil filled pods (or will be when i get the
oil). they are dc motors with a 5:1 planetary gearhead. they dont pull too
much current even under load and i am using r/c aircraft props. these i
have found also dont give too much drag but give a lot of thrust.
what are you usiing for control? i currently have a velleman kit for
control. 10 i/o, 50m range over 2 wires, current loop based i think. i've
built it into a case. 2 joysticks and several other lever and switches and a
5 1/2" monitor.
i also have a basic stamp which i intend to use for depth and heading info
but might use that for control instead
