Submarine control - Steering servo motors and Motor contollers

zoomkat:
I assume you already have an arduino, multimeter, breadboard, jumpers, power supplies, etc. to support your project. That being said, I suggest you get a couple of the below servos and modify for continuous rotation (very easy), and the below joysticks, and start experimenting to verify your joystick control concept. I doubt anyone in the forum has built what you plan, so reading DIY ROV sites will probably provide info that you need.

Hi Guys,
Thanks for the help.
at this stage the application isnt really an issue (submarine, steering of a car, aerlons on a plane, the movement of the existing servo through the 180 degree rotation controlled by a thumb joystick is the convern.
I figure from what I have been told i use an Arduino Uno with two single axis joysticks (similar to the remote control game board that arduino do). WHat I need to know is, other than this, what do I need-

  1. power supply? what do you use - I will just have 3 large deep cycle batteries, but what do you guys use or reccomend.
  2. what other support boards/hardware do I need.
  3. where do I get single axis thrumb joysticks like the one on the hand held game remote?

Regards.
Mike

  1. Sounds good to me. Lead-acid have a low power density, but that may be adequate for you needs. You need to determine your motor amp draw and use the amp-hour capacity of your proposed battery to see if it meets your requirements. Moving up, you can go to NiCd/NiMH, and if that's still not enough, there's Li-ion and LiPo.

  2. Hard to answer, don't know everything you want to do?

  3. single axis joystick - Google Search turns up lots of hits?

where do I get single axis thrumb joysticks like the one on the hand held game remote?

I'd just get some joystick pots like below and just use the axis desired as you don't have to use both.
