Re: Kiwirov's ROV Build

Very impressive bit of work, Kiwirov. Yes, Canvas is a fantastic thing for GUIs. You make a good point re the inertia/constrained water, but depending on what the ROV usage is may not be a problem. Personally I have yet to find this out for myself, my "latest" ROV, (on the shelf now for ov...

Re: KR2 ROV

Congrats on the new workspace and progress KR2. My first thought was the regulator dropping a larger voltage when running off the battery, then I read further and you mention it getting hot. The quoted 20 volt max is assuming very little current load. What other things are you running off the 5 volt...

Re: New setup controlsystem

Hi tvc. You can write your control and monitoring as a webpage and serve it from the Arduino via an Ethernet shield. From what you describe you do not need the USB host. There are Javascript add-ons that allow you to use a game controller joystick in the webpage. I did similar but just used a standa...

Re: PS2 controller code question Brushless motor Arduino

Hi subn00b.

Maybe post this and the ROV servo/ESC code in the Control Systems and Tethers or the Arduino sections. Ready-made ROV control system!

Re: Trusters for my first ROV project

Hi crazyrobin.

I think pressure compensation is a good and simple way to waterproof BRUSHLESS motors. Just a suggestion for the motors you have, do some testing before making the housing, to check that the oil or fluid does not affect the brushes.

Re: PS2 controller code question Brushless motor Arduino

Just at a glance - I may have missed something. I'm guessing that you are using the analog input as a preset of some sort? The function stop() should be called parado(). Put something in that function, or it won't do anything. Distancia should be distance, as distancia has not been defined. The comp...

Re: PS2 controller code question Brushless motor Arduino

Welcome ljrc10. I'm surprised no-one has responded to your post yet. As to the PS2, I cannot help. You look to be off to a good start so why not just keep the joystick you are already using, and just add a second stick? Instead of sending the mapped stick variables direct to the servo function, you ...

Re: Please Explain Battery Output and Motor Torque

Likely because diving implies getting down to a specific depth, ie, where your subject of interest is. Once at depth, power usage should be minimal.

Re: Please Explain Battery Output and Motor Torque

Many variables. For starters, how big is the ROV? How fast? What is the intended environment? My approach would be to do some basic homework (refer "draw, thrust and components" thread on this forum) and take an educated guess at prop pitch and diameter and use that as a starting point. Bu...
