ROV Speed
when designing an ROV from scratch, a balance of motor power, propeller design, and the size and shape of you craft all affect the final speed your ROV can achieve. My question is what is a normal speed for an ROV designed to survey small areas like what most people build? I was guessing that it mus...

Jets With Valve Control
Has anyone investigated using water jets in an ROV instead of a multi-thruster system? I am imagining a single flow source like a pump with a diffuser inlet attached to a multi-outlet valve manifold. The manifold would use one actuator with position control (like a servo) and would duct the flow to ...

Re: Google Sketchup is being a pain
Evan1 Is exactly correct. "Intersect Faces" becomes your favorite function if you are used to parametric modeling, and I also scale everything but only to 100X. Another note is that you can increase the resolution of circles by clicking the center hole spot, and then typing a number and th...

VR control
Is anybody on the forum using VR goggles like Google Cardboard or something or the like to control their ROV? I am toying with converting a pair of lab goggles with some lenses from ebay, a small screen, and a 3D-printed support structure. Thoughts?

Re: modular ROV concept
Hello fellas, life has gotten in the way of my ROV project for the last year but recently I've been able to put some work in. I am still pursuing the modular cube design. I like it because it allows me to adjust my design based on what I need at the time. In my current place I can't afford to finish...

Re: modular ROV concept
Here is my latest update after a lot of development: I have almost all of the cubes done; I ended up going wit 3/8" polycarbonate sheet which I CNC cut and chemically welded together for waterproof-ness and strength. Then I used 1/16" silicone sheet with a 40A durometer rating as a gasket ...

Re: controlling ESCs with a joystick
that's it?!? awesome, I will try when I get home...what about making the ESC go in reverse? I've seen that some ESC's will go in reverse from 0-90 degrees and forward from 90-180 deg. when sent commands from arduino, is that true?

Re: controlling ESC with keyboard commands
Thank you for your help KR2_diving. I ended up deciding that a simple joystick would be easier to work with. I have another post on that as well, if you are able to help with that it would be much appreciated!

controlling ESCs with a joystick
If I have this code which controls two servos with a joystick how do I make it so that instead of controlling a servo motor, it controls a Forward/reverse ESC? I need it to control 4 ESCs. (motor one and two ccw when joypushed foreward, cw when back, and motor three and four are ccw when joy is push...

controlling ESC with keyboard commands
Hello everyone, I am brand spanking new to arduino so i'm looking for someone to help me on my "modular ROV". Basically what I need is this: I have five brushless motors with five ESC's I would like to be able to press a key to activate one or two motors at time in either clockwise or ccw ...
