This ROV is controlled by a Basic Stamp2 and is fully controlled via StampPlot. This allows for a GUI interface and feedback from the sensors while you are exploring the vast depths of the local lakes.
Initially I had hoped to have an un-tethered ROV. I tried to transmit data using Bluetooth from a laptop to the ROV underwater but as soon as it went under the surface all communication stopped. I also tried data communication using two radio transceivers operating at 438Mhz but got the same result.

You can’t use HF signals in water unless they are very low in frequency. Submarines use signals in the 15kHz range. Hard to do.
Otherwise, you can use sound: ultrasound transducers should work well.
Nice project! I really liked the videos. I also like the way you used StampPlot for the surface side interface. I will have to try something similar with mine.
One question — what did you use for speed control on the thrusters?
zdeubeu true, i saw a presentation on low cost Acoustic Modem technology based on DIY work with fish finders.
http://wuwnet.engr.uconn.edu/papers/p071-benson.pdf is the paper.
How’d you waterproof the motors?
The one model has submersable sump pumps that are waterproof, the other looks like the motors are geting full contact with water, which is so-so iffy workable in fresh water, useless in salt water. I am working on one that has long motorshaft motors in a PVC housing that goes through a few snug & teflon lubricated o-rings. The other end of the PVC housings has a watertight large o-ring threadded cap. Rubber compression fittings for insulated wire allow control cable inside watertight.
Even expensive learning center aquarium ROVs have no speed controllers, just full thrust fwd/rev. You learn to feather the controls with a good pilot’s touch. It’s nice that you can find 12V color & sound cameras for under $100 lately, JUST over $100 with a 5″ monitor.
Cool project! I’ve been working on something similar, though I’ve run into a wall. Can you provide any information about the GUI control? I plan on using the Arduino (multiple actually) to control my submarine, but need a little help with the GUI.
have a look at my website, WeightmanRobotics.com for help / ideas on GUI and other info on the ROV at the top of this page.
So many good releases…
