Moki ROV (Another DUTCH ROV)

Post by Moki »

Just be sure to read the full topic, as lots of progress has been made after the start of this project.Also check this thread: viewtopic.php?f=41&t=1520

Just 2 weeks ago, I got into the ROV World.
See what it got me so far ;)

ROV:
Not my own design, just my own handywork with the Sealion-2 as example.

BOM:
2 Raspberry PI's (one inside the ROV, one as a controller station)
1 Xbox360 controller (connected to the ROV controller)
1 Bitwizard I2C servo board (7 servo's can be fitted)
2 Logitech C510 webcam's (one converted to IR)
2 x 35w/12v LED spots
10 x IR LED (Led ring at backside, around IR Camera)
4 x Rule 1100 bilge pumps with Dual Way 320A Brushed ESC Speed Controller for 1/8 & 1/10 R/C Car / Boat from dx.
4 small servo's for Webcam movement
1 (old) ESC for light control
1 Openrov DEPTH/IMU sensor
1 IPhone lens set (1xFisheye on Front, 1xWide on backside)

Software:
Own build Client/Server UDP based ROV software
Client-side (Xbox controller, using jstest + UDP support)
python ms5803-read.py /dev/i2c-1 0x76 (for Depth Sensor, added UDP support)
RTIMULibDrive (for IMU, added UDP support)
Mjpg_streamer (for live video streams from webcams)

I am sure, having skills like "RC Builder" and "Linux Hacker", helps to keep the build time this short.

Basically it was just buying the parts and putting it all together ;)

Nothing is really fancy or new stuff, most of it came from google or this great forum!

Hi !!

Let me ask you a question

The aluminum tubes were enough weight for buoyancy?

No, but buoyancy can be adjusted by filling the tubes (I used 1.3Kg) with "Soft RVS" (Stainless Steal Pellets/shot, try your local diving shop)

ha ha. That's what my 'development station' looks like. Except mine isn't quite so organized. :)

I guess, ROV building is "on-hold", until spare parts are found. I guess, a 2A step-down isn't enough to power 4 x 5A Rule 1100 Bilgepumps. Found a nice 20A 24v->12v replacement part on Ebay.

Who was it, that said: Electronics run on smoke, once the smoke leaves the device, its broken.
