ROV Control Sketches – Fourth Edition

Le Mon 04 April 2016

This update is the eighth edition of the ROV control sketches. This update includes modifactions to the circuit boards and code to accommodate an i2C bus which the MS5803-14BA Depth Sensor and HMC5883L Digital Compass connect to.

Timelapse Camera Slide Version 2

Le Wed 16 March 2016

A while ago I posted an article describing a Camera slide constructed from the bits of a discontinued 3DPrinter project I was working on. It worked, but not very well. So I set about redesiging it with some other ex-3DPrinter bits and using a completely different approach. This new design uses a pulley around which a string or cord could be wrapped. This allows the CameraSlide traveller to winch itself along smoothly and easily. It is also less inclined to jam because the pulley is centrally located and allows the traveller to better follow the tracks.

ROV Control Sketches – Third Edition

Le Wed 26 August 2015

This update is actually the seventh edition of the ROV control sketches brought about by the hardware being mounted on the frame, with a proper tether and with the camera in place. These updated editions now have the motors turning in the correct direction to get the best out of the ESCs in the direction that most matters. It also implements proper triggering for the Horyzon v3 camera and introduces some work arounds to fix a mismatch between what the camera says it is doig and what the topside indicator LEDs are indicating. On this last point, the onscreen cues for the camera status are a better indication of what it is doing than the topside LEDs, so these will be eliminated from the sketch and circuit in a later edition.

Timelapse Camera Slide from a 3D Printer

Le Thu 02 July 2015

This is what happens to 3D Printer building projects that become too much of a drag. This timelapse camera slide was created using a whole heap of 3D printed bits that I had made for a 3D printer that I had designed. The camera rig controller is a RAMPS / Arduino Mega combination that would normally drive a Reprap style 3D printer. It is a relatively simple build and other than the 3D printed parts makes use of commonly available materials and components. The code provided can easily be modified for an Arduino UNO or Nano running a single stepper motor driver board such as an Easydriver or a Pololu board. there are some projects that just develop fast and easily - this was one of them.

ROV Control Sketches – Second Edition

Le Wed 18 February 2015

Well …. actually this is the fifth edition of the sketches seeing as they have evolved somewhat with the addition of better displays, more sensors, and more data being fed back to the topside station. So this page describes the two Arduino sketches and associated circuits have been developed to feed control commands between the operator using a PS2 controller handset and the ROV. The sketches and designs presented here are the basics required to run the ROV but have better developed data exchange between the two Arduinos. The circuits and sketches have been successfully tested on dry land with the 100m CAT5 cable tether in place.

ROV Control Sketches – First Edition

Le Wed 21 January 2015

Two Arduino sketches and associated circuits have been developed to feed control commands between the operator using a PS2 controller handset and the ROV. This brings together a number of the development sketches. The sketches and designs presented here are the basics required to run the ROV and have been successfully tested on dry land with the 100m CAT5 cable in place.

Control of the Horyzon HD Camera with an Arduino

Le Wed 21 January 2015

The ROV makes use of a HoryzonHD Full HD 1080p FPV camera V3 sold by FoxtechFPV for the pilot's view of the world and also to record or take photos. Because it is sealed in the ROV it is going to need to be controlled remotely via the ROV's Arduino. This page describes a test arrangement where the Arduino runs through a routine of taking photos and shooting movies using the HoryzonHD camera.

Sending Video through the Tether

Le Wed 17 September 2014

A method used for transmitting video through wired connections over longer distances is to use Baluns. This is the technology being used for sending the video feed from the ROV to any video monitor with a video in port.
