Trial No 2 - The Swimming Pool

Le Tue 13 October 2015

The second test for the ROV was in a pool. This allowed a little more room to maneouver and also a little more depth. I am very pleased to say the ROV performed beautifully. Here is the description of the trial, a video and a few shots.

Bath-time for the ROV

Le Fri 18 September 2015

This was an exercise is seeing how quickly I could flood the bathroom. I found that I was quite successful at this and had the floor awash within seconds of putting the ROV into the bath for a quick trial. The trial was successful.

ROV Motor Upgrade

Le Mon 03 August 2015

The ROV uses the same motors as the OpenROV, namely 2213N 800Kv brushless DC model aircraft motors. Because model aircraft tend not to be used underwater, the motors are not really designed for marine use. The OpenROV community came up with a solution to this problem and explain it very well in their online guide. The solution was to swap out the standard bearings for ceramic and stainless steel hybrid bearings and treat the windings with corrosion proofing paint. This page describes the same process, more or less.

ROV Thrusters

Le Mon 16 June 2014

There are several possible avenues that can be followed for the Thrusters on the ROV. The simplest is to do the same as on the OpenROV project where brushless outrunner motors are exposed to the water. Other projects have made use of small 12V DC bilge pumps (ideally brushless). Another option is to adapt the Open Source Thruster Project idea and encapsulate the brushless DC Outrunners in a container that is filled with oil. A final option is a magnetic coupling between the coils within some sealed motor pods and the magnets embedded in a propeller arrangement.
