Hello fellow OpenROV users
here i will post a build-log of sorts !
i had initially been looking at the excellent designs by Mr Russell Coffield and team at Interspec http://interspec.org/ but felt ‘out of my depth’ with the software side of things. Thats when i spotted a part-assembled OpenROV on a well known auction site, that came with loads of invaluable accessories gathered by the previous owner including T100 thrusters and machined aluminium endcaps.
So OpenROV #439 is a version 2.5B for which i intend to utilise the standard OpenROV electronics platform with the intention to carry out the following modifications, many of which are inspired by the interspec designs :-
- A custom built chassis from router cut HDPE or similar, with float pontoons from router cut polyurethane foam.
- Thrusters shall be Blue Robotics T100 , using the standard 18A ESC’s as supplied with OpenROV
- On board Li-Po battery packs. ( 2x 11.1V 3S Lipo, 4500mAh )
- A proprietary neutral buoyancy tether if i can obtain something suitable for reasonable cost.
So the last month or two has been spent in what little spare time i have, reading and trying to understand the OpenROV system ( software notwithstanding - i will leave that to the experts ) , planning my attack on the build, purchasing some components and taking steps backwards due to a blown ESC and resulting fried Beaglebone - which i am pleased to report is now completely resolved.
i now have electronics all working, and thrusters functioning from joypad control- seemingly correctly albeit in a bucket of water.
Next Stages are:-
Name the project.
Tidy up wiring in main electronics assembly - in particular shorten the camera USB lead.
Make seperate wiring junction box
Make battery housing(s)
Design & make chassis
i will post sporadic updates as and when i make any progress!
