Homebuilt ROVs Forum

Hi All, It has taken about a month to get the baseline ArduSub software working with the BBBMINI. Much of the time was spent debugging the various updates to the software and coping with several changes to the ROV Thruster configuration layout. Since this ROV is a six Thruster Vectored configuration...

Hi All, Linus Penzlien and I have been working with Rusty at Blue Robotics to properly configure the ArduSub firmware to appropriately drive the horizontal and vertical Thrusters in my six thruster configuration depending on the desired ROV motion input from the GCS (QGC) gamepad joystick inputs. Va...

@KR2_Diving, Blue Robotics has told me that they have had no vacuum leakage over a 24 hour period after pumping down with an oil vane vacuum pump which is much better than my diaphragm pump. Using my diaphragm vacuum pump I was able to evacuate either of my two WTCs down to between 560 - 580 mm Hg. ...

@Jaman42,
I used 10-24 stainless steel flat head screws, instead of the more common 10-32 screws, to hold the chassis 1/2 inch thick HDPE sides to the chassis center section. The 10-24 screws make a very solid connection.

Hi All, After having second thoughts about powering the Power Control Board wit a live LiPo battery, I remembered that I have an AC powered 12 amp peak 13.8 vdc battery eliminator, complete with overcurrent and short circuit protection, that I can use to check out the integrity of the Thruster Power...

Hi All, Believe it or not I was able to literally cram the battery tray, complete with the Power Junction Board connected to the Thruster cable penetrator power cables, into the Battery Compartment WTC without breaking or appearing to short any wires in the cables. Also, the bullet connectors appear...

Hi All, It turns out that we had the wrong thruster configuration version of ArduSub loaded on the BBBMINI. Once we corrected that issue, joystick input to QGC from the Xbox 360 game pad appears to be driving the BBBMINI thruster pwm outputs correctly for forward/reverse, yaw, and vertical assent/de...

Hi All, My friend, Linus Penzlien, and I have been busy porting the ArduSub firmware over to the BBBMINI and have been achieving a few successes so far. We are presently using the latest version of Debian (2016-02-16) recommend by Mirko on the BBBMINI, QGC version 2.9.4 for the Topside Control, and ...

@crazyrobin,
How do you plan to seal the dc motors against water intrusion?

Hi All, I have attached the ROV end cable penetrator to the neutral buoyancy Tether as shown in the picture below. Since the Tether is 75 meters long I stripped approximately one foot of insulation off of the ROV end of the tether to give me a sufficient length of twisted pairs for connections withi...
