Vertical motor not behaving properly


I'm done mounting my ROV. I'm controling the features from the web browser but under the "Diagnostic" menu, the vertical motor doesn't work properly. To begin with, the vertical motor starts all of a sudden, without having to turn it on. Then, to turn it off, I have to click "-1". And then to turn it on again, I have to click "0". Regularly, it turns on by itself. Weird... Any idea ?

Thank you,


Update (12/06/2016)

Here's more information: I reinstalled the firmware on the beaglebone board, as well as on the Arduino board. Now it seems the vertical fan doesn't start by itself, however the icon issue is still there. When I click -1 or 0, it starts spinning CCW (both of these icons). To stop it, I need to press 1.

Also, if I press Ctrl, and release it, the motor spins. To stop it, I need to keep Ctrl pressed.

So! I got my OpenROV fixed. If you have a motor behaving funnily, you might want to try the following procedure. Credit goes to Nima from OpenROV who was of great help with this!

First off, update the software and the Arduino firmware, as explained in the OpenROV documentation (I don't expect this will fix this type of issue, but it's worth updating anyway).

You can re-calibrate your ESC firmware. this is something that doesn't get done very often, but sometimes the ESC's driving the motors need their firmware updated.

The ESC's (electronic speed controllers) don't share the same firmware as the Arduino on the Controller board. In order to flash your ESC's manually, follow these instructions:

Download PuTTY. It is a program that allows you to manually connect to an IP address via a terminal window. When you run the program, connect to the IP address:

If there is no connectivity issues due to hardware, or your computers static IP address, it should open a terminal window.

Type in the following lines of code:

cd /opt/openrov/cockpit/linux

sudo bash

It will then run through the process and end without error.
