Discussions and queries about ThunderBorg and MonsterBorg.

Hello,
I have a two-ThunderBorg robot up and running and I occasionally get these error messages:
Failed reading the drive fault state for motor #1!
Failed reading the drive fault state for motor #2!
Failed sending motor 1 drive level!
Failed sending motor 2 drive level!
They seem to occur after some spirited starts-and-stops as you might find when you are testing a new robot.
The LEDs turn green-then-blue and the robot halts. After a moment, the robot resumes operation.
Any thoughts on where I can look to find the root cause?

Hi, I've got a robot whose Raspberry Pi is currently powered entirely from the six pin cable from the ThunderBorg. I'm using a 12V Makita power tool battery connected to the ThunderBorg's +/- terminals. All works fine, except that as the robot has grown more complicated, the power load has grown and I'm now having brownouts.

I have used the codebase so far with 2.7.12 on Ubuntu Xenial with no problems,
Can I safely assume that it will work for all higher versions of python2?

I am currently building a remotecontrolled rover (UGV) for a project in school. I've decided to base it on the thunderborg platform and it's code examples. What I want to do is to make my thunderborg controllable through a web client, like the monsterWeb program, but only using sliders. I've managed to make two sliders to control the speed of each side of the borg, but still need to start it by using buttons, and every time I change the speed I have to restart the Drive function, for the speed to change.

Hi, I want to be able to access the other GPIO pins for other projects on my ThunderBorg, does piborg sell any device which is intended to breakout these pins with the Motor Controller attached? At the moment the motor controller only uses 6 pins but its placement restricts access to the remaining pins.
If there isn't anything available off the shelf, whats the best way to access these? Is there any specific cable/board I can buy or make?

Hi,
I across the note below from https://www.piborg.org/robots-1/monsterborg:
"Raspberry Pi 4 - Model B compatibility:
We have tested MonsterBorg with the Pi 4 and it works fine, however the 5V supply does not fully meet the Pi 4's 2.5A specification."
I was wondering if there is a way around this, any thought would be much appreciated.
Cheers.

...in the Store to order. Where can I get them from?
Cheers

Dear,
We have a question about the Monsterborg track in "monster-self-drive" mode.
The code for course recognition is made for colored tracks (red, blue, green) but is not made to drive the monsterborg on a black track.
We made several attempts to modify the code in the file "monster-self-drive/Settings.py" by changing values of MinHuntColor and MaxHuntColor so that the camera can recognize the black color of the course, but we did not succeed.
Can you show us how to adapt the code to make monsterborg self-drive
on a black course?
Thanks.

Hi,
I'm tried to write a code simple program to make the monsterBorg robot move continuously and stop if it detects any obstacle using the Sharp distance sensor.
The program is very simple, tbh I just used a few lines from monsterSequence code and combined it with the distance sensor code.
I have attached the screenshot of the error that I'm getting.
Please help me, I'm not sure what to do for this type of error.
