Is there a way to control stepper motors want to use them as a base for a robot differential drive

running pi 3 with version 1851

i can use runtime arduino.serial with both the uno and the mega and run the runtime servo to move various parts.

when I run a simple python script the uno works correctly but the mega moves the servos to extreem positions (head and left arm) and i have to power down.  I posted my script, under harland, name small test pi.py

Hi

I'm looking for some guidance

I'm running MRL on a Raspberry Pi

I'm looking to see if it is possible to stop Chromium from loading when MRL starts up

How can this be done?

Hi,

Hello,

If i've right , this line :

Hi All, I have now managed to get the Arduino to talk to MRL properly, I can run the minimal script and the audo works fine, the Arduino flashes away but the servo refuses to moves. I have the control pin on PIN 3 of the Arduino as suggested in the script, the Sliders do not operate the server either. Tried several servos, what do you think I am missing here folks - Thanks

some  rss feed script for myrobotlab? I found this script https://github.com/MyRobotLab/pyrobotlab/blob/master/home/steveh110/parser.py but I do not know what library is added
