Picar-x No longer Responding to Python Commands via the Pi 4

Hi, I’m new to using the Picar-x. I was able to set it up correctly, initially successfully executing the servo zeroing python script, and had a short bit of success running the calibration.py script. But now it seems the robot-hat is no longer responding to commands send to it. I’m using a 3.0A USB power supply to the Raspi and a standard h/w kit. I’m connecting via ssh to the Raspi without issue.

Your help is appreciated.


One of the wires from the battery pack came loose. I soldered it back into place and all good.
