Robobot MQTT-client

Back to Robobot_B

MQTT-client in Python

This skeleton is intended as the mission controller app.

mqtt-client.py

This is the primary file in the mission control skeleton.

It is intended to run on the Raspberry Pi, using the command:

cd ~/svn/robobot/mqtt_python
python3 mqtt-client.py

All the interfaces have a network interface except the GPIO (General Purpose Input Output). This allows the app to run anywhere with network access to the robot.

Command line parameters

The app has defined a few command line parameters, among these help:

python3 mqtt-client.py --help
% Starting
usage: mqtt-client.py [-h] [-w] [-g] [-l] [-s] [-n]
Robobot app 2024
options:
 -h, --help    show this help message and exit
 -w, --white   Calibrate white tape level
 -g, --gyro    Calibrate gyro
 -l, --level   Calibrate horizontal
 -s, --silent  Print less to console
 -n, --now     Start drive now (do not wait for start button)

The command line options include some sensor calibration. The distance sensor calibration is missing (but needed).
