Robobot 4

Back to Robobot

Start the robot

At the competition, the robot must be started using the start button.

Press the start button (be prepared that the wheels will turn after a few seconds (to load the Python app)).

Start from the command line

With a SSH connection to the robot, navigate to the directory with the Python app:

cd svn/robobot/mqtt_python

Change the IP address in the script mqtt-client.py to match your robot (in the bottom of the file, localhost should do). Then execute the script by:

python3 mqtt-client.py

This should do the same as pressing the start button.

The app can take parameters:

python3 mqtt-client.py --help
 -h, --help            show this help message and exit
 -w, --white           Calibrate white tape level
 -i, --hostIP HOSTIP   Set host IP, default is localhost
 -g, --gyro            Calibrate gyro
 -l, --level           Calibrate horizontal (not implemented, but maybe an idea)
 -s, --silent          Print less to console
 -n, --now             Start drive now (do not wait for the start button)
 -m, --meter           Drive 1 m and stop
 -p, --pi              Turn 180 degrees (Pi) and stop
 -e, --edge            Find line and follow the left edge
 -u, --usestate USESTATE
                       set mission state to this value
