Basebot data
Basebot data needs to be saved into a file to make it usable for MATLAB.
A log is available after a basebot run. E.g. by typing start in the monitor area or by pressing the start' button on the robot itself.
The logfile will be sent when the mission is complete, or alternatively by sending the command log to the robot.
Arduino IDE
I couldn't find a way to save the serial monitor data to a disk file.
So find another app that allows communication in the serial line and save the output to a disk file (or allow copy-paste to do the same).
Visual Studio Code
In the monitor area the log data is shown (e.g. after typing log), like:
The data received in the monitor area will be saved to a logs directory on the basebot directory.
The saved file could look like this:
--- Terminal on /dev/ttyACM1 | 9600 8-N-1 --- Available filters and text transformations: colorize, debug, default, direct, hexlify, log2file, no control, printable, send_on_enter, time --- More details at https://bit.ly/pio-monitor-filters --- Quit: Ctrl+C | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H 0.67 2.00 0.26 -0.26 0 0 0 0 1 0 0 0 1 0 2.13 2.43 1.17 2.00 0.26 -0.26 0 0 0 0 1 0 0 0 1 0 2.13 2.43 1.67 2.00 0.26 -0.26 0 0 0 0 1 0 0 0 1 0 2.13 2.43 2.17 2.00 0.26 -0.26 0 0 0 0 1 0 0 0 1 0 2.13 2.43 2.67 2.00 0.26 -0.26 0 0 0 0 1 0 0 0 1 0 2.13 2.43 ... 1998.67 0.00 -0.36 -0.34 0 0 0 0 1 0 0 0 1 0 2.85 3.23 1999.17 0.00 -0.36 -0.34 0 0 0 0 1 0 0 0 1 0 2.85 3.23 1999.67 0.00 -0.36 -0.34 0 0 0 0 1 0 0 0 1 0 2.85 3.23 2000.17 0.00 -0.36 -0.34 0 0 0 0 1 0 0 0 1 0 2.85 3.23 2000.67 0.00 -0.36 -0.34 0 0 0 0 1 0 0 0 1 0 2.85 3.23 2001.17 0.00 -0.36 -0.34 0 0 0 0 1 0 0 0 1 0 2.85 3.23 % Set Sample time 500 usec. Measured Sample time 499.99 usec.
The numeric content depends on the code (the first column is here time in ms). The lead-in text must be removed before loading into Matlab.
Linux
In Linux, the serial device is called /dev/ttyACM0 (typically), and to copy the robot output to a file is:
$ cat /dev/ttyACM0 > aaa.txt
And use ctrl-C to stop.
You can, in another terminal, send commands to the robot, i.e.:
$ echo "start" > /dev/ttyACM0
This is the same as pressing the start button.
Apple
I don't know
