Software class - and example
This page also has an explained behaviour plan example (bplan20).

Low-level robot control
Robobot level 1 with interface to hardware and pose generation.
Line sensor
Description of the Line sensor functionality.
Robot.ini configuration file
[pose] gear = 19.0 wheeldiameter = 0.146 enctickperrev = 64 wheelbase = 0.243 log = true print = false
See Raubase configuration file for explanation.
Make a new behaviour plan
The easy way to make a new behaviour plan module is to copy an existing plan and rename a number of elements.
See Robobot_new_behaviour_plan.
Sensor calibration
See sensor calibration, which covers odometry, distance sensor, and gyro.
Calibration of the line sensor is found here.
Camera calibration is needed, as the lens distorts the image quite a bit.
Video streamer
A video streamer called 'motion' is installed.
The motion config file need a few changes:
sudo nano /etc/motion/motion.conf
Set in the 'System control' group
- log_file /home/local/.motion/motion.log
- target_dir /home/local/Videos/motion
- video_device /home/local/video0
In the 'Live stream' group
- stream_localhost off
run motion
To run the streamer, SSH to the robot and start motion
$ motion [0:motion] [NTC] [ALL] conf_load: Processing thread 0 - config file /etc/motion/motion.conf [0:motion] [NTC] [ALL] motion_startup: Logging to file (/home/local/.motion/motion.log)
NB! Remember to stop the streamer before trying to use the camera for other purposes.
Stop by ctrl-C
View the stream
To view the result, use a browser to open the address of the robot and port 8081, e.g. if the robot has IP '192.168.1.151':
192.168.2.151:8081
You should now see a stream of default 640x480 at 10 FPS as default; more options are available in /etc/motion/motion.conf.
The stream has a significant delay, and the framerate may be lower if the network is slow.
