Hello!

as a newbie I feel very lost with the raysensor. I'm supposed to use is it as example for a laser sensor plug-in. So I tried to understand the sourcecode of the raysensor, but I really can't handle it..

Can anyone help me, describing the main functions of the sensor and explaining how the sensor is working? and furthermore maybe how I use it as plugin (which things I can change with parameters, as angels etc.)

thank you in advance!

Hi Boni,

You can have a look at the example here to figure out how to use the sensor.

Look at the code of raysensor... Here you can find all the message definitions: http://gazebosim.org/msgs/ You might be interested in this: http://gazebosim.org/msgs/3.0.0/laserscan_8proto.html

or if your looking for ros messages than you can look at: http://docs.ros.org/api/sensor_msgs/html/msg/LaserScan.html

If this answers didn't help, be a bit more specifc with the question.

Create a new question, if you want help with parameters.
