I have several question, i'm using the erlecopter.
1- The description (URDF) of the erlecopter does not include the sensors, where is that done? i mean in which place, we associate a sensor to a particular part of the robot for exemple to a link. i do not found the file where is written camera bottom is associated to this part of the robot.
2- I also don't find the actual source code of the sensor, for a example of the laser or the sonar, i want to read how it is programmed so i can understand deeper if it is ideal sensors, or if some noise is added to the simulation..
3- i also want to know if a wind simulation is possible, and if yes where it is programmed and how we can use it ?
4- Can we vizualise the sensors with for exemple RVIZ ?
Thanks a lot
