"Is there any chance you could explain how you implemented the four sensors into the code, I am trying to incorporate it with using the mission planner 1.2.36.  We are trying to use sonar sensors as obstacle avoidance, in an actual flying…"

"thats fantastic Chris... did you use another arduino board along with the ardupilot mega for intigrating the sensors?"

"I am currently working on this. First implementation for 4 sensors(front,back,right,left) is done, hardware is set up. I am right now looking for a safe way of testing this (At the moment I am trying to get a simulation working), because I am afraid…"

"I would love to get this working. That said, I would really love to get it working using video. Maybe OpenCV? But, I am sure Sonar would work just fine, I'm just personally interested in computer vision and analyzing live video on the fly."

"Ok...thanks for that...do you also want to implement obstacle avoidance? How may sensors do you intend to use?"

"I have a sonar for the arducopter and will be installing it soon. I'm waiting on a new motor and esc. Maybe then I can be of some help."

"I have already bought 6 Maxbotix (XL-Maxsonars EZ/AE) range finders. I am trying to integrate them in the Arducopter code but i do not understand which part of the code to modify to add these sensors in a daisy chaining format for obstacle…"

"Thank you very much for your quick reply!!  My main objective is to add sonars and show some results to my Professor at the uni. he wants to see the problems and then find an appropriate solution Could you please guide me on how to proceed with…"

"Hi I am trying to add MaxBotix ultrasonic sensors for obstacle avoidance as well. Did you come up with any results?? "
