Hello guys, I am doing a project which wants to control the helicopter by laptop so that the helicopter can follow the path we want. I got the 9DOF IMU from sparkfun and I can get the pitch, yaw,…Continue

thanks a lot for your reply,
I had understood that with a accelerometer and gyroscope, with mathematical calculations (integrals, derivatives, ..), one could know the position of an object in space .. The resulting position would not be…"
Luke Olson replied to xywang's discussion How to get xyz position from 9DOF IMU output?"The SparkFun IMU won't be able to provide specific location coordinates. It only provides information about the orientation and changes in movement. You could in theory use dead reckoning to determine position but with only one reference point…"

have you got any reply or solution for you problem?
I'm interested in the same thing, how to know the position of an objecte in the space from accelerometer and gyroscope through values from GY-85 6DOF 9DOF IMU for Arduino..
thanks a…"

Hello guys, I am doing a project which wants to control the helicopter by laptop so that the helicopter can follow the path we want. I got the 9DOF IMU from sparkfun and I can get the pitch, yaw, roll value from the IMU. I want to know how to convert these values to vector position, like in xyz axis. Thank you very much for your help. WangSee More
