I have been playing around with my Arducopter for a month or two now and it has been performing well. However, since last week it has started yawing like crazy. It tilts while taking off and then starts spinning rapidly in the air. I have fli
I have a MB1200 sonar from the DIYDrones store. While working with it recently I observed some very weird behavior. I was getting pretty bad altitude hold in Loiter and AUTO modes. When I would analyse the sonar_alt logs, it would have a few tr
I have a very basic question regarding AUTO mode. If the quad is in the middle of navigating to WPs in AUTO mode, and I switch out for a minute or two to some other mode (say STABILIZE). When I will switch it back to AUTO, would it continue fro
I need a little help in identifying if my sonar sensor is working correctly. I recently purchased the MB1200 from the DIYDrones store and flew with it. However I did not get good Alt Hold in Loiter or Altitude Hold mode. I must confess it
I am a graduate student at CMU and out team is working on creating efficient navigation algorithms using point clouds. Unfortunately we are more inclined to software and controllers and have small electronics experience. Therefore I a
After some basic testing and flying out doors manually and with Alt_Hold, I put my arducopter in Loiter mode. I ensured I had proper GPS lock before hand. A couple of seconds of loitering later, the copter just shot up really high. It didnt
I just noticed a weird thing happening on my arducopter. I was doing some tethered testing and the quadrotor seemed to work fine. Then suddenly I could see motor 4 stall and therefore the quadrotor flip. I thought it might be the calibrati
I got everything calibrated according to the steps in the manual. Got the motors spinning during my ESC calibration. I set Ch5 of my radio on to stabilize mode. GPS is currently disconnected.
I am working on a project to enhance outdoor SLAM techniques with my Arducopter. In order to do that I need to mount a Hokuyo Lidar on the UAV. Payload wise I dont think there should be any problems since the laser weighs aroun
