It seems as though there have been a few people asking about how they can access the raw sensor information being generated by the IMU's on the Ardupilot boards. Is there a good reason as to why that hasn't been addressed or am I just missing somethi
Read more…We have been running into an issue quite often when flying at certain altitudes and 'near' structures. We are doing autonomous waypoint navigation and all of a sudden the GPS position jumps anywhere from several feet up to a few hundred feet. Obvious
Read more…I am sure that some of you have experienced the same issue that we have. We are flying a rather heavy hexacopter configuration which pulls a substantial amount of current just to hover. Due to the proximity of the power distribution board and the mag
Read more…We attempted a little parametric study to optimize our UAV's flight time using the motors, propellers, and # of batteries as our controllable variables. First we optimized the rotor/motor combinations which is described in another thread. Then we dec
Read more…I haven't seen much success with this so I will throw this out there again and see if it goes anywhere. I am building a UAV to fly a search grid and autonomously detect people using various image recognition algorithms. I need to be able to extract G
Read more…I thought this was neat and worth sharing. We were wanting to see how effective it was to rearrange our ESC's on the quad in attempt to keep them cool. The first five shots are of the quad kits sold on DIY drones. The last two images are of the Walke
Read more…A few of us are wanting to make our own ducted fans out of either carbon fiber or kevlar. We want to make them modular and easily installable on the currently manucatured quad or hex frames sold by DIYDrones. This is a very preliminary shot at it. Th
