Hi guys,i've been putting up an arductopter kit with magnetometer GPS and all loaded with an NG firmware.When i start the engines the back engine start way after the others and when I have my throttle at min and I incline it backwards the prop does n
In the arducopter NG code, there is a line for disabling or enabling the xbee serial communications. If it is enabled, the xbee works perfect for use with the configurator, but the usb cable won't work if that line in the code is enabled. If I disabl
I have managed to get my APM up and running using two XBee 2.4Ghz modules without any problems, however if I swap these modules over and replace them with the XBee Pro 900Mhz modules I get no data coming over the link. I have set my baud rate
It looks like the NASA guys came along Some issues with dealing with radiation But I see there is a radiation detection meterBy sparkfun should I be concerned with installingOne for my quad for taking high altitude flightTesting
I'm an undergrad mechanical engineering student at UCSD and I've started putting a few projects together that would require a decent amount of knowledge about autonomous controlled vehicles. I do have some experience with creating aut
Everything works fine until I get to the compass offsets. It displays scrolling data but everything is zero and never changes as I move the quad. I did run the CLI "a" command and made sure that the mag was activated.
during my first full test flight today i'd noticed a couple of glitches, on arming the motors sometimes the rear or right wasn't spinning up. disarming and re-arming seemed to fix it. So carried on and got the quad up in the air and had a f
I'm playing with gyroscopes (ITG-3200) and looking for adequate filters.
The problem is, it seems everyone want at least 6DOF, 9DOF, 89DOF ... I just need 3DOF and only have a 3 axis gyroscope. I cannot find information on an adequate filter for
I am working in a university lab, for a PhD student, and we are currently using APM for charactering an non-standard airframe. The airframe we are working on experiences quite a considerable amount of Dutch Roll when exiting a bank.
