There is this one comment in the code, which makes me believe that the PS3 driver somehow maps buttons to (virtual) axes as well: # Strange bug: left button as axis doesnt work. So use button instead I never used the PS3 controller myself and work with an XBox controller instead. Those have default ...

PySDL dependency seems to be added just a day ago: https://github.com/bitcraze/crazyflie-clients-python/commit/19542360d869827cdb81f595628573fd1545fe90. I didn't update yet so I am not sure about your second error. However, the first one looks like you might try to use Qt4 and Qt5 at the same time. ...

How many buttons does your joystick have according to jstest? For example I get the following Axes: 0: -3565 1: 2142 2:-32767 3: 2181 4: -1004 5:-32767 6: 0 7: 0 Buttons: 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off 8:off 9:off 10:off Hence, I have only 11 buttons and I would need to change the i...

Great progress! I guess you are just using a different controller than what Oliver used to use (PS3?!). If you look in joy_driver_pid.py, line 128 you can see that the offending button is defined as index 13. If your controller has less than 14 buttons, you would crash. You can use jstest to see the...

Do you mean a list of supported transmitters or where to buy them?
I think the only real supported product is the ESKY controller, however it requires a special firmware since the protocol is slightly different.
There were a few projects here on the forum of home-made transmitters as well.

This is definitely not normal. In fact, because it is written in python it should be technically impossible to segfault... You can try running it with gdb to get a full stack trace on where the crash is happening and post the stack here.

I guess that is an arbitrary choice. The leap motion SDK gives you back angles in degrees. The crazyflie itself takes numbers from -30 to 30 for roll/pitch, which somehow map to the angle (not sure how exactly - would need to look in the firmware code). The yaw is the angular rate between -200 and 2...

There was a master thesis on that: http://www.bitcraze.se/2012/06/camera-addon-master-thesis/ I think the achievable resolution with the Crazyradio alone is fairly low. Additionally, getting high-bandwidth also increases the latency, which is bad for sending the control commands or getting real-time...

Can you try adding a print statement in pygamereader.py, line 66 to print the axisvalue? Just to see if there is an issue with the overall range of the yaw axis.

Well done! Thanks chad!
