For the import error: You need to download and install pyqtgraph from here http://www.pyqtgraph.org/ (not available as part of most distributions as package). It is required for the Plot tab in the GUI to plot/export the sensor data. I am not sure about the PS3 controller. You should try to use diff...

This is a fairly ambitious project. The control scheme needs to run fairly fast in order to work, so you would need to run it on board on the crazyflie. On the other hand, if you finish that, you will learn a lot! I would recommend the following steps: 1. Make sure that you can compile and flash the...

2Mbps just means 2 Megabits per second, i.e. 2/8=0.25 MB/s = 250 kB/s. You can only achieve that if you buffer a lot (which increases latency again). For starters I would recommend going with the standard way of logging. There are two options: 1) You can write your own python script. There is a grea...

There is an interesting master thesis which contains bandwidth measurements here: http://liu.diva-portal.org/smash/record.jsf?pid=diva2%3A534744&rvn=1&dswid=8523 (click on fulltext on the top right to access the full thesis). 1) The minimum the crazyflie needs to fly is the control command p...

I believe Bitcraze used the Bus Blaster successfully (available from seeed studio as well).

What do you mean by putting the "crazyradio into receive mode"?

The lines between "[crazyradio]$ make" and "[crazyradio]$ " are essentially a list of what make executes. Hence, it creates the bin output folder for you (if it does not exist already).

I am not sure how to use the USB on the STM32 either. However, what is the issue with the communication speed over the crazyradio? Do you have an issue with the latency or with the bandwidth? It is possible to get around 3ms latency. Even if you get USB to work, I am not sure if it would solve your ...

What do you want to know exactly? The "export" command is only needed in order to enable make to work correctly (otherwise it wouldn't find the compiler). Make itself creates object files for every source file and later links all those object files together to get the resulting hex file.

If you change the Flight Mode from "Normal" to "Advanced" you can change the "Max thrust". The default is 80%. I believe this is just to avoid that the flie goes too high too fast. If you didn't put any additional payload on the flie, it should be able to lift off with ...

Cool! The API is documented in the wiki: http://wiki.bitcraze.se/projects:crazyflie:pc_utils:pylib Basically what you can do is setting roll, pitch, yaw, and thrust. If you want to do something more advanced (e.g. following waypoints) you will need external tracking (outdoors: GPS; indoors: Kinect-s...
