"This module is only for controlling the SITL simulation with a joystick, not the actual ArduCopter.
Here is documentation on flying the actual ArduCopter with a joystick, via the Mission Planner: http://code.google.com/p/arducopter/wiki/Joystick"
I was working on getting the SITL simulation up and running this weekend, and was able to modify MAVProxy.py to support real-time control via a joystick or gamepad, here is the updated file:mavproxy_joy.pyIt requires installation of pygame…
"@Bradley, there is a 4-wire connector that sends the PWM servo signals from the APM to the power distribution board, and the mapping to motors can be changed by re-soldering the leads from this connector to the correct spots on the power…"
"The FTDI cable would be for programming an Arduino that does not have a built-in FTDI - This is not needed for the APM2 (as well as APM1) since they have this on-board, and only require a normal micro USB cable, which looks like it is included with…"
For 1), that is close to the right idea. The x and y accelerometers on a quad don't actually sense much on a quad because as it tilts, it also accelerates in a way that negates the acceleration of gravity to the sensor. Another way to…"
"What you're going for is known as "translational rate command" or TRC where aircraft velocity is proportional to the control input. This is a step up from the current attitude-command response that is implemented in STABILIZE mode. To truly do…"
"Many people are currently using Xbee radios for telemetry that are capable of communicating with a UAV beyond visual range. Using a cell phone would just be an alternate way of implementing the telemetry link (albeit with the potential for MUCH…"
"Matt, that's interesting, your altitude would definitely reduce performance - at a given rotor RPM, the prop will move less air, and you will get less thrust, but will also require less torque. Have you tried using a larger diameter or more…"
"Thanks for the advice - I will try running the motors for a longer time on the ground to see if that results in drift on its own. I do have some padding between the APM and the frame, but I have not yet soldered the bridges to enable the hardware…"
My AC2 is assembled, and I was able to do a couple indoor tethered test flights to make sure things are connected and setup properly. Here is the first test: This was somewhat of a success for the first flight, in that all of the electronics were…
"I think that brings up a really good point about APM reliability - do we know what would happen if each sensor or combination of sensors fail, and could an improvement to the code be made to detect and better deal with each possible failure?
"Krzysztof isn't trying to scare anyone - I agree that it is fine as long as you have a reliable backup (like manual mode) and don't fly to close to populated areas, but at the same time, the level of detailed testing and verification that commercial…"
