Quadcopters are obscenely popular and cool. It is like building your own intelligent UFO.

Build goals

  • Use open source hardware and software
  • Get something working and iterate
  • Pluggable capabilities
  • Have multiple people
  • Capable of a 250 g payload (GoPro + case + gimbal)
  • We should build a "virtual kit". That is base it off some on-line instructions, but not a real boxed kit and especially not a commercial pre-built product. This seems to cut the cost to a half or a third, though introduces risk.
  • Having several of us building the same thing so we can help each other solve problems. And we each get our own bot.
  • KwartzCopter project phases

Current questions

  • How are we going to deal with vibration, especially for the FPU?
 [http://copter.ardupilot.com/wiki/vibration-damping/ ArduPilot] suggests +/- 0.3G in X/Y and +/- 0.5G in Z.  We need to look into suspension mounts, tape, foam, etc.  Put some links here!
  • Which software do we want to run, and hence which processors?
  We're running ArduPilot-MPNG on an ATmega2560
  • What code changes do I need for the RC receiver?
 If you have an existing VM, edit ~/src/ardupilot-mpng/libraries/AP_HAL_MPNG/RCInput_MPNG.cpp
 
   #define SERIAL_PPM SERIAL_PPM_DISABLED
   ...
   #define RC_MAPPING RC_MAP_JR
  
 Note that newly created VMs already have this patch applied.
