CrazyFlie control software
A node.js control library for the Crazyflie nano-copter. This is a work in progress! Your contributions are more than welcome.
libusb is required for the radio driver. On OS X, install with homebrew:
brew install libusb
Then install Aerogel:
npm install aerogel
Aerogel uses new-style node streams so it requires node 0.10.x or later.
copter object is what your control scripts should manipulate.
A simple script for taking off then landing again immediately looks like this:
var Aerogel = require'../index';var driver = ;var copter = driver;processon'SIGINT' copterlandbindcopter;driverfindCoptersthenif copterslength === 0console.error'No copters found! Is your copter turned on?';processexit1;var uri = copters0;console.log'Using copter at' uri;return uri;then return copterconnecturi;then return coptertakeoff;then return copterland;then return coptershutdown;done;
The protocol driver emits telemetry information as events that the copter object listens for. The handlers for these events don't do anything yet, but the plan is that they'll eventually be used to implement higher-level flight control constructs & autonomous goal-seeking.
copter.handleStabilizerTelemetry() gets an object with three orientation fields:
copter.handleMotorTelemetry() gets an object with the state of the four motors:
Aerogel exposes a promises API at the moment. Eventually I plan to offer a standard callback API as well. If you do not pass a callback to a method, a promise is returned.
