#node-myo
This is a prototype app that controls the Parrot Rolling Spider with MyoJS and PebbleJS
##Acknowledgments
Without the open source projects and guidance from [Chris Willians](https://github.com/voodootikigod/node-rolling-spider) and [Sandeep Mistry](https://github.com/sandeepmistry/noble), this project would not have lifted from the ground (literally).
##Quick run down
This Nodejs app:
- Creates a server and listens for AJAX calls from Pebble.
- Detects keypresses in terminal and controls the drone.
- Connects to Myo and allow dron control.
- Uses socket.io by the client UI to interact with the drone.
##Instructions
###Prerequisites
- Pebble
- Myo
- Bluetooth 4.0 enabled device
- Rolling Spider drone
###Running the PebbleJS app
Build ```pebbleapp/pebblejs.js```as an app in [cloudpebble.net](http://cloudpebble.net) and push to your mobile
###Running the Node app
```
cd app && npm install
```
Running the app
```
npm start
```
Running the app without tunnel proxy (disabled PebbleJS)
```
npm run dev
```
Note: Make sure bluetooth is turned on and Myo USB receiver is connected
### Drone discovery
To discover the ID and name of a certain drone, use ```app/lib/discovery.js```
##GUI
A node express server is run, served with Jade templates. Open the following URL in your web browser
```
http://localhost:1337
```
The web page serves three purposes:
- Provide a Myo gestures representation, using a drone image.
- Provide the IMU data output by Myo (Gyrocope, Accelerometer and Orientation). Outputs the reading every 250ms.
- Provide calculated Pitch and Roll data
- Output selected commands/operations being called behind the scene e.g. SocketIO is connected, etc.
__Note:__ This is still a work in progress. A lot of keypresses are not ported over to the GUI. For the time being, it only displays the following detected gestures from Myo: tilt left, tilt right, takeoff and land

##Known issues
- There is a small delay in time between nodejs calls and the drone responding to it.
- Unresponsive drone once it lands or crashed. The current fix is to reset the drone and restart the app
