====== Monorail ======
===How to control the monorail===
You can control it from Python over Bluetooth as follow (instruction for a linux distro):

  - Install [[http://code.google.com/p/nxt-python/| python-nxt]] 
  - Turn it on by pressing the orange button.
  - Start python and run the following setup commands:
<code>
from nxt.bluesock import Bluesock
from nxt.motor import Motor
ID = '00:16:53:02:9B:DE'
sock =  BlueSock(ID)
brick = sock.connect()
motor_a = Motor(brick, nxt.motor.PORT_A)
motor_b = Motor(brick, nxt.motor.PORT_B)
motor_c = Motor(brick, nxt.motor.PORT_C)
</code>

You can then control the motors by calling motor.turn(power, degrees)
e.g. motor_a.turn(127, 360).

Motor A moves it along the rail, Motor B pans the sensor head and Motor
C tilts the sensor head.

See the python-nxt documentation for more, you should be able to set up
and use the sensors too.

===Parts===
The assembly parts for the track are stored in a christmas cardboard box. The box waits for you on a shelf beside the old batteries container. The design for the laser cutter of the ceiling station and connector is stored in [[https://github.com/HennyN/Hacklab_monorail |a github rep]]. 

<code>
Ceiling holders:      laser-cut from 3mm ply
Screws/threaded rods: M5
Rail:                 3x19x4000mm Aluminum
</code>

===Roadmap===
  * charging station
  * junctions

**Control Monorail From Android**

Download the lego NXT app, pair bluetooth with android device by matching the pin displayed on the screen of the lego brick. Pin was 1234. 

Motor A moves it along the rail, Motor B pans the sensor head and Motor
C tilts the sensor head.
