NXT

A ruby gem for controlling Lego Mindstorms NXT 2.0

Installation

Either install it from the command-line:

$ gem install nxt

or add to your Gemfile and install it:

source "https://rubygems.org"

gem 'nxt'
$ bundle install

Usage

The most basic usage can be done using the NXT class by connecting your NXT 2.0 brick over Bluetooth. In the examples below, the brick is connected at /dev/tty.NXT-DevB:

require 'nxt'

nxt = Nxt.new('/dev/tty.NXT-DevB')

puts "Connecting..."
nxt.connect

puts "Moving what is typically the right wheel one rotation..."
state = OutputState.new :port => :c,
                        :power => 55,
                        :mode_flags => OutputModeFlags.MOTORON | OutputModeFlags.BRAKE,
                        :regulation_mode => :motor_speed,
                        :run_state => :running,
                        :tacho_limit => 360  # degrees = 1 rotation

nxt.set_output_state state
nxt.disconnect
