Ruby Examples
Using the RBC controller
You can download the Ruby-extension for controlling the Robobuilder using a GNU+Linux PC here:
Here is a small example program which makes the robot get up if it's lying on its back or its front.
#!/usr/bin/env ruby
require 'robobuilder'
require 'matrix'
class Vector
def norm
Math.sqrt inner_product( self )
end
end
robot = Robobuilder.new '/dev/ttyUSB0'
puts "Robobuilder"
puts "Serial number: #{robot.serial_number}"
acceleration = Vector[ *robot.accelerometer ]
if acceleration.inner_product( Vector[ 0, 0, 1 ] ) >
acceleration.norm * 0.97
robot.basic
robot.a
elsif acceleration.inner_product( Vector[ 0, 0, 1 ] ) <
-acceleration.norm * 0.97
robot.basic
robot.b
end
acceleration = Vector[ *robot.accelerometer ]
if acceleration.inner_product( Vector[ 0, 1, 0 ] ) >
acceleration.norm * 0.97
robot.run 1
end
robot.close
