#Introducing the Robotic-arm gem

This gem controls the USB OWI Robotic arm.

• You will need to apt-get at least 1 libusb package if I remember correctly. It might be libusb-dev but I can't be certain.

require 'robotic-arm'

ra = RoboticArm.new
ra.led.on
ra.shoulder.up 0.5
ra.elbow.up 0.5
ra.wrist.up 0.3
ra.base.left 0.7
ra.gripper.close 0.2
ra.gripper.open 0.4
ra.led.off
ra.stop

Note: The user must have permission to use the libusb device. You can run the above code as root.
