 ### Test it with REEM
 
  * Open a REEM in simulation with a marker floating in front of the robot. This will start the stereo cameras of the robot too. Since this is only a vision test, there is nothing else in this world apart from the robot and a marker floating in front of it. An extra light source had to be added to compensate for the default darkness.
