RPLIDAR ROS package

2D Laser Scanner (LIDAR) ROS node. Broadcasts each scan result into a ROS topic. Each result conceptually looks like this:

       xxxxxx
       x     xxx
       x       xx
       x         x
       x          xx
       x           xxxxxx
       x                xxx
    xxxx                  xx
   xx       o              xx
  xx                        x
 xx                         x
xx                         x
xx    xxxxx               xx
 xxxxxx   xxxx          xxx
             xxxxxxxx  xx
                    xxx

Where:

• the o is the lidar sensor itself ("origo")
• each x is a distance (= a single number) from o
