The default units for length and angles are meters and degrees
respectively. Units may be changed using the following global
The following example uses millimeters rather than meters for the unit length unit:
# This world file creates two robots with lasers. # It uses the 'include' statement to include the robot definitions. unit_length "mm" include "myrobots.inc" environment ( file "cave.pnm" scale 30 ) myrobot ( name "robot1" port 6665 pose [1000 1000 0] ) myrobot ( name "robot2" port 6666 pose [2000 1000 0] )Be warned that the length specfication applies to the include files as well, so choose a unit length early and stick to it.
