Hi folks: I've noticed that Player segfaults if you try to use it with the default Gazebo SickLMS200 laser model. The problem seems to be related to an incorrectly sized memory block in libgazebo. Until this is fixed, the workaround is to reduce the number of range readings generated by the laser from 361 (the default) to 181 (i.e. 1 degree resolution instead of 0.5 degree resolution). <model:SickLMS200> ... <rangeCount>181</rangeCount> </model:SickLMS200> This bug appears in all combinations of: Gazebo 0.2.0 and HEAD Player 1.4rc1 and HEAD Andrew Andrew Howard email: ah...@po...

Hi again: This bug has been fixed in Player HEAD and Gazebo HEAD. If you are working from one of the releases, however, you still need to use the work-around described below. A.
