Revision history [back]

Problem solved! I was getting errors while starting move_base with DWA in a classical way because i forgot to install the proper package:

 sudo apt-get install ros-kinetic-dwa-local-planner

Now everything is working well.

For reference i set the local planner as DWA by adding this line to my move_base.launch file:

<param name="base_local_planner" value="dwa_local_planner/DWAPlannerROS"/>

I can then set the params with a *.yaml file:

DWAPlannerROS:
  max_vel_x: 0.4
  min_vel_x: 0.1

  max_trans_vel: 0.4
  min_trans_vel: 0.1

  etc....

Sorry for shooting to fast. But to be fair the documentation of the navigation stack is not very clear on this point...
