Hi community, I tried to navigate the p3dx with navigation stack. I tweak with the base_local_planner parameter for the past 2 days but it does not seem to improve. This is what i get from roswtf Loaded plugin tf.tfwtf No package or stack in context ================================================================================ Static checks summary: No errors or warnings ================================================================================ Beginning tests of your ROS graph. These may take awhile... analyzing graph... ... done analyzing graph running graph rules... connection to [/rxplot_2558_1291289166766] timed out ... done running graph rules running tf checks, this will take a second... ... tf checks complete Online checks summary: Found 2 warning(s).

I try to echo odom when I was running navigation but nothing is displayed. I am using p2os driver to communicate with the base. I also notice that whenever i sent a goal, it will take some time (approx 20-30s) before p3dx start to move, it will move very slowly. Sometime when it reaches some distance, it will start to pause again. Any inputs are welcome.. thanks alot =D Cheers, Ian_wk -- View this message in context: http://ros-users.122217.n3.nabble.com/navigation-on-P3DX-very-slow-tp2005429p2005429.html Sent from the ROS-Users mailing list archive at Nabble.com.
