Hello David, Could you give me a hint, what might be wrong?

rate of velocity commands seems to be decreasing. rostopic hz /navigation/cmd_vel gives me subscribed to [/navigation/

I need to check it. I will report it tomorrow. It is already night here. Does poor localization affect navigation?

Apologies, here is the zoomed version showing local path (green) and global path (blue). What I find strange is that the

Hi,

i am using 5DOF robot and i want to generate IK fast plugin for my robot. I have already generated my robot.dae file. But when I try to get IK solution using this command below

 python `openrave-config --python-dir`/openravepy/_openravepy_/ikfast.py --robot=igus1.dae --iktype=translationdirection5d --baselink=2 --eelink=6 --savefile=/home/pravin/catkin_ws

then i get this error.
