Not able to specify use_slip_controllers:=true in pr2_tabletop_manipulation.launch [closed]

asked 2013-02-26 00:25:23 -0500


I am using ROS electric on Ubuntu 11.10 with PR2 robot in simulation.

I am able to do object manipulation without setting use_slip_controllers:=true. As given at :

But when I try to set this parameter to true I get an error as:-

$ roslaunch pr2_tabletop_manipulation_launch pr2_tabletop_manipulation.launch use_slip_controllers:=true
... logging to /home/nirala/.ros/log/61f677d0-800a-11e2-91bc-7071bc63a65c/roslaunch-nirala-desktop-20625.log
Checking log directory for disk usage. This may take awhile.

Machine [c1] already added and does not match duplicate entry


Kindly let me know how can I fix it (or is it fixed in later releases). In normal operation the grasped object (a cup) slips from the robot arm after some time. I was hoping that this might be helpful in fixing it.

I googled it and tried to make changes (grouping the tfs for different arm) as given at : but it also didn't worked.
