Hi everybody, I am currently (still) in the process of porting the arm_navigation stack to a Katana arm. I already have a replacement for almost everything in the pr2_3dnav/right_arm_navigation.launch file (mostly a big copy-and-paste orgy, followed by s/pr2/katana/g). At the moment, I use the generic arm_kinematics package from urdf_tools to provide the get_ik and get_fk services, since this seems to be the simplest package to set up. Maybe later I'm going to switch to OpenRave's ikfast module. However, move_arm expects a get_constraint_aware_ik service. Is there an easy way to get that going? Cheers, Martin -- Dipl.-Inf.
