Hi @qboticslabs , the moveit_simple_grasp has release the version of Kinetic, I can compile it well, but it can't load the param of grasp data yaml. `siarobot@siarobot:~$ roslaunch moveit_simple_grasps sia_7f_grasp_generator_server.launch ... logging to /home/siarobot/.ros/log/716b4258-bd0f-11e7-8bfc-001aa0e11420/roslaunch-siarobot-28298.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.
