2012-08-21 08:17:53 -0500 | commented answer | how to access old transforms tf The python API is very thoroughly buried so I'll post it here to save the next guy some time. TransformListener.__init__ takes two positional arguments. The first is boolean, whether to interpolate, and the second is length of the transform cache (rospy.Duration) |

2011-11-04 03:30:19 -0500 | asked a question | How do I find specific planner configuration options? Basically, I'd like to re-ask this question. I would like to run some benchmarking tests using several of the planners available in ompl. I would also like to be able to experiment with different configuration options for those planners. But in order to populate ompl_planning.yaml, I need to know what those options are named, and presumably this will vary by planner type. How do I find this out? |

2011-07-28 08:02:43 -0500 | answered a question | Joint publisher with empty velocity and effort vector I'm having the same problem. It seems like, in its current form, joint_state_publisher is incompatible with motion_planning_common. Is there a workaround? The project page suggest that one can set default values but doesn't elaborate on how. |

2011-07-26 09:16:38 -0500 | answered a question | Waiting for action server when using SimpleActionClient I'm having this problem too. I'm running diamondback (1.4.8). I can produce it with pretty recently checked-out pr2 stacks with the following
This hangs on line 10: move_arm.waitForServer(); roswtf tells me that all the move_right_arm subscriptions are unconnected. rostopic echo move_right_arm/* doesn't give me any messages either. Can someone confirm this? I followed the relevant tutorials to the letter. I would very much appreciate any debugging suggestions. Thanks, Tom |
