2015-02-02 04:43:21 -0500 | asked a question | Which path planner is chosen if unspecified? Hi, I am using ros-groovy with the ur5 package and I would like to get some information about the path planners. First is, if I do not specify a specifiy path planner, which one is being chosen? Or is there a default one? And second (still no specific solver chosen), after the path planning, can I get the name of the solver which was being chosen? I would like to do a performance benchmark of the various solvers. |

function1 does not have return values so if function1 looks like:
,I can not access message.getData() in the original script. So how can I do that? |

2015-01-09 07:24:38 -0500 | asked a question | Matlab support for groovy Hi, I am using the groovy distribution and I would like to communicate with Matlab through the ROS I/O package. On the Matlab page it is stated that hydro is necessary. Does anyone have experience if groovy works as well ? Fabian |

2014-12-09 05:16:23 -0500 | asked a question | tf, translation between frames Hi, I have a setup with multiple target frames. Now I want to get the position of my last frame in relation to the world frame. During execution typing rosrun tf tf_echo /world /LAST_LINK I receive exactly what I am looking for - Translation: [20.632, 0.000, -3.759] - Rotation: in Quaternion [-0.574, -0.000, 0.819, 0.000] in RPY [-0.000, 1.222, 3.142] How can I read these values in my program in order to perform further calculations from it? |

2014-10-10 02:34:38 -0500 | asked a question | path planning exceeding velocity limits of ur5 Hi, I am using moveit for path planning of a ur5. After finding a valid path, I want to execute it to the real robot (which is connected and communicating properly) but I always receive an error message like: the controller reports: any ideas how to fix that ? |

2014-10-08 05:02:04 -0500 | asked a question | constraint path planning ur5 Hi there, I am following this tutorial http://wiki.ros.org/Industrial/Tutori... in order to move my real ur5. So far I get the simulated robot running using the demo.launch file from https://github.com/ros-industrial/uni... . After specifying a desired end-effector position in the cartesian frame ( in the rviz gui) I often receive path planning which seems to be not very cost efficient. Furthermore, my robot will be mounted on a flat surface which means that the robot will collide in case any point is below z=0 of the base(world) frame. How can I constrain the path planning in order to only get paths wich are limited to my reachable task space? |
