2014-01-28 17:21:56 -0500 | marked best answer | nodes with 2 computers Hi, I am trying to make a node on one computer(computer A) with some publishers and some services and try to read the messages and call some services with another computer(computer B). computer A(ip is 192.168.1.100) and computer B(ip is 192.168.1.101) are connected since they can ping each other computer A runs a roscore since it is the master. on computer A, I set the ROS_MASTER_URI at http://localhost:11311 on computer B, I set the ROS_MASTER_URI at http://192.168.1.100:11311 and the ROS_HOSTNAME at 192.168.1.101 and yet it doesn't work, I don't even receive the topics messages, I am sure I am doing something wrong or maybe didn't configure my network properly. Does someone happen to know how to solve the problem? Thank you so much for your help. edit : Just for updates, when on the computer B I do rostopic list I receive the list of topics that is running on the computer A, so the configuration is good. However, I didn't try for the services, but on the computer B I can't receive the image coming from a kinect that is on the computer A. Did anyone have this problem before? |

2012-02-22 22:49:05 -0500 | answered a question | Slam gmapping problems Hi Hunter, As Stefan said, you can look at the well made tutorial. Also if you are interested you can take a look at the launch file named gmapping.launch in the package corobot_state_tf, that is made to run gmapping on a Corobot. It may help you to understand how to launch gmapping. You should even be able to record the map in your bag file by launch this launch file. |

2011-12-27 08:39:37 -0500 | marked best answer | Download a package with rosmake rosmake is not designed to download and build packages. It only does the building part. I suggest that you look at using rosinstall to install your packages. |

2011-12-26 09:01:57 -0500 | asked a question | Download a package with rosmake Hi, I created a stack which includes one teleop package. this package uses the library Qt and depends on the stack eros to build it. In the current state, before building my package, I need to install the eros stack by following the installation instruction: http://www.ros.org/wiki/eros/Installation I included the necessary eros_build package as a depend in my manifest.xml, but that doesn't download and install this package or even the eros stack. My question would be, is there a way to automatize the download of the eros stack while executing rosmake in my package, if the stack wasn't found? Thank you for your help. |

2011-12-01 11:20:28 -0500 | commented answer | Time needed for complete urdf model? I think I can get the measurements without too much troubles. I would prefer to have meshes, I think the result will be better, especially for the arm and the gripper. After looking a little more at the details of the urdf package, I you made a good estimation, if I do some very simple shapes only. |

2011-11-30 13:43:02 -0500 | asked a question | Time needed for complete urdf model? Hi, I would like to make a URDF model of a robot to simulate it in Gazebo. However, it seems like a lot of work to do this model from scratch. I know that there a very good tutorial exists, but is there like a database of existing URDF models from which we could start with? I know about the erratic and the PR2 robot, are thee some others? Also, from your point of view, how much time of work is needed to make a complete model of a robot with 4 wheels, 1 arm, 1 camera, 1 Hokuyo, some bumper sensors and some infrared sensors? Thank you so much for your precious help, Regards, Morgan |
