2011-04-21 19:54:57 -0500 | marked best answer | pioneer 3dx simulation using rviz and stage RViz listens for TF messages, by default on topic /tf. That is the only way it knows where each part of the robot is relative to other parts of the robot. On my (simulated) system, /tf is published by nodes amcl, robot_pose_ekf, robot_state_publisher, and gazebo. Perhaps you need to run more nodes to fill in the missing TF frames. If nothing is filling in the /odom frame, you can try setting the "fixed frame" in RViz to /map or /base_footprint. For that matter, in my system I don't have a frame called /odom, I only have /odom_combined. Maybe that is the problem? |

2011-03-28 10:23:51 -0500 | asked a question | Issues with connecting SICK laser to the computer Hello all, I'm trying to connect the SICK laser to my computer and I'm following this tutorial: http://www.ros.org/wiki/sicktoolbox_w... I came across this problem: http://answers.ros.org/question/257/u... but I fixed it and now it doesn't stop indefinitely. However, there are still issues with connecting to the SICK laser this is what I get when I try to connect: I'm using ubuntu 10.10 with cturtle, also I have checked the proper permissions and I have the ports set properly: Any help would be appreciated. thanks, Vinay |

2011-03-04 07:57:45 -0500 | asked a question | pioneer 3dx simulation using rviz and stage Hi, I installed ROS on ubuntu 10.10 and I'm trying to simulate a pioneer robot on rviz. I have the usc p2os package and I'm trying to use the pioneer3dx.urdf for the robot simulation. The robot is recognised by rviz but the left, right wheels and hubcaps are not being recognised. I'm getting "no transform from [/...] to [/odom] error. Any help would be greatly appreciated. thanks, Vinay |
