2013-04-11 09:42:31 -0500	asked a question	trex in ros fuerte Hi there....... has anybody here worked around on T-Rex..I started working on this. I studied that the Pr2 milestone has used the T-Rex for its higher Level planning part. I am currently using ROS fuerte. I have installed T-Rex from https://code.ros.org/svn/wg-ros-pkg/branches/trunk_cturtle/stacks/executive_trex . I think the Trex is not supported beyond Cturtle. But I need to know about T-Rex. So if anybody worked on Trex before please help me. It will be highly appreciated. (The main problem is the Trex_ros package is not building...if anybody can guide me how to build it in fuerte, that will do the trick for me)

2013-03-16 04:38:41 -0500	commented answer	House_hold objects database @Amal....................I think for modifying the file pg_hba.conf, you should go to the root or sudo user, then you can edit or access the file.
2013-03-16 03:33:03 -0500	answered a question	where is the kinect place to measure? You should measure from the Depth camera of the kinect. It is the middle camera in the kinect. If you are facing the kinect, the left one is the IR projector, the middle one is the IR receiver or the depth camera, the right one is the RGB camera or the normal camera we generally use in our project. If you can see the URDF of the Kinect, the frame which is been defined as kinect_depth_optical_frame, that is the frame, from where you should measure your distance. Hope it helps.
2013-03-16 03:23:14 -0500	asked a question	how can I run pick_an_place on non-pr2 robot? I have created a robot which has two dynamixel based arm. I am using a kinect in the head for sensor perception. I can manipulate my arms by /follow_joint_trajectory and also from arm_navigation.launch file which has been created by planning_description_configuration wizard. I can also manipulate the arm using warehouse_viewer. I have checked the pick_and_place_demos by PR2 in gazebo. But I find this really complex. Can anybody guide me step-by-step that how can I do same type of work on my non-PR2 robot???
2013-03-16 03:17:53 -0500	asked a question	How can I simulate dynamixel arm in gazebo? I am trying to simulate my robot in gazebo which has dynamixel based arm. I am able to manipulate my robot arm by kinematics as well as by motion planning. But I want to create some pick_and_place task in gazebo with my robot. I have included the arms in my URDF. Spawing the robot in gazebo does not make the arm stiff. While the robot is moving, the revolute joints of my robots are also moving with external force. How can i get topics of my individual arms or individual motors. Topic like this /arm_controller/follow_joint_trajectory or /arm_shoulder_pan_joint/command.
