Hello,

I am trying to create urdf file for the UR5 arm with the Barrett Hand end-effector. I have created this file:

<?xml version="1.0"?>
<robot xmlns:xacro="http://wiki.ros.org/xacro" name="ur5_bh" >
  <!-- include urdfs -->
  <xacro:include filename="$(find ur_description)/urdf/ur5.urdf.xacro"/>
  <xacro:include filename="$(find barret_hand_description)/urdf/bh280.urdf.xacro" />

  <!-- create the robot + bh combo itself as a macro -->
  <xacro:macro name="ur5_with_bh" params="prefix">

    <!-- instantiate -->
    <xacro:ur5 prefix="${prefix}robot_" />
    <xacro:bh      prefix="${prefix}ee_" />

    <!-- attach eef to M-10iA model -->
    <!-- Note: this assumes that the 'bh' macro defines a 'base_link'
        link which is the start of it's kinematic chain (if any) -->
      <!-- tool0 frame -->
  <link name="tool0" />
  <joint name="ee_tool" type="fixed">
    <parent link="_base_link"/>
    <child link="tool0"/>
    <origin xyz="0.0 0.0 0.0205" rpy="0.0 ${-pi/2} 0.0"/>
  </joint>

  </xacro:macro>
</robot>

When I run "check_urdf /home/ros/cats_ws/src/universal_robot/ur_bh/src/ur5_barret.urdf.xacro" It return this error:

Error:   No link elements found in urdf file
         at line 180 in /build/buildd/urdfdom-0.2.10+dfsg/urdf_parser/src/model.cpp
ERROR: Model Parsing the xml faile

Does anybody know how to solve this problem?

Hello,

I would like to set the workspace bound for my robot. I know there is a functionality in moveit that helps you to do that. It is called "fix workspace bounds". Anybody has some example code in python I could use to understand how it works ?

Hello,

I am looking for a way to attach end-effector to the UR5 arm I have tried setup assistant but I have not succeeded. My second problem is setting up the environment for the UR5 arm. The arm needs to be fixed on the wall of the cage which is constraining the arm movement.

Any suggestions would be appreciated. Thanks.

Hello,

I am trying to create web interface for Baxter robot. I've managed to create connection and live camera stream for one of the arms. I have pick and place sequence ready, and I would like to launch it by clicking a button on the web page. I am looking for a way to launch file or rosrun a python script through web page and display the information that I get in command window. I know that "ros-brown-pkg" would be useful for that, but I can't find it anywhere. Anybody came across tutorials or any documentation that might help me ? Anything would be helpful.

Turns out it was a package error. The bug is now fixed.

Hello,

I am trying to run the face_recognition package, as I follow the tutorial they ask me to publish video stream to topic /camera/image_raw. I am trying to do it with the image_transport package using command "republish" but when I run it in the command window it says republish: "command not found". Anyone familiar with this situation ?
