Errors showing the robot in gazebo

End-Effector commented 9 years ago

Thank you so much for this package!

I'm trying your package and when I roslaunch the gazebo.launch I get several errors. The robot still loads but some pieces are missing. I'm using last version of ubuntu and ros-indigo with gazebo_ros.

List of errors & warnings:

I investigated and I fixed the ERRORS.

In file pioneer3dx_wheel.xacro line 108 change to this:

  <joint name="base_${suffix}_wheel_joint">
  <hardwareInterface>EffortJointInterface</hardwareInterface>
  </joint>

because of this: http://answers.ros.org/question/186681/no-valid-hardware-interface-element-found-in-joint/

Parts of the robot are still not showing up. Like the yellow wheels caps...
