Problem loading Stl in rviz
Hello everyone I am new to ROS and using Ros indigo with UBUNTU trusty I tried to make a urdf with my own stl and tried to run in rviz(latest version), but it showed the following error. I am posting the error and aunch file below. kindly help.
The error is :
UnboundLocalError: local variable 'slider' referenced before assignment
[joint_state_publisher-2] process has died [pid 3003, exit code 1, cmd /opt/ros/indigo/lib/joint_state_publisher/joint_state_publisher __name:=joint_state_publisher __log:=/home/xeon74/.ros/log/9a85b020-9749-11e6-b2c4-1cc1de334fec/joint_state_publisher-2.log].

and my Launch file is :
<launch>
<arg name="model" />
<!-- Parsing xacro and setting robot_description parameter -->
<param name="robot_description" textfile="$(find my_robot)/urdf/my_urdf.urdf" />
<!-- Setting gui parameter to true for display joint slider -->
<param name="use_gui" value="true"/>
<!-- Starting Joint state publisher node which will publish the joint values -->
<node name="joint_state_publisher" pkg="joint_state_publisher" type="joint_state_publisher" />
<!-- Starting robot state publish which will publish tf -->

<!-- Launch visualization in rviz -->

</launch>
Edit: Thanx for reply, I checked the file system and found the file ls -la /home/xeon74/my_bot/src/my_robot/mesh/stl/base_3.stl . Also I have installed joint_state_publisher from ros.wiki site under the complete package installation.
May the error is due to the .STL and .stl formats. Kindly suggest a way to correct this problems.
Edit2: Here's the output of the command
ls -la /home/xeon74/my_bot/src/my_robot/mesh/stl/base_3.stl
-rw-rw-r-- 1 xeon74 xeon74 23784 Oct 20 17:59 /home/xeon74/my_bot/src/my_robot/mesh/stl/base_3.stl
regarding the confusion between .stl and .STL , I was saying since Linux works under case sensitive environment , so will there be any problem using .STL instead of .stl ???
Edit3: Sorry for the wait. I was on vacation. I actually figured out the problem . Actually the problem was due to the loading of the single link in rviz without any joints and in the launch file I launched the ...

Hi, I meet similar problem like you. I draw a model file using sketchup, and convert it to stl using mashlab. This model file can be displayed in gazebo but get this "UnboundLocalError: local variable 'slider' referenced before assignment" error when loading in rviz.
