Can't move Robot with Web GUI and rosbridge

[Kim Nguyen]

I followed the instruction from ROSBRIDGE : BUILDING A WEB GUI FOR YOUR ROBOT in the book. I downloaded the code and package relate robot_gui.html. I got to the point that can bring the GUI through robot server, but it can't move or do anything. Here is the step that I have done:

1. I paste all the source code as it is instructed in the book include robot_gui.html, tabs/main.html, navigation.html, diagnostics.html, parameter.html, misc.html, js/robot.gui.js, styles/robot_gui.css
 to /var/www/html in the robot. My robot is Ridgeback from Clearpath, and my ros version is Indigo. I install apache2 as web server.

  sudo apt-get install apache2

2. In the robot terminal, i ran Rosbridge.  

roslaunch rosbridge_server rosbridge_websocket.launch

3.In other robot terminal, i ran 
rosrun tf2_web_republisher tf2_web_republisher

4. In web browser, I typed in ip address of my robot and it appeared the Web Interface, but it didn't move or respond to anything


Anyone have any advices on how to check if the code actually running and how to fix it? thank you

I ran command rostopic echo /cmd_vel and it give this output

Quick update from my question, I checked the console log from the web browser and it indicated that "WebSocket connection is fail.." . Any advice for this bug ?
