Until now, we have been controlling and interacting with robots from the command line. What about creating a frontend GUI? If your robot is in a distant location and you want to visualize and control it through the web, this chapter can help you. This is the final chapter of this module, and deals with building a cool interactive web application based on ROS and controlling a robot using it. The projects in this chapter can be mainly used for creating a frontend robot commander in your browser. We'll discuss a few projects using the ROS web framework. Here is a list of the projects and topics we are going to cover in this chapter:

• Getting started with ROS web packages
• Setting up ROS web packages
• Teleoperating and visualizing a robot from a web browser
• Controlling robot joints from a web browser
• Robot surveillance application
• Web-based speech-controlled robot application
