rosbridge in 10 minutes video tutorial
Having trouble using ROS with your robot in ROS in your favorite environment (e.g. Windows, Arduino, web browser, Android, iPhone)? If so, rosbridge provides a means to use all of what ROS has to offer purely through network messaging.
Trevor has posted a great video tutorial for no-frills lightweight usage of rosbridge from the command line. Just by sending simple JSON formatted strings, you can publish and subscribe to ROS topics, perform introspection, and more. The video assumes familiarity with Unix command line tools and publish-subscribe messaging in ROS.
