Vision processing and obstacle avoidance

The Trossen Robotics folks have a very interesting item on their blog:

Roborealm is hands down one of the most incredible tools available to roboticists today and amazingly it’s completely free, as in free beer Roborealm is a vision processing platform for Windows that allows experimenters to harness basic webcams and wifi cameras for use in robotics. We’re not just talking about telepresence here, Roborealm allows you to filter and manipulate video, as well as get output variables for use in various programming languages and even built-in hardware interface modules SSC-32 servo controllers, joysticks, etc.
