RESTful architecture of Microsoft Robotics Studio « Jon Udell

Ran across Jon Udell's screencast on the Robotics Studio and is' RESTful architecture...I've seen the demos in person and they are quite impressive.  Also, I've run across a number of folks that have used the Robotics Studio infrastructure for modeling other processes outside of robots...even scientific models.  I think it's quite an interesting system to investigate for working on scientific problems.  I'd be quite interested in hearing about those explorations... 

Henrik Frystyk Nielsen on the RESTful architecture of Microsoft Robotics Studio

Henrik Frystyk Nielsen used to work for the World Wide Web Consortium on some key pieces of infrastructure including the HTTP specification and libwww. He left the W3C in 1999 and now works for Microsoft where his current project is Robotics Studio, whose tagline is: “A Windows-based environment for academic, hobbyist and commercial developers to easily create robotics applications across a wide variety of hardware.” What that description doesn’t tell you, but today’s screencast shows, is that the Robotics Studio is based on a RESTful architecture, and that applications are built by composing lightweight services in ways that will be instantly familiar to every web developer.

To drive home that point, much of the action in this screencast occurs in a web browser, where you’ll see Henrik explore a distributed directory of services and view XML snapshots of the current state of bumpers, cameras, and laser range finders.

From a read-only perspective it’s all HTTP GET, and you can do things like subscribe to robotic sensors using RSS feeds. When you control a robot, SOAP is used to optimize fine-grained updates. But either way it’s a loosely coupled and late bound system that leverages the fundamental flexibility of web architecture in a very different domain. In one compelling demonstration of that flexibility, you’ll see a generic controller — which had been controlling the robot in Henrik’s office with no prior knowledge of the device, purely by interface discovery — switch over to a simulated robot and drive it by means of the same kind of discovery.
