Today Microsoft’s robotics group announced the release of the Microsoft Robotics Developer Studio 4 Beta. This beta has extensive support for the Kinect sensor hardware which is much awaited from developers through the Kinect for Windows SDK allowing them to create Kinect-enabled robots in the Visual Simulation Environment and in real life. Along with this release comes a standardized reference spec for building a Kinect-based robot. Channel 9 did a first look video of a robot called "Eddie" from Parallax Inc.
This robot can be purchased through their online store after sometime. You can download RDS 4 beta at Microsoft.com/robotics.
