Microsoft announced the availability of Microsoft Robotics Developer Studio (RDS) 2008 R2.
As given on the Microsoft site,
Robotic Development Studio is a software development kit for creating robotics applications. It provides the basic infrastructure for building applications that are highly concurrent and allows them to be distributed across multiple computers in a network by using a message-passing framework. At the lowest level, programmers can write the equivalent of device drivers for sensors and actuators. However, a primary function of RDS is to orchestrate higher-level services so that they can interact with each other to implement complex behaviors.
