This years MEDC Sumo Robotics competition is going to be based around Microsoft Robotics Studio 1.5 - the hardware is going to be based on the iRobot Create chasis and uses an ICOP eBox 2300 running Windows Embedded CE 6.0 as the embedded component of the robot.
You can get started developing and testing your Robotics code today by downloading the Microsoft Robotics Studio 1.5 CTP and the Sumo Robotics Simulator.
Here's the important information:
To take part in the MEDC 2007 Sumo Robotics competition you need to be at the MEDC registration area on Monday April 30th at 8:00am – during the day your code will be run in a virtual competition, the top 40 competitors will then move onto porting their code to run on the physical robotics hardware.
The Microsoft Robotics Studio team have a support forum for you to ask questions about developing using Robotics Studio.
Let me know if you have any questions...
