Robochamps is a huge Robotics programming contest based on Microsoft Robotics Developer Studio 2008 tools and technologies. This competition will allow you to participate in different challenges, playing with Visual Studio 2008, Robotics Developer Studio 2008 and amazing simulated environments. Imagine programming a robot that will have to fight another one, solve a maze, navigate on Mars, rescue people in an earthquake environment or drive autonomously in an urban area.
All the primary phase will be done on simulated environments, but the finals will take place at PDC in October with real hardware!
