They are a polish team, and I think their bot is C++ based on a homegrown PCB. They have two microcontrollers onboard. One exclusively for sensors, and one for motors.
It's just a matter of time: C# will definitely beat C++, and the world will be a nice place to live...(and programming machines will be feasible without brain transplant)
In april there'll be a couple hundred robots in Wien for an annual competition. Robotchallenge.org. I haven't been there yet, but can hopefully go next year.
April in Wien? Really? Do you mean this year (2015)? At the end of April I should travel very close to Wien: let me know the details...
