Segaway up a steep hill

There is a renewed program for the NXT Segway called RobotC

The current program handles all balancing tasks in the background so you can make the Segway do what you want without worrying about balancing. It supports both the HiTechnic Gyro sensor and the new Dexter Industries dIMU. The complete source and instructions are available on my website.

The older ready to run NXT-G version of the program (only supports HiTechnic Gyro) is also still available.
