Hi I am new to robotc but I have used programing languages like labview with the nxt toolkit in the past. I was wondering if someone could provide some code for the nxt to make a segway without gyro drift. I would be very pleased if someone could do that.

there is a program for a segway in the sample programs. If you installed the software in the standard directory, you find the program there.
