I want to share with the comunity, a simple program i made to calculate the wheel speed based on the diamater and speed of the motor used. I begin programing this little tool to calculate the speed of my upcoming robot based on the Pololu Micro Metal motor. The program it's free, no need for instalation (Windows only, sorry!) and show km/h and meters/second.
