Algebraic Functions

SAM is a stepper motor robot. Stepper motors turn in small increments called "steps". The calculator programs SAMGOST and SAMPIVST allow the user to tell the motors how many “clicks” or steps to make. Students will soon realize that it would be more practical for the programs to allow them to input a distance in inches or centimeters. To do this, a function will be needed to convert distance D into steps S. In the end students will be challenged to program SAM to follow a path and park in his garage!
