Objective
To calibrate a moving robot to relate the angle of rotation of the motors to the distance moved.
Need for Calibration
The relation between the distance moved by the robot and the number of rotations of the motors is dependent on the size of the wheels and the gears (if any) used in transmission. To make the robot move by a particular distance is more meaningful to know, and is easier to standardize over different robots, than the rotations of the motors. This exercise deals with measuring distances traveled and mapping them to the number of rotations of the motor.
Method
Based on the previous program, make the robot move corresponding to different degree rotations of the motor and measure the distance traveled by the robot for each setting of the angle. Make at least three such measurements and use Excel to plot and fit a line to the results (this will be explained in class.)
If the data has too much scatter, you might want to collect more data.
