In the above example, we cause the robot to rotate in place by a specified angle
by using
• void rotate(double degrees)
Moreover, we must have accurate values for wheelDiameter and trackWidth for
this method to produce accurate results. The diameter is the
widest measurement from one side of a circle to the other. In this project,
according to my measurement, it is 3.1 centimeters. In order to record
accurate rotations when the robot turns, it’s important to know the
measurement from wheel to wheel, called the track width. There should be a
theoretical point where the wheel touches the ground. Since we use the wheel
belt on our robot, its flatness makes it difficult to determine precise track
width. Since LEGO tires are symmetrical, the best way is to measure from the
center of one tire to the center of the other. In my program, I used 13.5 because
it works very well with my robot. You need to find an accurate number for
your robot. The final parameters for the DifferentialPilot are the motors
for the left and right wheels. In the above example program, the left motor
is connected to port A and the right motor is connected to port C.
1. Write a program to create a robot that traces out a square with sides of a
predetermined length, which is set to 1 meter in this project. You can
refer code of the example in the preparation part of this project.
