During the 2020-21 season, we had many different mod designs for a base robot. Because this season was remote, we only had two members that were able to work on the robot.
Line Following
Line Following
We have a Proportional Line Following (PLF) program that we found in a book about EV3 coding. It follows in between the black and white lines on the mat using the reflected light intensity:
Black = 0
White = 100

Color Sensor Calibration
Color Sensor Calibration
We have a program to tell our robot what is black (0) and what is white (100). The reason we need this is because in different light conditions our programs may not work.

We found both our Line Following and Calibration from a book called "Winning Design!"
Navigation Points
Navigation Points
We created a system called navigation points it allows the robot to know exactly where it is. One great example of this is our touch sensor stick for Elevator. When the stick hits Elevator the sensor is activated, the robot stops, and then proceeds to flip over Elevator, now we know exactly where the robot is, so we get more consistent results.
Margin of Error
Margin of Error
Margin of error is how much room there is for error each time you run the robot. For example, if you line following to Traffic Jam your robot could be on the right, middle, or left side of the line. That is the margin of error, from the left side of the line to the right. This is because your robot can be in between any point with the margin of error. Part of our strategy is to minimize the margin of error as much as possible.
