LEGO Education SPIKE Prime

This program makes Larvy - LEGO SPIKE Prime larva robot move forward indefinitely! The movement of this robot is very interesting as it works like a caterpillar or larvae! The program works by repeating 3 movements every cycle of the loop:

1. the front motor rotates for 90 degrees, rising or collapsing its wheels
2. the large motor rotates for 90 degrees, contracting or expanding the robot
3. the back motor rotates for 90 degrees, rising or collapsing its wheels

You may notice that every movement command does two things, or the same thing but a different direction. That is done using a variable that is either 1 or -1, and that gives the direction that the motors should move. This variable is also used to determine which motor should use full power and which shouldn't so that the robot doesn't break itself!

In this program we demonstrate how to program a SPIKE robot to follow a line with the aid of a color sensor. Make sure the line is big enough for the sensor to detect it and react to it. For some thinner lines, the speed of the robot can be lowered, but if that does not help, the program can be easily adapted to work with reflected light intensity.

This program was intended for and tested on the Gazon robot

This program was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot with the Cargo Connect M09 Train Tracks attachment. It is meant to help the robot complete the 9th mission of the FLL Cargo Connect competition.

The program uses the light and color sensor along with the motion sensor to accomplish the mission. It contains a few interesting tricks on detecting lines and configuring the behavior of the robot with specific params.
