• Line follow

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

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. since we are measuring reflected light rather than the color of the line, we can and have implemented multiple states line following.

In this program we demonstrate how to program a SPIKE robot to follow a line with the aid of a color sensor. In this program, we use the sensor value to calculate a number to feed in the "start moving" command. The numbers in this program depend highly on the size of the wheels of the robot, the distance between the wheels, the color sensor reflected light range, the wheels friction, and the speed at which the robot moves. The numbers in the program must be adjusted for every case, and are in no meaning optimal to use as is, in other projects.

In this program we demonstrate how to program a SPIKE robot to align to а line with the aid of two color sensors. Make sure the line is big enough for the sensor to detect it. For this program to work, the sensors must be placed in front of the wheels.

In this program we demonstrate how to program a SPIKE robot to align to а line with the aid of two color sensors while moving backward. Make sure the line is big enough for the sensor to detect it. For this program to work, the sensors must be placed in front of the wheels.

In this program we demonstrate how to program a SPIKE robot to follow a line with the aid of one color sensor and detect an intersection with another 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.

In this program, we demonstrate how to program a SPIKE robot to follow a line with the aid of one color sensor and detect and stop at the second intersection with the aid of another 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.

In this program, we demonstrate how to follow a line with a SPIKE robot and then align to that line. That way the robot can position itself at specific distances on a predetermined path.

This program is for Calix - LEGO SPIKE Prime carrying robot. The robot is made to carry an object while following a black line. This is probably one of the first thought that comes to mind when you think of robotics - A robot that can help at home! This robot is made as a first try at this concept. It can move not too heavy objects from one room to the other, following a black line. The program does the following: First it waits for you to put something on the robot and to click the left or right hub buttons. After that it lifts the item a bit and starts following a black line. It follows the line until it sees the same color for more than 3 seconds, thats how the robot knows it has reached the end of the line! After that it rises whatever it is carrying and waits while keeping the object up.
