• Line following

Calix, from latin, means cup. Calix is made to carry an object while following a black line. Most people, when they think of robotics, they think of how the robots may help them at home, with the chores that no one wants to do. This robot is a simple version of this. You can give it a cup in the kitchen and then it will deliver it to the end of the black line! The robot uses two SPIKE Prime medium motors to move and a color sensor to follow a line. At the front it has Large motor with a gear system that lowers and rises the "cup".

Umjaho - from the language of the Zulu tribe. It means "competition"

This LEGO Mindstorms EV3 robot has three sensors - touch, color and ultrasonic. When the touch sensor is pressed the robot starts moving. The color sensor is used for following lines and the ultrasonic sensor is used to detect any robots in front of the robot. 

This is the simplest possible line following robot. It has just one sensor in the front between the two driving wheels and uses beams as pivots instead of a third wheel. Try it out. Follow the building instructions and start following lines in a number of minutes.
