• Line following

This simple robot is designed to demonstrate the most basic line following methods, primarily the wobble or "ducky" line following method.

This is a complex three parts attachment for the FIRST LEGO League 2020 Replay competition mission called Boccia. The attachment does three things in the same time. It can align to a mission model, It has a contained for boxes that should be dropped and it also has a lever to rotate the boccia target mission model. On top of the that the attachment is working 10 out of 10

This is a LEGO Education SPIKE Prime robot attachment for accomplishing the FIRST LEGO League 2020 Replay Boccia mission . The attachment is designed for Gazon, LEGO Education SPIKE Prime competition robot.. With this attachment we follow the line with the robot until we reach the team mission and we use the lever on the top to push the blue box. Then we follow the line to reach the Boccia mission, and three things happen: 1. align to the mission model with the front of the attachment, 2. turn the lever to release the green boxes and 3. move the lever to push on the mission model. This is a complex mission requiring a lot of coordination from the robot. Quite interesting I must say.

Calix comes from Latin, meaning cup.

Calix is a robot designed to carry small objects—like a cup—while autonomously following a black line. When most people think about robotics, they imagine machines helping with household chores. Calix is a simple example of that vision brought to life. You can place a cup on it in the kitchen, and it will deliver the cup to the end of the black line!

The robot is powered by two SPIKE Prime medium motors for movement, and it uses a color sensor to follow the line precisely. At the front, a large motor connected to a gear system lifts and lowers the cup, allowing for easy pickup and delivery.

Calix is an elegant demonstration of how even simple robots can be designed to perform useful tasks—making robotics more approachable and practical for everyday life.

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.
