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.

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".

This is the robot that we use to demonstrate a solution for competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition. But after the competition we try to make a review and to see how we could have accomplish it. Our goal is to be better for next year.

This robot is quite powerful. The attachment mechanism on the front is one of a kind as it can do several things with a single motor: it can lift, it can unlock, it can grab. All of this thanks to the unique mechanism of gears

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.

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
