Malen - LEGO SPIKE Prime telephone game robot

Malen comes from Malentendu, which means misunderstanding in French.

The robot has a color wheel with 4 colors in the back and a color sensor in the front. When you show a color to the color sensor, it can show it back. You can chain multiple of these robots to make a telephone game!

Level C2 - Cooperation - Robotics with LEGO SPIKE Prime

The sixth level of the Robotics with LEGO curriculum is designed for students in third or fourth grade.

For the first time, two different robots are required to solve a challenge. Students learn how to cooperate, agree on a shared plan, and divide their roles. They build a variety of robots, including a crane that loads a sorter. Students also use two sensors at the same time to locate their target and to check whether their partner robot is ready to complete its part of the challenge.

Lesson 4 - Telephone game

Introduction

Today we are going to construct robots which will play the telephone game. Have you ever played it? What's the funniest word you've heard transform?

Picture of a figure whispering something in another's figure ear.

You all probably know how to play this game. The first player thinks of a word and then whispers it to the next one and so on. By the end of the line the word has become completely different and everybody has a lot of fun. How are we going to do that with robots? Instead of words, our robots will use colors and instead of ears – color sensors. The first robot shows a color to the next one which shows the same color, or at least tries to do so, to the next one and so on. Pay attention that robots should stand still although they are equipped with wheels.
