The sixth level of the Robotics with LEGO curriculum 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 and find a common approach to the challenges and how to distribute their roles. Various robots are built, even a crane that loads a truck. Students use two sensors at the same time so that they find their target and find out whether their partner-robot is ready with their part of the challenge.
Today we are going to construct robots which will play the telephone game. You all 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.
