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.
