The fourth level of the Robotics with LEGO curriculum for students from fifth to twelfth grades.

In this level students focus on the rotational sensor that is part of every motor in the robotics set. Students also learn to use the fourth sensor in the robotics set - the gyro sensor.
First few robot constructions imitate sea-animals and their behavior. Students create programs that check whether the robot's claws or pecks have successfully caught an object. That sensor in the motors allows the robots to go back in their lairs even after the use of unlimited movement. The rest of the robots are modeled after boats, yachts, and ships. With the help of the gyro sensor, students can set a course for their robots to a given angle and can detect deviations from the course. In open seas, there may be sea-monsters and the robots are being programmed to detect a sudden change in acceleration with the help of the said sensor.

This is the fifth level of the Robotics with LEGO curriculum for students in fifth to twelfth grades.

In this level students will learn how to work with data measured by the sensors. The concept of Algorithm is introduced and the programs perform calculations without knowing the values beforehand. The programming blocks transfer data between each other via data wires. The robots are designed to address the problems of security systems. Variety of alarm systems are built and the physical principles of different security methods are considered.
