Every time we have used the gyro sensor so far we have measured the angle at which the robot turns. However, today we will make something different. Did you know that the gyro sensor does not actually measure the angle but the change in turn speed (acceleration)? Our robot is smart and it uses the acceleration to calculate the angle it is at. Unfortunately, it does not always calculate the angle correctly but it always calculates the correct angle acceleration. The calculation method is in the Rate mode of the gyro sensor:

The Rate mode can also be found in other blocks using the gyro sensor such as the wait block or the switch block:

Courses and lessons with this Tutorial

This Tutorial is used in the following courses and lessons

Robotics with LEGO - Level 3.0 - Security systems

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.

Lesson 4 - Seismic sensor

Introduction

In the following two lessons you will be the chief prison guard. Rumor has it that a gang of cake robbers is to be moved to your prison and they are planning to escape. In order to avoid a public scandal, the Mayor of the city has decided to invest in a new security system for the prison. Your job is to preserve the good name of your prison and protect the cakes in all pastry shops in the area.

Robotics with LEGO - Level 4.0 - Kinesthetic and Memory Game (in development)

The seventh level of the Robotics with LEGO curriculum for students in sixth or seventh grade.

In this level, student develop a memory training game. The player must remember series of actions like press a button, shake a pole, pull a lever, show one of many colors. In order to program the game, students use many variables and modify their states. Students create their own custom sounds and images, in order to reflect their own personality in the game. In the end of the level, the game stores top scores even after a full shut down with the help of text files.
