The LEGO Mindstorms EV3 Gyro sensor was one of the new sensors in the EV3 sets. In this course we walk you through the basics of using and programming the sensor. The sensor detects when the robot construction turns at a particular angle, but there are a number of gotchas in using it. The Gyro Sensor is useful with almost any robot construction. If you use it during competitions like FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) it would be much easier for you to accomplish more missions in the given time. What the sensor does is to detect the Angle of rotation of the construction and the Rate at which the robot is rotating. The rate is in Degrees per second. How fast is the robot moving.
