Gyro Sensor(GS-12)

New Sensor

Introduction

  • Measures angular velocity.
  • Calculates which side the robot is tilted or is getting more power.
  • Maintains the robot’s balance and can be used for other movement applications.

Sensor Output

New Sensor

Item MAX ~ MIN
Output Value 510 300 100
Angular Velocity +300°/s 0°/s -300°/s
Voltage 2.5 V 1.5V 0.5V

Standard VCC Voltage Value is 5V.

Old Sensor

Item MAX ~ MIN
Output Value 455 250 45
Angular Velocity +300°/s 0°/s -300°/s
Voltage 2.23 V 1.23V 0.23V

Standard VCC Voltage Value is 5V.

  • When the angular velocity is 0 (when still), the output value is approximately 250. When it suddenly turns to one axis, the max value output is 455 and the minimum 45, showing a 300°/s angular velocity. Here the mark or sign represents direction.
  • Depending on the temperature, there may be 1% difference.
  • There may be a difference in value depending on the standard VCC voltage value and circuit noise. Thus, we recommend to average several values before use.(When sampling, the robot must not be moving.)

  • You can READ the value using the User’s Device Parameter in RoboPlus Task.

  • You may sample it out like below. It reads 10 values per 0.1 sec and makes an average. This value can be used as the standard value.
