Product Usage

• 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.

Pin Layout Information

[ X Axis Pin ]

1. ADC : Outputs the angular velocity into analog signals.
2. GND
3. VCC ( 5V )
   
   [ Y Axis Pin ]
4. VCC ( 5V )
5. GND
6. ADC : Outputs the angular velocity value into analog signals.

Analog Signal Output in Regards to Sensor’s Environment

(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.
