Description and Operation 4-5
•
Encoders on the drive motors to measure the driven distance.
•
Ultrasonic sensor to measure the distance to a wall or fence.
•
Gyroscope to measure angle differences to keep the right direction.
Encoders
Each drive motor has an encoder that counts the rotations of the motor shaft. This information is used to
calculate the position of the vehicle.
The encoders send outputs to the ADS3840 PCB.
Ultrasonic Sensor
The ultrasonic sensor makes sure the machine follows the wall or fence at a pre-determined distance.
A foam ring is adhered on the sensor to minimize reflections and to focus the reflected beam.
The sensor gets inputs from and sends outputs to the ADS3840 PCB.
Gyroscope
The gyroscope measures the turning angle. This information is used to find the correct direction. The
gyroscope is installed on the ADS3840 PCB.
Pause button
