4-8 Description and Operation
D-I012.1109EN
innovators in agriculture
The multiboard pcb sends outputs to the E-Link manual controller,
ultrasonic sensor, motors, encoders and inductive sensors.
The multiboard pcb gets inputs from the E-Link manual controller,
ultrasonic sensor, motors, encoders, inductive sensors.

Encoders
Each drive motor has an encoder that counts the rotation of the motor
shaft. This information is used to calculate the position of the vehicle.
The encoders send outputs to the multiboard PCB.
Ultrasonic Sensor
The ultrasonic sensor (1, fig. 17, page 4-9) makes sure the JUNO 150
follows the wall or fence at a pre-determined distance.
A foam ring (3) is attached to on the sensor to minimize reflections and
to focus the ray beam.
The sensor gets inputs from, and sends outputs to the multiboard PCB.
