In Nature Robotics Ltd. www.innaturerobotics.com Introduction The AMOS-AirProp is an electric, computer controlled, rotatable air propeller that is used for propulsion and steering of the AMOS (Aquatic Mini Observation System) robot from In Nature Robotics Ltd. It consists of a 10 inch propeller blade that is mounted to a 880 kv brushless motor, which is in turn mounted to a vertical post whose yaw direction is controlled by a waterproof servo motor.

In Nature Robotics Ltd. www.innaturerobotics.com The screw potentiometer on the +6.5 V source should not be adjusted from its factory position. If you suspect that it might have been turned by accident, you can check the output voltage of the board between OUT+ and OUT- using a voltage meter. The measured voltage between these locations should be +6.5 V.
In Nature Robotics Ltd. www.innaturerobotics.com Voltages less than +6.5 V will not allow the motor to produce as much torque. Voltages greater than +6.8 V could damage the motor. The yellow or white wire of the servo motor should be connected to a PWM output of the microcontroller. The red wire is connected to the +6.8 V line and the black wire is connected to GND.
