Dynamic System; Lighting System; Underwater Drone Functions - Aquarobotman NEMO User Manual

Dynamic System

The dynamic system of the drone is mainly formed by a 4-duct propeller system which is composed of 2
horizontal + 2 vertical propellers, provides the drone with power needed for underwater movements and
makes it flexible for various maneuvers of submerging, floating, moving forwards or backwards and
steering. The propeller consists of motor and propeller blades. With anti-corrosive motors of customized
professional waterproof and self- designed propeller blades, the performance of the motor is increased to
its maximum potential.

Lighting System

The underwater drone adopts adjustable matrix low beam fill lights with a maximum brightness of 1000lm
to ensure high-quality pictures taken in a dim environment.
Suggestions: in the case of noon, sunny day or other scenarios when there is adequate illumination, the
light can be turned off to save battery. At night or in caves and deep waters where the illumination is weak,
the fill light should be turned on.

Underwater drone Functions

1. Depth Hold: under normal circumstances, the drone can be controlled and move in horizontal direction
with its current depth and pitch angle unchanged.
Notes: this function relies on the drone's internal sensors. In some complex scenarios, such as when
there is strong magnetic field interference, the drone will be unable to operate regularly. In such
situations please leave the area to a safe place to use it.
2. Direction Hold: under normal circumstances, the drone can be controlled to submerge or float through
snorkeling throttle controller with its current fuselage direction unchanged.
3. The omnidirectional operation: this mode supports a multiple control mode and enables complex
maneuvers such as tilting upwards or downwards at large angles. This mode restricts the tilt angle of to
±45° and the speed of tilting is different under different speed level.
4. VR somatosensory operation: VR somatosensory control is supported, users can change the
perspective of the drone through head movements for immersive experience.
5. Smart Protection System: The built-in protection system can trigger corresponding protection for the
drone in case of unexpected abnormal situations during usage, to protect the drone from damage. The
service life of the drone shall be greatly extended.
1) Temperature protection: the normal operating temperature of the drone is -2°C-35°C. If the drone
detects an abnormal internal temperature, it will enter a protective state.
Two main reasons for abnormality:
a) Operating in high temperature waters.
b) The drone was turned on and exposed in the air for long time, and the internal temperature of
the drone got too high.
2) Humidity protection: when the drone detects too much humidity, it will take protective measures.
