Product Introduction
This chapter mainly introduces the features and functions of Nemo.
Brief Introduction
The underwater drone Nemo with 4K UHD shooting system and four-ducted stability system enable
real-time, stable and high-definition shooting underwater. The maximum underway speed in water is 2m/s
and duration of running underwater reaches 3 hours. At the same time, the modular design makes the
product more convenient to carry and longer battery life.
Function Features
1. High-definition 4K lens. Support 4K video capture and shooting with 16 million pixels. 120/fps video
capture with the QAS-Balance system enables high-quality dynamic images to be snapshotted.
2. QAS-Balance system. The four-ducted structure design and the independently developed control system
enable Nemo to run stably underwater and perform stable video and photo capture.
3. Detachable battery design. The hosting machine battery is detachable, which finishes loading and
unloading steps through the rotary knob. If the battery is run out, another battery can be replaced. At the
same time, the battery of wheel on wireless transmitter is also independently replaceable.
4. Dynamic experience. Provide various operating methods such as mobile APP, handle, and VR glasses. The
APP control interface is simple and quick to get started. In VR mode, the handle works on control when it is
operated with VR glasses at the same time. The somatosensory control mode is set, which makes the
machine movement is synchronized with the head movement, bringing more real feeling to the user.
Module Composition
Mainly introduce the various modules of the whole machine, detailed parameters can be viewed in the
appendix specification parameter table.

Power System
The power system is mainly composed of two horizontal + two vertical four-ducted thrusters. The thruster
is composed of a customized waterproof and corrosion-resistant motor. With the self-designed propeller,
the performance of the motor can be improved to the highest.
Lighting System
Adjustable matrix lower beam fill light with a maximum brightness of 1000lm.
Suggestions: It is recommended to turn off the fill light to save power in the day time. The fill light needs to
be turned on in water holes with weak light at night.
Hosting Machine Function
1. Depth-oriented: When controlling the horizontal direction, the machine maintains the current depth and
pitch angle unchanged. This mode relies on the internal sensors of the machine. If complicated situations
happen, such as strong magnetic field interference, the machine will not operate normally. Please head to
safe place.
2. Direction-oriented: The direction of the machine remains unchanged, and the snorkeling throttle
controls the machine to float or dive.
3. Open-ended operation: This mode provides a fully open control mode to complete complex dive
postures, such as the machine moving up or down at a large angle. In this mode, the machine's pitch angle
is limited to ±90°, and the pitch angle can be controlled according to different speed levels.
4. VR somatosensory operation: This operation needs to be used with VR glasses. In VR mode, it has a
somatosensory start lock. The user needs to lift the head up more than 60°, then lower the head more than
60°, finally return the head back and thus the somatosensory function can be unlocked. After unlocking,
the machine angle can be controlled by the head posture.
Smart Protection System
The machine will react to unexpected situations:
1. Temperature protection: The normal working water temperature of the machine is -2 °C-35 °C. If the
internal temperature of the machine is abnormal, it will start protection mode.
There are two situations:
a) Work in water with high temperature.
b) The machine is kept in the air after power on, and the internal temperature of the machine is too high.
2. Humidity protection: The protective measures are activated when the machine is too humid. This
problem does not occur in normal use and needs to be returned to the factory for repair when problems
occur.
3. Overcurrent protection: The main causes are as follows:
a) The propeller is entangled and cannot be rotated.
b) Internal performance failure results in short circuit.

4. Low voltage protection: This protection will be triggered when the battery voltage is too low. When the
voltage is lower than 10%, the APP will occur page reminder; when the voltage drops to 0%, the battery will
automatically power off. At this point, the machine can only be manually pulled out of the water through
the KAVLAR signal cable.
5. Motor protection: When the machine's pitch angle or roll angle is greater than 60°under unlocking and
without any control, the motor stops rotating and enters protection mode until the pitch angle and roll
angle are less than 60° at the same time.
Smart Battery
The hosting machine battery acts as a separate part with a built-in intelligent control panel to ensure the
safety of the battery as a connection to various states. The specific features are as follows:
1. Load detection: When it is not loaded, the battery is in sleep state and will not discharge. It only works
when the battery is connected to the machine.
2. Battery self-test: After the battery is installed on the hosting machine, it will first perform a self-test to
check whether the power meets the requirements to power on.
3. Battery short-circuit protection: When the battery detects a short circuit, it will cut off the output and
protect the battery.
4. Discharge overcurrent protection: During the discharge process, if the current is too large, the output will
be cut off to protect the battery and external circuits.
5. Battery storage: The battery can be placed in any state for a short period of time. If it needs long-term
placement, the battery will remain at 80%.

Wireless Transmitter
As a link of communication between the underwater drone and user terminals
Brief Introduction
The wireless transmitter has a built-in WIFI signal, and the battery of which is independently detachable.
The mobile terminal can be connected to WIFI by the Aquarobotman's APP to view the status of the
machine in real time. Please refer to the operation guide for specific operations. Users can choose a wheel
to achieve convenient cable recycling.
KEVLAR Tether Cable
The main function of the KEVLAR signal cable aims to transmit signals. The cable built-in reinforced KEVLAR
fiber can withstand a maximum tensile force of 100kg. It exhibits neutral buoyancy in fresh water, and slight
buoyance in seawater.
WIFI Signal
The WIFI signal uses the 802.11a standard, and the communication distance in a spacious place reaches
50m.
Protection System
When the battery voltage is too low, the system will automatically power off to protect the wireless
transmitter battery.
