3D Robotics Aero

- M
Design and Operational Characteristics According to 3D Robotics, the Aero

- M is an all

- in

- one solution for creating high

resolution visual

- spectrum aerial maps. The fixed

- wing platform offers incredible

en durance and scope of coverage, with 40 minutes of flight time and up to 250 acres of coverage area. It’s the perfect platform for regularly acquiring highly detailed and actionable data for large

- scale operations such as farming, construction and conservat ion, as well as search and rescue and emergency response. The Aero

- M has a lightweight and robust foam frame, which translates to less risk and cost per flight and multiplies the cost

effectiveness of our platform.

The 3D Robotics Aero

- M is used with the P ixhawk Flight Control Station. Pixhawk is an advanced autopilot system designed by the PX4 open

- hardware project and manufactured by 3D Robotics. It features advanced processor and sensor technology

from ST Microelectronics® and a NuttX real

- time operating system, delivering incredible performance, flexibility, and reliability for controlling any autonomous vehicle.

The Pixhawk system includes integrated multithreading, a Unix/Linux

- like programming environment, completely new autopilot functions such as Lu a scripting of missions and flight behavior, and a custom PX4 driver layer ensuring tight timing across all processes. Pixhawk allows existing APM and PX4 operators to seamlessly transition to this system and lowers the barriers to entry for new users to p articipate in the exciting

world of autonomous vehicles.

Operating Procedures

In terms of operating proce dures, the below preflight inspection steps are strongly suggested to ensure safe flight operations of the 3D Robotics Aero

- M sUAS as described in Appendix A :

Before each flight, perform a physical component check, center of gravity check, and control chec ks in both manual and stabilize modes. If any of the components or assemblies in these checks are not secure, tighten the screws or use CA glue (super glue) to secure the components to the foam.

1) Examine the Aero to ensure that all components are secured i n flight configuration.

a. Check that the wings, tail, and tail boom are fully assembled and securely attached.

b. Check that the propeller is secured tightly to the motor.

c. Check that the servo rods are secured to the servo horns with the blue clasps.

2) Check tha t the airspeed sensor is secured to the side of the Aero and the tube

is free from obstructions.

3) With the battery connected and the lid secured, check that the Aero is correctly balanced for flight. Hold the Aero with one finger on each of the clear, plas tic balancing points shown below. These points indicate the Aero’s center of gravity.

4) If the plane balances on your fingers, then the center of gravity is correct. If it won’t balance, adjust the position of the battery until you can balance the plane on two fingers. Flying the plane without the camera will affect the center of gravity. If you choose to fly without the camera, make sure to re

balance the center of gravity.7 | P a g e

Radio Frequency

The 3D Robotics Aero

- M will be operated on a 2.4 ghz frequency.

N OTE: FCC license is not required to utilize the above frequency.

Lost Link / Fail Safe

The Aero

- M is programmed with a set of failsafe behaviors to prevent a crash in the event of a loss of one of the data or communication channels required

for auton omous flight. In the event of a loss of GPS or lost

- link, the assigned pre

coordinated behavior will activate. To override the failsafe behavior, sometimes referred to as return to launch (RTL); use the controller to regain manual control.

The below fail safe m odes are described in Appendix A :

Regaining Manual Control

To regain manual control during the mission, switch to fly

- by

- wire mode using the controller. If you’re a confident operator, switch to stabilize mode. If you observe instability in the Aer o’s flight behavior or it the aircraft moves outside your designated safe flying area, switch to RTL. Turning off the controller will automatically trigger an RTL and can be used in an emergency situation as a hard recall command.

RC Controller Signal F ailsafe

Physical obstructions and interference from nearby wireless signals
can affect the Aero’s connection with the RC controller.

If the Aero loses contact with the controller, it will return to the launch point automatically and enter into a circle pat tern above the launch point, indicated by a blinking yellow status LED.

If the controller failsafe is triggered, wait for the Aero to return to the launch point, then regain manual control and either land or restart the

mission.

Low Battery Failsafe

Envir onmental conditions can affect power consumption. Use the Mission Planner Flight Data display to monitor the voltage of the battery during flight.

If the battery reaches 13.8 V, the Aero will return automatically to circle above the launch point, indicated by a blinking yellow status LED and a qui ck repeating tone8 | P a g e

3D Robotics X8

Design and Operational Characteristics

According to 3D Robotics, the X8

- M is easy to fly and simple to operate. The X8

- M can take off and land even in the tightest areas, which makes the vehicle compatible with just about any type of terrain. And because the X8

- M can fly at low altitudes and at slow speeds, it can capture images with a level of detail and precision that’s impossible to acquire with manned flights or satellite ima gery.

The X8

- M package includes a Canon S100 high

- resolution 12 MP camera and the powerful image processing tool, Pix4Dmapper Mosaic 3DR Edition, to create highly accurate, georeferenced and orthorectified mosaics. Pix4Dmapper Mosaic 3DR Edition works spe cifically with the X8

- M imaging system only. The X8

- M ships in a custom

designed hard

- top travel case to keep all the components of the mapping system protected and easily accessible, ensuring that you're always ready to map. X8

Operating Procedures

In terms of operating procedures, the below preflight checks are str ongly suggested to ensure safe flight oper ations of the 3D Robotics X8

- M sUAS as described in Appendix B :

Visual Check

Before flying, examine the X8 to verify the following:

1) All propellers are tightly attached in the correct order with the writing

on each propeller facing the sky.

2) All propeller s can spin without obstruction.

3) The antenna is oriented vertically.

Test Flight

Before flying the mission, fly a brief tes t flight to verify that the X8:

1) Responds to controls correctly in stabilize mode.

2) Holds posi tion in loiter mode.

3) Correctly execut es a return

- to

- launch command

Radio Frequency

The 3D Robotics X8

- M will be op erated on a 2.4 ghz frequency. NOTE: FCC license is not required to utilize the above frequency.10 | P a g e

Lost Link / Fail Safe

The X8 is program med with a set of failsafe behaviors to prevent a crash in the event of a loss of one of the data or communication channels required for autonomous flight. Although certain failsafes have assigned LED indicators and tones, it is unlikely that you will be a ble to see these at a distance. Monitor the Flight Data screen for failsafe indications. If a failsafe is triggered, the assigned behavior will activate. To override the failsafe behavior (RTL in most cases), use the controller to regain manual control.

Regaining Manual Control

To regain manual control during the mission, switch to fly

- by

- wire mode using the controller. If you’re a confident operator, switch to stabilize mode. If you observe instability in the Aero’s flight behavior or it

the aircraft mov es outside your designated safe flying area, switch to RTL. Turning off the controller will automatically trigger an RTL and can be used in an emergency situation as a hard recall command.

Ground Station Signal Failsafe

Physical obstructions and interfer ence from nearby wireless signals can affect the X8’s connection with the ground station. Use the Mission Planner Flight Data display to monitor the ground station connection strength during flight. If the X8 loses contact with the ground station for

over five seconds, it will automatically return to the launch point and land.

RC Controller Signal Failsafe

Physical obstructions and interference from nearby wireless signals
can affect the X8’s connection with the RC controller. If the X8 loses
contact wi th the RC controller, it will return to the launch point automatically and land, indicated by a blinking yellow status LED.

Low Battery Failsafe

Environmental conditions can affect power consumption. Use the Mission Planner Flight Data display to monitor the voltage of the battery during flight. If the battery reaches 14 V, the X8 will land automatically at the current position, indicated by a blinking yellow status LED and a quick repeating tone.

GPS Failsafe

Enclosed areas, physical obstructions, and lack of available satellites can affect GPS strength. Use the Mission Planner Flight Data11 | P a g e display to monitor the GPS during flight. If the X8 loses GPS lock for over five seconds, it will land automatically at the current position.

Altitude Failsafe

The X 8 has a 120 m altitude geofence enabled by default. If the geofence is breached, the X8 will automatically RTL.

Operating Procedures

In terms of operating procedures, the below preflight checks are strongly suggested to ensure safe flight oper ations of the 3D Robotics Iris Plus sUAS as

described i n Appendix C :

Select an open area for flying, away from people and buildings, and remember to bring the Flight Checklist and a fully charged battery. Determine the boundaries of your flying area before takeoff, and select a level, unobstructed

space as a launc h point. Follow these preflight and postflight steps in the order
shown h ere and on the Flight Checklist every time you fly.

1) Check Iris

 Point the controller antenna up and the IRIS antenna down for the strongest signal.

 Set the mode switch to stan dard (STD). If you’re new to flying, try starting your first flight in loiter (LTR)
instead of standard.

 Ensure that the RTL switch is set to OFF.

2) Power on Controller

 Ensure that the controller is always turned on while IRIS is powered.
If IRIS loses c ommunication with the controller in flight, IRIS will
initiate an automatic return to launch.

 Press and hold the DN button on the controller to view flight data from IRIS. See the Flight Checklist for more information about controller flight data.

3) Connec t Battery

 Press the sides of the battery compartment together and rotate the door
down.13 | P a g e  Insert battery, and attach the yellow connectors. To close, squeeze the door, and rotate up until it clicks into place, ensuring that the battery
cables do not interfe re with the LED cables.

 Place IRIS at the launch point with the black arms facing towards you and the blue arms facing away from you.

 Connect the radio to your ground station, and select Connect.

4) Press Safety Button

 Press the safety button until it is solid red. IRIS is now live.

Stand back!

5) Check LED

 Check the LED to view the status of IRIS. Wait to proceed until you see the blinking green light indicating that IRIS has acquired GPS
lock.

Radio Frequency

The 3D Robotics Iris Plus will be operated on a 2.4 ghz frequency. NOTE: FCC license is not required to utilize the above frequency.

Lost Link / Fail Safe

Environmental factors, such as wind and GPS irregularities, can cause instability in flight. IRIS will attempt to compensate for these facto rs by triggering a failsafe if it detects an unsafe flying condition due to loss of controller signal, loss of GPS signal, or low battery (see below for details). To avoid potential hazards due to environmental factors, identify the boundaries of your flyi ng area before takeoff, and recover IRIS manually by switching into standard (STD) if it moves outside your designated flying area.

Loss of RC signal

Always use the controller as a primary or backup control system when flying. Ensure that the controller is turned on any time IRIS is powered. If contact with the controller is lost during flight, IRIS will land and display a blinking yellow LED. If IRIS is more than 2 meters (6.5 feet) from the launch point, it will return to launch (RTL) before landing. ( See page 13 for more information about RTL.)

Loss of GPS signal

IRIS requires an active GPS signal before takeoff. If IRIS loses GPS signal in flight, it will trigger a GPS failsafe, indicated by a blinking blue and14 | P a g e yellow LED with a high

- high

- high

- low t one, and automatically switch to manual control (standard

- altitude hold mode). Always be prepared to regain manual control of IRIS at any time while flying and choose an unobstructed flying area to improve GPS signal strength. When flying a mission, we r ecommended changing the GPS failsafe behavior to land. (Visit 3dr.com/iris/info for more information about configuring the GPS failsafe.)

Low battery

When the battery reaches 25% of its remaining charge, IRIS will land and display a blinking yellow LED w ith a quick repeating tone. If IRIS reaches the low battery limit during a mission, it will return to the launch point before landing.

It is user friendly, safe, stabilized and easy to fly while its integrated design makes assembly and configuration simple and fast. Retractable landing gear,20 | P a g e

vibration dampers, slightly angled arms and a minimalized gimbal mount allow for a clear 360 degree view from the camera. A patented power distribution board, built in high

- speed ESC’s and motors with high efficiency propellers ensure dynamic stability and maximized power efficiency. Used with the DJI A2 Flight Control System Use r Manual Version 1.2 , attached as Appendix G , the S900 can hover and fly reliably making it ideal for photography and cinematography.

Please refer to the attached appendices for additional detailed information pertaining to these sections which is consis tent with the instructions found on page five of the FAA document titled, “Pubic Guidance for Petitioners for Exemption Filed under

Section 333.”

1. Safe and stable

(1) The S900’s V

- type mixer design provides large amounts of propulsion while improving power efficiency. Combined with DJI flight controllers like the A2, it is guaranteed to remain stable even with the loss of a rotor.

(2) A more reliable, safe, and simplified power wiring system is easy to setup, and eliminates the need for soldering. Th e main power cord uses an AS150 spark

proof plug and an XT150 plug, preventing creators from mixing up polarity when plugging in the battery, and also helping prevent short circuits.

(3) All frame arms and the retractable landing gear are made from carbon fiber, ensuring lightweight and high structural stability.

2. Professional hexacopter

(1) Weighing approximately 3.3kg with a maximum takeoff weight of about 8.2kg, the S900 can easily carry equipment such as the Zenmuse gimbal systems

and a set of shootin g equipment. Used with a 6S 16000mAh battery it can fly for up to 18 minutes.

(2) The gimbal is mounted low on the frame on a specifically designed bracket. When combined with our retractable landing gear, we have a very wide range of possible shooting ang les.

(3) The gimbal and battery are mounted to the same bracket, with dampers placed between the bracket and the frame. This significantly reduces high

- frequency vibrations and makes shots clearer and sharper. The battery tray's position also

makes it more stable and convenient for mounting and dismounting.

3. Portable and easy to use

(1) All six arms can be folded down, and the 1552 folding propellers can be tucked away, minimizing the S900’s size during transport.21 | P a g e (2) To fly, simply lift the frame arms up , lock them in place with the red clips, and power up the system. This greatly saves on pre

- flight prep time and you can be ready to fly in less than 5 minutes.

(3) The upper center plate can be removed quickly, making it convenient and efficient to arrang e or change the power system, control system, and other

accessories.

4. Easy to control and fly

(1) Each frame arm is designed with an 8° inversion and a 3° inclination, making the aircraft more stable when rolling and pitching, and more flexible when

rot ating.

(2) Each frame arm has a built

- in 40A electronic speed controller (ESC). When combined with the 4114 pro motor and high performance 1552 folding propellers, the S900 is capable of a maximum thrust of 2.5Kg.

Lost Link / Fail Safe

The DJI S900 A2 failsafe works when the transmitter signal is lost, the flight control system will automatically control the aircraft to reduce injuries or damag e.

Home point is recorded prior to flight. If the S900 loses signal with the transmitter, it will reference home point to return to take off position

. If the S900 is below a predetermined altitude which is based on specific environment conditions, the S 900 will climb to that predetermined altitude and hover. After hovering at that altitude for ten seconds, it will then fly to the pre

- set home point and hover for 10 seconds. After the S900 hovers for ten seconds over the pre

- set home point, it will desc end and land at the home point. After it lands, the S900

will shut off.

Please refer to Appendix G , page three, steps one through six for a more detailed description of the failsafe modes and procedures when signal is lost.

RTD X5 Fixed Wing

Design a nd Operational Characteristics

The RTD X5 is an all

- in

- one solution for creating high

- resolution visual

spectrum and/or Near Infrared (NIR) spectrum aerial maps. The swept fixed

- wing platform offers incredible endurance given its small form factor and li ght weight. With an average flight duration of 50 minutes and up to 300 acres of coverage area, it’s the perfect platform for regularly acquiring highly detailed and actionable spatial data. Some disciplines that can benefit from the RTD X5 capabilities in clude large

- scale operations such as farming, construction and conservation, as well as search and rescue and emergency response. The RTD X5 has a lightweight (2.46 lbs including battery and mapping camera) and robust foam frame, which translates to low ri sk and cost per flight and multiplies the

cost

- effectiveness of our platform.

The RTD X5 is controlled by the APM or Pixhawk Flight Control System running Arduplane firmware. APM and PixHawk are advanced autopilot system designed by 3D Robotics and the PX4 open

- hardware project and manufactured by 3D Robotics. Both flight controllers offer incredible performance, flexibility, and reliability for controlling any autonomous vehicle. The PixHawk provides the ability to store data on an micro SD card allowing a dditional mapping capabilities such as Raw GPS data capture for advanced Real Time Kinematics (RTK) post processing.

Operating Procedures

In terms of operating procedures, the below preflight inspection steps are strongly suggested to ensure safe flight operations of the RTD X5 sUAS

. Additionally , refer to Appendix H for detailed information on operating and
maintenance procedures :

Before each flight, perform a physical component check, center of gravity check, and control checks in both manual and stabilize modes. If any of the components or assemblies in these checks are not secure, tighten the screws or use CA glue (super glue) to secure the components to the foam.

1) Examine the X5 to ensure that all components are secured in flight con figuration.

a. Check that the main battery and camera are securely mounted
b. Check that the propeller is secured tightly to the motor.

c. Check that the servo rods are secured to the servo horns with the compression fasteners.25 | P a g e 2) With the battery connected and the lid secured, check that the X5 is correctly balanced for flight. Hold the X5 with one finger on each of the foam balancing points below wings. These points indicate the X5’s center of gravity.

3) If the plane balances on your fingers, then the center of grav ity is correct. If it won’t balance, adjust the position of the battery so that it is properly seated in the
forward

- most position. Flying the plane without the camera will affect the center of gravity. If you choose to fly without the camera, make sure to re

- balance the center of gravity.

Radio Frequency

The RTD X5 will be operated on a 2.4 ghz frequency. NOTE: FCC license is not required to utilize the above frequency.

Lost Link / Fail Safe

The RTD X5 is programmed with a set of failsafe be haviors to prevent a crash in the event of a loss of one of the data or communication channels required for autonomous flight. In the event of a loss of telemetry or or R link, the assigned pre

- coordinated behavior will activate. To override the failsafe behavior, sometimes referred to as return to launch (RTL); use the controller to regain
manual control. The below failsafe m odes are described in Appendix H :

Regaining Manual Control

To regain manual control during the mission, switch to fly

- by

- wire
mod e using the controller. If you’re a confident operator, switch to stabilize mode. If you observe instability in the X5’s flight behavior or if the aircraft moves outside your designated safe flying area, switch to RTL. Turning off the controller will autom atically trigger an RTL and can be used in an emergency situation as a hard recall command.

RC Controller Signal Failsafe

Physical obstructions and interference from nearby wireless signals
can affect the X5’s connection with the RC controller.

If the X5 loses contact with the controller, it will return to the launch point automatically and enter into a circle pattern above the launch point.26 | P a g e If the controller failsafe is triggered, wait for the X5 to return to the launch point, then regain manual control and either land or restart the
mission.

Low Battery Failsafe

Environmental conditions can affect power consumption. Use the Mission Planner Flight Data display to monitor the voltage of the battery during flight.

If the battery reaches 10.3 V, the X5 will return automatically to circle above the launch point or a programmed “rally point”. If RC control cannot be regained and/or telemetry connectivity is lost, the X5 will reach a low Voltage cutoff of the integrated Battery Eliminator Circuit (BEC), a t whic h point the motor power will be cut. The X5 will retain full flight control and continue to glide in a circular pattern around the rally or
launch location until it lands.
