Introduction

The Agras MG-1 (abbreviated as MG-1) is a battery-powered multirotor aircraft designed for

agricultural applications in variety of environments and terrains, including terraces, elds, forests and orchards. It is dust-proof, water-proof (IP43 protection rating, IEC standard 60529) and made

of anti-corrosive materials, allowing it to be rinsed clean.

The MG-1 also includes DJI’s industry-leading flight control system and three useful Operation Modes: Smart, Manual and Manual Plus. A microwave radar underneath the aircraft makes the MG-1 uniquely versatile across different terrains and the combined Altitude Stabilization System automatically maintains the aircraft’s height above plants to ensure optimal spraying.

The remote controller features a Spraying Status Panel decorated with intuitive icons and a range of

controls for navigation, mode and spraying. While the MG-1 does all the hard work in the elds, you

keep full control over it in the palm of your hands.

Feature Highlights

The MG-1 provides three useful Operation Modes: Smart, Manual and Manual Plus. In Smart Operation Mode, the aircraft will travel along a pre-planned route and spray liquid payload.

Users can set the operation gap, ying speed and other parameters. The MG-1 can cover an area of 7-10

acres per hour. In Manual Operation Mode, users can start and stop spraying manually and also adjust the spray rate. In Manual Plus Operation Mode, the flying speed is restricted and the aircraft’s heading is locked. Except for the heading, users can control the movement of the aircraft.

The MG-1 also includes two intelligent memory features: operation resumption and system data protection. When the operation mode is changed from Smart Operation Mode, operation resumption records a set point for the aircraft to return to when Smart Operation Mode is reinstated. System data protection keeps the system data for a period of time even when powered off so users can resume their missions after replacing the battery.

The spraying system includes a spray tank, sprinklers and other accessories. The four sprinklers placed on the aircraft’s two sides provide well-distributed spraying and great coverage. The nozzles on the Agras MG-1 can also be swapped out to meet the needs of different applications.

The MG-1 provides Smart Operation Mode, Manual Operation Mode and Manual Plus Operation Mode. The Altitude Stabilization System included with the MG-1 keeps a constant height above crops in Smart Operation Mode and Manual Plus Operation Mode. Functions such as operation resumption, system data protection, empty tank warning, Return-to-Home (RTH) and low battery level warning are also available.

When using your MG-1 for the rst time, you will need to activate it in the MG-1 Assistant.

Refer to MG-1 Assistant (p. 34) for details.

Effective use of pesticides relies on pesticide density, spray rate, spray distance, aircraft

speed, wind speed and wind direction. Consider all factors when using pesticides.

Always y at an appropriate height above crops to avoid damage.

Operation Mode

The MG-1 provides Smart Operation Mode, Manual Operation Mode and Manual Plus Operation Mode. Switch to one of the three modes via the Operation Mode Switch on the remote controller. In Smart Operation Mode, the aircraft will travel along a pre-planned route and spray liquid payload. In Manual Operation Mode, users can start and stop spraying manually and also adjust the spray rate.

In Manual Plus Operation Mode, the ying speed is restricted and the aircraft’s heading is locked.

Except for the heading, users can control the movement of the aircraft.

Smart Operation Mode

In Smart Operation Mode, the aircraft will travel along a pre-planned route. Operation resumption, data protection, and altitude stabilization system are available in this mode. Use the Flying Speed

Dial on the remote controller to adjust ying speed, spray rates will automatically adjust accordingly.

Smart Operation Mode is recommended for large, rectangular spray areas.

Operation Route

The aircraft will travel along pre-designated square zig zag route after the turning points A and B have been recorded. The altitude difference between the aircraft and vegetation is maintained under

optimal working conditions. The aircraft will spray liquid automatically while ying along the route

and stop spraying liquid while hovering at the turning points. The length of the dotted lines, which are called Operation Gaps, can be adjusted in the MG-1 Assistant.

Manual Operation Mode (refer to Controlling the Spraying System on p. 18 for details) and then return to Smart Operation Mode after setting a new rate.

Altitude Stabilization System

Profile

To ensure that the spray is evenly dispensed, the aircraft uses the radar module on the Altitude Stabilization System to maintain the same distance above the crops at all times. The radar module is

enabled by default, and can be disabled in MG-1 Assistant. If it is enabled, the aircraft will y above

the crops at a constant spraying distance in Smart Operation Mode and Manual Plus Operation Mode. The system can also measure the spraying distance above the crops or other surfaces, but

the aircraft will not be able to y at a constant spraying distance when performing this function.

How to Use

1. Ensure that the Operation Mode Switch is toggled to the Manual Operation Mode. Fly the aircraft above the vegetation and adjust the spraying distance between the aircraft and the vegetation. DO

NOT operate the aircraft above vegetation beyond the detection range (1.5 - 7 m) while adjusting

aircraft altitude, otherwise the Spraying Status Panel will not be able to display the current spraying distance.

2. Conrm the desired spraying distance by observing the Height LEDs on the Spraying Status Panel. Ideal spraying distance should fall within the working range (2 - 3.5 m) for altitude

stabilization. DO NOT operate the aircraft beyond this range, otherwise the system will become unstable.

Page 31

AGRAS MG-1 User Manual

3. Toggle the Operation Mode Switch to enter Smart Operation Mode or Manual Plus Operation

Mode. If operating environment is ideal, the aircraft will y above the vegetation at the pre-set

height.

The Altitude Stabilization System will only maintain a xed distance from vegetation within

its working range (2-3.5 m).

The aircraft’s pitch and roll angles must not exceed 20°. Observe the aircraft’s distance from the vegetation at all times. Operate with extra caution in any of the following situations:

a. There are large height differences (> 1m) in vegetation (i.e. nearby ditches or ponds,

above sparse trees or shrubs, terraced elds).

b. Flying at high speeds (> 5m/s).

c. Flying over surfaces that can absorb sound waves (e.g. dense vegetation comprised

of small leaves such as well-maintained grass lawns).

d. Flying over inclined surfaces (depending on aircraft speed). Recommended maximum

inclination at different speeds: 15° at 1 m/s, 6° at 3 m/s and 3° at 5 m/s.

Obey local radio transmission laws and regulations.

Return-to-Home (RTH)

RTH: The Return-to-Home (RTH) function brings the aircraft back to the last recorded Home

Point.

Home Point: If the GPS signal is strong enough (GPS count ≥ 6) after powering on for 30 seconds, then the launching location of the aircraft will be recorded as the Home Point.

When using System Data Protection, the Home Point will not be updated if you restart the

aircraft after changing the battery.

There are two events that will trigger RTH procedure: Smart RTH and Failsafe RTH.

Smart RTH

Use the RTH button on the remote controller (see RTH Button on p. 21 for more details) when GPS is available to enable Smart RTH. Press and hold the RTH button to enable Smart RTH. The same RTH procedure is applied to both Smart RTH and Failsafe RTH. With Smart RTH, you may control the aircraft’s orientation to avoid collisions when it is returning to the Home Point. To exit Smart RTH, regain control manually. Refer to How to Regain Control (p. 33) for more details.

It is not possible to start the RTH procedure by pressing the RTH button when the Flight

Mode is toggled to the “M” position.

Failsafe RTH

The Failsafe RTH must be enabled in the MG-1 Assistant. If Failsafe RTH is not enabled, the aircraft will hover in place when the remote controller signal is lost.

Failsafe RTH is activated automatically if the remote controller signal is lost for more than 3 seconds provided that the Home Point has been successfully recorded and the compass is working normally. The operator can interrupt the Return-to-Home procedure and regain control over the aircraft if the remote

controller signal is recovered. Refer to How to Regain Control (p. 33) for details.

Calibrating the Compass

The compass is built in the landing gear. Be sure to calibrate the compass before your rst ight,

or else the aircraft cannot work properly. The compass is a very sensitive instrument that requires regular calibration to ensure optimal flight performance. Abnormal compass data due to a lack

of calibration can lead to poor ight performance or even failure. Regular calibration enables the

compass to keep optimal performance.

DO NOT calibrate your compass where there is a chance of strong magnetic interference,

such as magnetite quarries, parking structures, and underground steel reinforcements. DO NOT carry ferromagnetic objects such as cellular phones with you during calibration. DO NOT calibrate besides massive metal objects. DO NOT calibrate in an indoor space.

Calibration Procedures

Choose an open space to carry out the following procedures. It is recommended to calibrate the compass with an empty tank.

1. Flip the Flight Mode Switch back-and-forth at least 6 times, until the Aircraft Status Indicator becomes solid blue.

2. Hold the aircraft upright and rotate it 360 degrees along the central axis, until the Aircraft Status Indicator changes from solid blue to solid green.

3. Hold the aircraft with its nose facing up and rotate 360 degrees along the central axis.

P- mode M- mode

4. The Aircraft Status Indicator shows the current flight mode when calibration is complete. If the Aircraft Status Indicator becomes blinking red, repeat the steps above to recalibrate the compass.

When to Recalibrate

1. The compass data is abnormal, and the Aircraft Status Indicator is blinking red and yellow alternatively.

2. Flying in a new location, or a location that is different from your last ight.

3. The mechanical structure of the MG-1 is changed.

4. Severe drifting occurs in ight, i.e. the MG-1 has difculty ying in a straight line.

Starting and Stopping the Motors

Starting the Motors

The Combination Stick Command (CSC) listed below is used to start/stop the motors. Ensure you

perform the CSC in one continuous motion. The motors will begin to speed at an idle speed. Take off immediately after the motors are spinning, or else the aircraft may lose balance, drift or even takeoff by itself and injure nearby people.

CSC 1 CSC 2 CSC 3 CSC 4

Stopping the Motors

There are two methods to stop the motors.

1. When the aircraft has landed, push the throttle stick down, then perform the CSC command to stop the motors. Release both sticks once the motors have stopped.

Throttle Stick

2. When the aircraft has landed, push the throttle down and hold. The motors will stop after 3 seconds. (In M-mode, when “M” is set as Manual mode in the MG-1 Assistant, use method 1 to stop the motors.)

Throttle Stick

Flight Test

1. Place the aircraft near the operation area with the Aircraft Status Indicator facing you.

2. Power on the remote controller. Connect the battery to the communication port and then the

XT90 port.

3. Toggle the Operation Mode Switch to Manual Operation Mode.

4. Toggle the Flight Mode Switch to P-mode. Wait until there is no red blinking from the Aircraft Status Indicator, which means the GPS signal is strong. Then perform CSC command to start the motors.

5. Push the throttle stick up to take off.

6. Select the desired Operation Mode and spray liquid.

7. To land, ensure the Operation Mode Switch is toggled to Manual Operation Mode and hover over

a level surface and gently pull down on the throttle stick to descend slowly.

Page 44

AGRAS MG-1 User Manual

8. After landing, perform the CSC command to stop the motors.

9. Disconnect the battery from the XT90 port and then the communication port. Then power off the

remote controller.

When the Aircraft Status Indicator blinks blue during flight, the aircraft has entered

Failsafe mode.

The low battery level warning is triggered when the Aircraft Status Indicator blinks yellow.

Fly the aircraft back and land it as soon as possible, then stop the motors and replace the battery.

The critically low battery level warning is triggered when the Aircraft Status Indicator

blinks red. The aircraft will begin to descend and land automatically. You can change the

settings in MG-1 Assistant so that the aircraft does not automatically descend and land when the Aircraft Status Indicator LED blinks red.
