Product Profile

Introduction

The Matrice 210/Matrice 210 RTK (M210/M210 RTK) is a powerful aerial imaging system with classleading agility and speed, redundant components for maximum reliability, and new smart features that make performing complex tasks easy. Gimbal cameras can be easily exchanged to suit your application's needs. Dual frequency remote controller transmission makes HD video downlink more stable and efficient. Upgraded With TapFlyTM and ActiveTrackTM flight modes, the aircraft can fly anywhere you tap on screen and track moving subjects effortlessly.

Feature Highlights

The aircraft’s mechanical design, along with quick-release landing gears and folding arms, makes it easy to transport, store, and prepare for flight. The drone’s new airframe design gives it an IP43

Ingress Protection Rating, in accordance with the global IEC 60529 standard.

Flight Controller: The flight controller has been updated to provide a safer, more reliable flight experience. A new flight recorder stores critical data from each flight. A system of visual sensors enhance hovering precision when flying indoors or in environments where GPS is unavailable. Dual

IMUs and barometers design provides redundancy.

HD Video Downlink: The low-latency long range (up to 4.3mi (7km)) HD downlink is powered by an enhanced­ version of DJI LIGHTBRIDGETM. Support of 2.4 GHz and 5.8 GHz ensures a more reliable connection­ in environments with more interference.

Camera and Gimbal: The camera unit is now independent from image processor so that you have the flexibility to choose the perfect gimbal and camera system (including ZENMUSETM X5S/X4S/XT*, and Z30) for each of your application. This means that regardless of which camera you choose, you have the same powerful processing backing it. The M210/M210 RTK can support a single upward gimbal or dual downward gimbals.* It is equipped with many expansion ports to broaden its applications. The M210 RTK has a built-in DJI D-RTKTM, which provides more accurate heading data for positioning.

Intelligent Flight Battery: The Intelligent Flight Battery features upgraded battery cells and an advanced power management system. Without a payload, the M210 provides up to 27 minutes of flight with TB50-M200 batteries and 38 minutes with high-capacity batteries (TB55). The M210 RTK offers up to 23-minute and 32-minute no-payload flight times with TB50-M200 and high-capacity batteries, respectively.

*The Zenmuse XT Gimbal Adapter is required when mounting the Zenmuse XT gimbal to the Matrice 200 series aircraft.

Both DJI GO 4 and DJI Pilot support the Zenmuse X5S, X4S, and Z30. DJI Pilot is required if using the Zenmuse XT. Gimbals can be purchased separately from the official DJI Online Store. A GPS module is required when using a single upward gimbal. DO NOT use an upward and downward gimbal simultaneously.

Aircraft

This section describes the features of the Flight Controller, Vision System, and the Intelligent Flight Battery.

Aircraft

Flight Controller

The M210/M210 RTK flight controller features several important upgrades. Safety modes include

Failsafe and Return-to-Home. These features ensure the safe return of your aircraft if control signal is lost. The flight controller can also save critical flight data from each flight to the on-board storage device. The new flight controller also provides increased stability and a new air braking feature.

Flight Mode

The following flight modes are available for the aircraft:

P-mode (Positioning) :

P-mode works best when the GPS signal is strong. The aircraft utilizes the GPS and Forward and Downward Vision Systems to locate itself, automatically stabilize, and navigate between obstacles. Intelligent Flight Modes such as TapFly and ActiveTrack are enabled in this mode.

When the Forward Vision System is enabled and lighting conditions are sufficient, the maximum flight attitude angle is 25°. When forward obstacle sensing is disabled, the maximum flight attitude angle is 30°.

When the GPS signal is weak and lighting conditions are too dark for the Forward and Downward Vision Systems, the aircraft will only use its barometer for positioning to control altitude.

Note: P-mode requires larger stick movements to achieve higher speeds.

S-mode (Sport):

The aircraft uses GPS for positioning. As Forward and Downward Vision Systems are disabled, the aircraft will not be able to sense and avoid obstacles when in Sport Mode. Ground Station and the Intelligent Flight functions are also not available in Sport Mode.

Note: Aircraft responses are optimized for agility and speed making it more responsive to stick movements.

A-mode (Attitude):

When neither the GPS nor the Vision Systems are available, the aircraft will only use its barometer for positioning to control the altitude. Ground Station and the Intelligent Flight functions are also not available in A-mode.

The Forward Vision System is disabled in S-mode (Sport), which means the aircraft will not be able to automatically avoid obstacles in its flight path. Be vigilant and stay clear of nearby obstacles.

The aircraft’s maximum speed and braking distance are significantly increased in S-mode

(Sport). A minimum braking distance of 164 feet (50 meters) is required in windless conditions.

The aircraft’s responsiveness is significantly increased in S-mode (Sport), which means a small stick movement on the remote controller will translate into a large travel distance of the aircraft.

Be vigilant and maintain adequate maneuvering space during flight.

The aircraft’s descent speed is significantly increased in S-mode (Sport). A minimum braking distance of 164 feet (50 meters) is required in windless conditions.

Use the Flight Mode switch on the remote controller to select aircraft flight modes.

Vision System and Infrared Sensing System

The main components of the Vision System are located on the front and bottom of the aircraft, including [1] [3] stereo vision sensors and [2] two ultrasonic sensors. The Vision System­ uses ultrasound and image data to help the aircraft maintain its current position, enabling precision hovering indoors or in environments where a GPS signal is not available. The Vision System constantly scans for obstacles, allowing the aircraft to avoid them by going over, going around, or hovering.

The Infrared Sensing System consists [4] of two infrared modules on top of the aircraft. These scan for obstacles on top side of the aircraft and is active in certain flight modes.

MATRICE 200 Series User Manual

Using Infrared Sensing System

The Infrared Sensing System can only be used to avoid large, diffuse, and reflective obstacles

(reflectivity >10%). Please be mindful of blind spots (Grey) of the Infrared Sensing System.

The performance of your Vision System and Infrared Sensing System is affected by the surface being flown over. Ultrasonic sensors may not be able to accurately measure distances when operating above sound-absorbing materials and the cameras may not function correctly in suboptimal environments. The aircraft will switch from P-mode to A-mode automatically if neither GPS nor Vision System and Infrared Sensing System are available. Operate the aircraft with great caution in the following situations.

The Vision System will be disabled when:

a)  Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green). b)  Flying over highly reflective surfaces.

c)  Flying over water or transparent surfaces. d)  Flying over moving surfaces or objects.

e)  Flying in an areas where the lighting changes frequently or drastically. f)  Flying over extremely dark (lux < 10) or bright (lux > 100,000) surfaces. g)  Flying over surfaces without clear patterns or texture.

h)  Flying over surfaces with identical repeating patterns or textures (e.g. tiling).

i)  Flying at high speeds of over 31 mph (50 kph) at 2 meters or over 11 mph (18 kph) at 1 meter.

The Ultrasonic sensors will be disabled when:

a)  Flying over surfaces that can absorb sound waves (e.g. thick carpet).

b)  Flying over inclined surfaces that will deflect sound waves away from the aircraft.

The Infrared be disabled when:

a)  Flying over obstacles with too small effective infrared reflective surface.

b)  DO NOT cover the protective glass of the infrared module. Keep it clean and undamaged.

20  © 2017 DJI All Rights Reserved.

MATRICE 200 Series User Manual

Keep sensors clean at all times. Dirt or other debris may adversely affect their effectiveness.

MATRICE 200 Series User Manual

Return-to-Home (RTH)

The Return-to-Home (RTH) function brings the aircraft back to the last recorded Home Point. There are three types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH. This section describes these three RTH types in detail.

GPS	Description

If a strong GPS signal was acquired before takeoff, the Home Point is the location from which the aircraft launched. The GPS signal strength is Home Point indicated by the GPS icon . Less than 4 bars is considered a weak GPS signal. The aircraft status indicator will blink rapidly when the home

point is recorded.

The aircraft can sense and avoid obstacles when the Forward Vision System is enabled and lighting conditions are sufficient. The aircraft will automatically ascend to avoid obstacles and descend slowly as it returns to the home point. To ensure the aircraft returns home while facing forward, it cannot rotate or fly left and right during RTH while the Forward Vision System is enabled.

Smart RTH

Use the RTH button on the remote controller or tap the RTH button in the DJI GO 4 app and follow the on-screen instructions when GPS is available to initiate Smart RTH. The aircraft will then automatically return to the last recorded Home Point. Use the remote controller to control the aircraft’s speed or altitude to avoid a collision during the Smart RTH process. As the aircraft returns, it will use the primary camera to identify obstacles as far as 300m in front, allowing it to plan a safe route home. Press and hold the Smart RTH button once to start the process, and press the Smart RTH button again to terminate the procedure and regain full control of the aircraft.

Low Battery RTH (Can be turned off in DJI GO 4 app)

The low battery level failsafe is triggered when the DJI Intelligent Flight Battery is depleted to a point that may affect the safe return of the aircraft. Users are advised to return home or land the aircraft immediately when prompted. The DJI GO 4 app will display a notice when a low battery warning is triggered. The aircraft will automatically return to the Home Point if no action is taken after a tensecond countdown. The user can cancel the RTH procedure by pressing the RTH button on the remote controller. The thresholds for these warnings are automatically determined based on the aircraft’s current altitude and distance from the Home Point.

The aircraft will land automatically if the current battery level can only support the aircraft long enough to descend from its current altitude. The user can still use the remote controller to alter the aircraft’s orientation during the landing process.

The Battery Level Indicator is displayed in the DJI GO 4 app, and is described below:

When the Critical Low battery level warning is triggered and the aircraft begins to land automatically, push the left stick upward to make the aircraft hover at its current altitude, giving you an opportunity to navigate to a more appropriate landing location.

The colored zones and markers on the battery level indicator bar reflect the estimated remaining flight time. They are automatically adjusted according to the aircraft’s current location and status.

Failsafe RTH

If the Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH will be automatically activated if the remote controller signal is lost for more than three seconds.

The aircraft will plan its return route and retrace its original flight route home. The user may cancel

Failsafe RTH to regain control when connection is reestablished.

RTH Procedure

1.Home Point is recorded automatically.

2.RTH procedure is triggered i.e., Smart RTH, Low-Battery RTH, and Failsafe RTH.

3.Home Point is confirmed and the aircraft adjusts its orientation.

4.a. The aircraft will ascend to the pre-set RTH attitude and then fly to the Home Point when the aircraft is further than 20 m from the Home Point.

b. When the aircraft is between 3 m and 20 m from the Home Point, it will return to the Home Point at the current altitude with the RTH at Current Altitude option enabled (the default setting in DJI GO 4) if flying at or above 2.5 m. It will ascend to 2.5 m then return to home if flying lower than 2.5 m.

MATRICE 200 Series User Manual

Note: If RTH at Current Altitude is disabled in DJI GO 4, the aircraft will land automatically when the aircraft is between 3 m and 20 m from the Home Point.

c. The aircraft will land automatically if RTH is triggered and the aircraft is less than 3 m from the home point.

5.The aircraft will hover 0.7 m above ground and wait for confirmation from the user. The aircraft will land and stop its motors after user confirmation.

Use the Failsafe RTH for example:

1. Record Home Point

2. Remote Control Signal Lost

3. Signal Lost for Extended Time

4. RTH (Adjustable Altitude)				5. Landing (After User Confirmation)
	Height over HP>Failsafe Altitude
	Elevate to Failsafe Altitude			Hovering at 0.7 meters above the Home Point
	Failsafe Altitude
	Height over HP<=Failsafe Altitude
Aircraft cannot return to the Home Point when GPS signal is weak ( [					] Less than 4
bars is considered a weak GPS signal) or unavailable.
User cannot control the aircraft while the aircraft is ascending to 65 feet (20 meters) from
the current altitude. However, users can press the RTH button once to exit ascending and
regain control.
The aircraft will automatically descend and land if RTH is triggered when the aircraft flies
within a 65 feet (20 meters) radius of the Home Point. The aircraft will stop ascending and
will return to the Home Point if the aircraft reaches 65 feet (20 meters) in altitude or beyond
during Failsafe.
The aircraft cannot avoid obstacles during Failsafe RTH if the Forward Vision System is
disabled. It is important to set a suitable RTH Altitude before each flight. Launch DJI GO 4,
enter camera and tap		to set Failsafe Altitude.

Failsafe Safety Notices

MATRICE 200 Series User Manual

The aircraft cannot return to the Home Point when GPS signal is weak ( [ ] displaying less than four bars) or is unavailable.

If you move the left stick when the aircraft is flying above 65 feet (20 meters) but below the pre-set Failsafe RTH altitude, the aircraft will stop ascending and immediately return to the Home Point.

Obstacle Avoidance During RTH

The aircraft can sense and actively attempt to avoid obstacles during RTH, provided that lighting conditions are adequate for the Forward Vision System. Upon detecting an obstacle, the aircraft will act as follows:

1.The aircraft will use the primary camera to identify obstacles as far away as 984 feet (300 meters) in front, allowing it to plan a safe route home.

2.The aircraft decelerates when an obstacle is sensed at 49 feet (15 meters) ahead.

3.The aircraft stops and hovers then starts ascending vertically to avoid the obstacle. Eventually, the aircraft will stop climbing when it is at least 16 feet (5 meters) above the detected obstacle.

4.RTH procedure resumes. The aircraft will continue flying to the Home Point at the current altitude.

5 meters

300 meters 15 meters

Obstacle Sensing is disabled during RTH descent. Proceed with care.

To ensure the aircraft returns home forwards, it cannot rotate during RTH while the Forward Vision System is enabled.

The aircraft cannot avoid obstacles beside or behind it.

Landing Protection Function

Landing Protection will activate during auto-landing.

1.Landing Protection determines whether the ground is suitable for landing. If so, the aircraft will land smoothly.

2.If Landing Protection determines that the ground is not suitable for landing, the aircraft will hover and wait for pilot confirmation. The aircraft will hover if it detects the ground is not appropriate for landing even with a critically low battery warning. Only when the battery level decreases to 0% will the aircraft land. Users retain control of aircraft flight orientation.

3.If Landing Protection is inactive, the DJI GO 4 app will display a landing prompt when the aircraft descends below 0.7 meters. Tap to confirm or pull down the control stick for 2 seconds to land when the environment is appropriate for landing.
