Aircraft
The RoboMaster TT contains a flight controller, video downlink system, Vision Positioning System, propulsion system, and a Flight Battery. Refer to the aircraft diagram in the Product Profile section.
Flight Modes
The RoboMaster TT has two flight speeds that you can select when flying the aircraft manually: · Slow (default): The maximum flight attitude angle is 9° and the maximum flight speed is 6.7 mph
(10.8 kph). · Fast: The maximum flight attitude angle is 25° and the maximum flight speed is 17.8 mph (28.8 kph).
When flying the RoboMaster TT manually the aircraft utilizes its Vision Positioning System to automatically stabilize itself. If the conditions are such that the Vision Positioning System is unavailable the aircraft automatically changes to Attitude mode. The aircraft automatically changes to Attitude mode (ATTI mode) when the Vision Positioning System is unavailable. In Attitude mode the aircraft is not able to position itself and so is easily affected by its surroundings. Environmental factors such as wind can result in horizontal shifting, which may present hazards, especially when flying in confined spaces. When the aircraft enters Attitude mode, land in a safe place as soon as possible to avoid hazards.
· To switch from Slow to Fast you must read and agree to the disclaimers and warnings that appear in the Tello app. Make sure you understand the differences between the two flight speeds.
· Failsafe Protection automatically initiates landing if the mobile device’s signal is weak or is lost for 50 seconds, or the Tello app crashes.
Vision Positioning System
The Vision Positioning System helps the aircraft maintain its current position. With the help of the Vision Positioning System, the aircraft can hover in place more precisely and fly indoors or outdoors in windless conditions. The main components of the Vision Positioning System are a camera and a 3D infrared module located on the underside of the aircraft.

Vision Positioning System

ROBOMASTER TT TELLO TALENT User Manual
Using the Vision Positioning System
The Vision Positioning System is activated automatically when the aircraft is turned on. No further action is required. The Vision Positioning System is only effective when the aircraft is at altitudes of 1.0 to 98.4 ft (0.3 to 30 m) and works best at altitudes of 1.0 to 19.7 ft (0.3 to 6 m). If the aircraft is beyond this range, the Vision Positioning function may be affected, so extra caution is required.
· The performance of the Vision Positioning System is affected by the surface being flown over. The aircraft automatically changes to Attitude mode when the Vision Positioning System is unavailable. In Attitude mode the aircraft is not able to position itself. Operate the aircraft with great caution in the following situations, which may cause the aircraft to enter Attitude mode: a. Flying at high speed below 2 ft (0.5 m). b. Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green). c. Flying over highly reflective surfaces. d. Flying over water or transparent surfaces. e. Flying over moving surfaces or objects. f. Flying in an area where the lighting changes frequently or drastically. g. Flying over extremely dark (< 300 lux) or bright (> 100,000 lux) surfaces or towards bright sources of light (e.g. towards sunlight). h. Flying over surfaces without clear patterns or texture. i. Flying over surfaces with identical repeating patterns or textures (e.g. tiling). j. Flying over small and fine objects (e.g. tree branches or power lines). k. Flying at high speed of over 5 m/s at 4 ft (1 m).

Flight Modes, Functions, and Warnings
Flight Modes
To avoid serious injury and property damage, observe the following rule: 1. DO NOT switch from Standard mode to Fast mode unless you are sufficiently familiar with
the aircraft’s behavior in each flight mode.
1. Standard mode (default): The aircraft utilizes the Vision Positioning System to automatically stabilize itself. The maximum flight attitude angle is 9° and the maximum flight speed is 9 mph (14.4 kph).
2. Fast mode: The aircraft utilizes the Vision Positioning System to automatically stabilize itself. The maximum flight attitude angle is 25° and the maximum flight speed is 18 mph (28.8 kph).
To switch from Standard mode to Fast mode users must read and agree to the disclaimers and warnings that appear in the Tello app. Make sure you understand the differences between the two flight modes. The aircraft will revert to Attitude mode when the Vision Positioning System is unavailable. In Attitude mode, the aircraft is easily affected by its surroundings, which may result in horizontal shifting. Therefore, the aircraft cannot position or auto-brake in this mode. When the aircraft enters Attitude mode, land in a safe place as soon as possible to avoid hazards. Only land the aircraft on flat surfaces. DO NOT land the aircraft over water, grass or sand. When using PalmLand, ensure your palm is right under the aircraft and keep your palm flat.
Low Battery
1. When battery warnings are triggered, promptly bring the aircraft back or land the aircraft to avoid losing power during flight and causing damage to the aircraft, property, animals, and people.
2. When the Critical Battery Level warning appears the aircraft will start to descend automatically. You may push the throttle up to maintain the aircraft’s altitude and navigate the aircraft away from people and obstacles to a more appropriate location for landing.
Vision Positioning System
1. The Vision Positioning System cannot work properly over surfaces that do not have clear pattern variations. The Vision Positioning System is only effective when the aircraft is at altitudes of 0.3 to 10 m. The Vision Positioning System works best at altitudes of 0.3 to 6 m. If the aircraft is beyond this range, the Vision Positioning function may be affected, so extra caution is required.
14

2. DO NOT fly over reflective surfaces such as water or snow, as these terrains may affect the performance of the Vision Positioning System.
3. Note that the Vision Positioning System may not function properly when the aircraft is flying too fast (over 18 mph (28.8 kph) at 6.6 ft (2 m) or over 11 mph (18 kph) at 3.3 ft (1m)).
4. Be extra cautious when in any of the following situations: a. Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green); b. Flying over transparent surfaces; c. Flying over moving surfaces or objects; d. Flying in an area where the lighting changes frequently or drastically; e. Flying over extremely dark (< 10 lux) or bright (> 10,000 lux) surfaces; f.

ROBOMASTER TT
Mission Pad and Flight Map User Guide
V1.0 2021.04

Introduction
Mission pads and flight maps are accessories used for programming the RoboMaster TT (Tello Talent): The vision sensor of the drone detects the IDs of different mission pads and returns the relevant threedimensional coordinates in order to execute the corresponding programming commands. TT comes standard with four mission pads with different patterns on the front and back, for a total of eight IDs. The patterns on mission pad consist of three parts: a small rocket, the mission pad ID, and planets.
Small rocket
Mission pad ID
Planets

Small rocket: This represents the positive direction of the x-axis in the mission pad coordinate system. Mission pad ID: The pads are numbered 1-8, allowing users to distinguish between different mission pads. Planets: TT recognizes the ID of the mission pad by detecting the arrangement of the planets and obtains the coordinate values in the coordinate system of the mission pad.
TT supports 3×3 m and 5×5 m flight maps, which can be regarded as large mission pads used in the same way with the flight maps, TT can perform single- drone fixed-point flight and multi-drone formation flight. The pattern of the flight map is composed of DJI Logo, decorative pattern, and planets.

Decorative pattern
Small planets DJI Logo

Decorative pattern Small planets DJI Logo

DJI logo: This represents the positive direction of the x-axis in the mission pad coordinate system. Decorative pattern: For decoration. Planets: TT recognizes the ID of the fight map by detecting the arrangement of the planets and obtains the coordinate values in the coordinate system of the flight map. Download and print the source files of the flight maps or purchase them from a dealer. Note that the maps must be printed on matte, textured, rough, and non- reflective material so they can be recognized by the vision sensor of the drone.

About the Mission Pad Coordinate System
The mission pad pattern contains a three-dimensional coordinate system, where the origin is at the center and the mission pad is a plane described by an x-axis and y-axis. Each mission pad provides an independent relative coordinate system. The coordinate systems of different mission pads do not affect each other, so they can be combined and placed as required.

Operations
The mission pads only work with TT or Tello EDU drones that support SDK 2.0 or later versions. 1. Mission pad placement
Place the mission pad on a level surface and adjust the orientation of the rocket as needed. 2. Enable TT mission pad detection
· Place TT in the center of the mission pad and enter the SDK mode (refer to the RoboMaster TT SDK instructions for details).
· After entering SDK mode, enable the mission pad detection function of TT with the “mon” command.
· Enable forward or downward-looking mission pad detection with the “mdirection x” command as needed.
3. Have TT recognize the mission pad Command the TT to take off and hover. Instruct Tello to recognize the mission pad using the mid parameter in the SDK and perform corresponding flight actions based on the coordinates and ID information.

If recognition succeeds, the drone will fly to the coordinate point (0, 0, 100) and then to the coordinate point (100, 100, 100) in the mission pad coordinate system along an arc at a speed of 40 cm/s. If recognition fails, it will hover, return “Error. Not valid marker”, and wait for the next command.

• The arc is the short arc of the only circle formed by the current position of the drone, (0, 0, 100) and (100, 100, 100). If the three points are on a straight line or the radius of the resulting circle is not within the range of 0.5 m – 10 m, an error is returned.

Command
jump x y z speed yaw m(id1) m(id2)

Description
Tello flies to point (x,y,z) of the mid1 coordinate system and hovers, recognizes the mid2 mission pad, and rotates to the set yaw value at position
(0,0,z) in the mid2 coordinate system

Possible response
ok/error + Error message

Example: jump 100 100 100 40 90 m1 m2
Description: TT detects the mission pad with ID 1 with the enabled mission pad detection function. If recognition succeeds, TT will fly to (100, 100, 100) in the mission pad coordinate system at the speed of 40 m/s, hover, and attempt to recognize the mission pad with an ID of 2. If this mission pad is recognized, the drone will rotate to a position 90° relative to the x-axis in the coordinate system of the ID 2 pad. If recognition fails in either recognition process, the drone will hover and return “Error. Not valid marker”.

TELLO Status
When the host computer sends “command” to Tello UDP port 8889 to enter the SDK mode, Tello will send Tello status information to UDP port 8890 of the host computer. The data is a string, and the content is as follows: “mid:%d;x:%d;y:%d;z:%d;mpry:%d,%d,%d;pitch:%d;roll:%d;yaw:%d;vgx:%d;vgy%d;vgz:% d;temp l:%d;temph:%d;tof:%d;h:%d;bat:%d;baro:%f;rn”

Description
· Mid: For the detected ID of the mission pad, -2 will be returned if the mission pad detection function is not enabled, and -1 if the function is enabled but no pad is detected.
· x: The x-axis coordinate of the drone relative to the detected mission pad (in centimeters). -200 will be returned if the mission pad detection function is not enabled, and -100 if no pad is detected.
· y: The y-axis coordinate of the drone relative to the detected mission pad (in centimeters). -200 will be returned if the mission pad detection function is not enabled, and -100 if no pad is detected.
· z: The z-axis coordinate of the drone relative to the detected mission pad (in centimeters). -200 will be returned if the mission pad detection function is not enabled, and -100 if no pad is detected.
· mpry: The pitch, yaw, and roll angles and degrees of the drone in the mission pad. If the mission pad is not detected, 0 will be returned.

If the mission pad is outside of TT’s recognition area, TT may not be able to detect the mission pad, and mid commands will be invalid. We recommend you place the mission pad on a clear textured surface. Avoid placing it on pure black or pure white backgrounds, otherwise TT may not be able to recognize the mission pad. When using the mission pad, ensure that the ambient light is moderate. Too little or too much light will affect the recognition of the mission pad. When the forward-looking camera is used to detect the mission pad, the mission pad commands mentioned above cannot be used.

Flight Map Coordinate System
The flight map pattern contains a three-dimensional coordinate system, where the origin is at the center and the flight map is a plane described by an x-axis and y-axis.
Y
X
Operations
The flight maps only work with TT or Tello EDU drones that support SDK 3.0 or later versions. 1. Flight map placement
Lay the flight map on a level surface and adjust the orientation of the DJI logo as needed. 2. Enable TT mission pad detection
· Place TT in the center of the flight map and enter the SDK mode (refer to the Tello SDK instructions for details).
· After entering SDK mode, enable the mission pad detection function of TT with the “mon” command. · Enable forward or downward-looking mission pad detection with the “mdirection x” command
as needed. 3. Have TT recognize the flight map
Command the TT to take off and hover. Instruct Tello to recognize the flight map using the mid parameter in the SDK and perform corresponding flight actions based on the coordinates and ID information.
Command Descriptions
The flight map commands are the same as those of the mission pad. Note that the ID of the flight map is 12.
Effective flight map recognition range
Recognizable height range: 0.9 ­ 2.0 m Recognizable horizontal range: The effective programming range is 2.8 m×2.8 m
When the flight map is used, the instructions for using mission pads must also be followed. Do not place small mission pads and other obstructions directly on the flight map to avoid interference with flight map recognition by the downward-looking camera. During formation flight, do not have one drone to fly directly under another drone, as this may block the recognition of the flight map. When planning the formation flight path, you need to appropriately plan the routes of each drone to avoid collisions, which may cause explosions.

ROBOMASTER TT
SDK 3.0 User Guide
V1.0 2021.04

Overview
The TT SDK connects to drones via Wi-Fi UDP protocol, allowing users to control drones through text commands. After installing the RoboMaster SDK, users can control the TT product, including the open-source TT controller and the drone itself. For specific instructions, visit the following website: https://robomaster-dev.readthedocs.io/latest/
Safety Function
After Tello executes the current command, if no command input is received (other than the [TELLO] battery?” command sent by the open-source controller for the battery status) within 15s, it will automatically land.
Resetting Wi-Fi
In the power-on state, long-press the power button for 5s, during which, the drone will reboot after the status indicator goes out. When the status indicator quickly flashes yellow, the SSID and password of the Wi-Fi network will be reset to their factory default settings, with no password required by default.
Architecture
Users can use a Wi-Fi network to connect the Tello drone to a PC, Mac, or mobile device.

Tello Command Types and Results
The SDK commands received by Tello can be grouped into three basic types.
Control command (xxx) Tello returns “ok” if the command was executed successfully. Tello returns “error” or a result code if the command failed.
Setting command (xx a) Setting command (xx a) will attempt to set a new sub- parameter value (a). Tello returns “ok” if the command was executed successfully. Tello returns “error” or a result code if the command failed.
Read command (xx?) Read the real-time sub-parameter value.
