There is extremely high interest and curiosity in drone technology among students and teachers, but organized information on the topic is difficult to find. Although the Internet is abundant in links and videos on the subject, it is quite a chore to find exactly what you want without doing numerous searches and perusing many articles and videos. was created to provide accessible high-quality, meaningful curricula rooted in STEM principles and concepts.

We are not a “Drone Academy.” What we offer are multiple “stand-alone” curriculum options for teachers wanting to incorporate some type of drone curriculum into their programs. We have solutions for multiple grade levels — from elementary to middle schools to high schools to college-level needs. We also offer four areas of focus: theory and design, flight skills (by using indoor toy drones), programming the Tello drone, and preparing students to be successful at passing the FAA’s Remote Pilot Certification Exam by teaching the pertinent general knowledge.

All about the Tello™ Drone

First released in 2018, it was developed by Chinese companies Ryze Technology in collaboration with DJI

Innovations. DJI has been producing reputable consumer and professional drones for the past several

years. Ryze developed the “kid-friendly” Tello drone that combines DJI flight technology and an Intel

processor to create an inexpensive camera drone that also can be used to teach the basics of

programming. There are currently three versions of the drone (Tello, Tello EDU, and the RoboMaster

TT). We will show the commonalities and differences between them. Tello Info P a g e | 2 – Curriculum Designed for the STEM Classroom

• Video: HD720P-30FPS

• Format: JPEG (Photo); MP4 (Video)

• Electronic Image Stabilization: An image enhancement technique that uses electronic

processing to produce smooth images.


• Vision Positioning System: Consists of a camera and an infrared 3D module. This system can work in

a range of 0.3m to 30m high, but its optimal working conditions are 0.3m to 6m high.

• Drone Status Indicator: LED on the front that indicates the drone’s status while in use.


The basic Tello™ drone weighs only 80 grams, can fly for 13 minutes on its battery, is able to capture 5-

megapixel photos, and can shoot HD720 video. The drone can be controlled simply using a mobile app

on a smartphone (iOS or Android) or on an iPad or Android tablet and therefore doesn’t come with a

controller. As an additional purchase, you can add a specific controller if you prefer a traditional RC

transmitter feel. There will be more information about this controller later.

But the Tello in all its versions is more than a “toy drone.” The main thing that sets it apart is the Intel

technology inside. Because the Tello drone uses the same Intel processor that handles object

recognition in DJI drones, the Tello has the capability to respond to hand gestures — just like DJI’s more

high-end drones. It can even land in your hand and take off by being tossed in the air.

When flying in calm conditions, such as indoors, the Tello is incredibly stable and holds its position,

making it very easy to learn how to fly. However, because it is so lightweight, the drone doesn’t fly as

well in slight wind or breezy conditions. Tello Info P a g e | 3 – Curriculum Designed for the STEM Classroom

Equipped with a high-quality image processor, the Tello drone shoots incredible photos and videos. For

its low price, it has a better camera than more expensive drones in its category. Tello has two antennas

that make video transmission extra stable. The drone records the video directly to your mobile phone,

so you don’t have to store it on a memory card. Because it’s on your phone, it’s very easy to instantly

upload your video online to social media.

The standout feature of Tello is the fact that you can program it to perform specific routines. This is the

first time DJI has formally gotten into the “drones for education” department, something other

competing drone companies have been doing for years.

The drone can utilize Scratch or DroneBlocks as coding platforms. They are “drag-and-drop”

programming languages targeted at younger learners. Essentially, you can program the drone to fly

certain directions based on the “code” you have written (you actually drag code command “blocks”).

You can also download the app Swift Playgrounds to get a glimpse of text programming in its Tello

Space Travel game. If you opt to use Scratch or DroneBlocks to control the drone, then you can control

it from your computer. Swift Playgrounds is used on iPad or Mac systems. We will discuss these

programs in greater detail in the curriculum.

The Tello App

The downloadable Tello

App makes everything

easy. Even if you’re new to

drones, you can just grab

your mobile phone and fly

with the intuitive control

system. Impressive

maneuvers can be

performed with just a tap

on the screen.

In the app’s screen interface, we see both joysticks to control the drone and what the drone’s camera is

capturing. In this same interface, we see data such as battery strength, whether it is connected to the

Wi-Fi or Bluetooth™, and height and speed indications. We can also see buttons for photo and video

recording. Tello Info P a g e | 4 – Curriculum Designed for the STEM Classroom

We can access different functionalities such as takeoff and landing by sliding the screen’s scroll control.

And we can access the different flight modes:

• Throw & Go: You can throw the drone to a position in the air where it will hover.

• 8D Flips: Flip in 8 different directions.

• Up & Away: Record a short video while the drone moves away and rises.

• 360: Record a short video while rotating 360º.

• Circle: Record a short video while flying in a circle.

• Bounce Mode: Fly automatically between 0.5 and 1.2 meters.

Tello is super safe to fly indoors with its software and hardware protections. With a single tap, it can

take-off and land automatically. Its vision positioning system facilitates precise hovering. With Tello’s

high-capacity battery, it offers an impressively long flight time (13 minutes), giving it one of the longest

flight times in the mini-drone category. And when the battery gets low, alerts will go off. Also, even if

you lose the connection, the Tello can still land safely thanks to its failsafe protection.

Programmable with Drag-and-Drop

You can learn the basics of programming while having fun. As mentioned before, by using Scratch or

DroneBlocks, you can program your own flight patterns with the Tello basic. There are even more

advanced programming options in the other versions of Tello. You will find Tello the smallest and

smartest drone around. Tello Info P a g e | 5 – Curriculum Designed for the STEM Classroom

© Drone System Technologies, LLC – Licensing and Distribution Restrictions Apply

The drone comes with extra propellers, propeller guards, a battery, a micro-USB cable, and a propeller

removal tool. You should definitely purchase extra batteries (3-5 per drone) because the flight time is

only 13 minutes maximum, and the charge time is about 90 minutes.

So, if you want a powerful, capable, and fun drone, the basic Tello™ is for you! It has all the functionality

described above and still allows you to experience its programming capabilities using “drag-and-drop”

options. Education-wise, it would be great for elementary grades on up.

Tello EDU™ (black)

The Tello EDU™ drone is a slight “step up” from the basic version. It has all the same specifications and

features of the basic Tello drone but adds more programming capabilities. With the Tello EDU, students

can easily learn programming languages such as Scratch, DroneBlocks, Tello SDK, Swift, Python, and


You can also write code to command multiple Tello EDUs to fly in a “swarm” and develop amazing AI

(Artificial Intelligence) functions. It is an impressive and programmable drone perfect for education. The

Tello EDU Drone is an ideal companion for students engaged in STEAM-based learning.

Mission Pads

The Tello EDU drone comes with four tables or pads. These tables

are known as “Mission Pads.” The Mission Pad is a 15×15 cm

square table that serves as a pattern that can be identified by the

Tello EDU drone. Each side contains a unique pattern composed of:

• Planets: different patterns that indicate the ID

• A rocket: follow the direction of the x-axis

• An ID: number between 1 and 8

For advanced programming, the Mission Pads are a fantastic option

for increased precision. They not only serve as guiding points, but as

trigger mechanisms. Program with the specific information within each Mission Pad to expand your

options and push the limits of Tello EDU. You can write code that will enable your aircraft to recognize

each Mission Pad’s unique ID, as well as perform aerial acrobatics. Control a swarm of Tello EDUs and

bring your imagination to life! Tello Info P a g e | 6 – Curriculum Designed for the STEM Classroom

Tello SDK 2.0

The Tello EDU drone has a “Software Development Kit”, which serves as the basis for the development

of the different applications that can be carried out. On the Internet, you can find a user guide created

by Ryze Technologies which explains how to make the connections, all the different commands that the

drone accepts, and how to reset it to return to the initial mode.

Script Programming with Tello EDU

To run a script, it’s necessary to connect the computer to the Tello EDU drone. To do this, you must

connect to the Tello EDU Wi-Fi network. The name of the Wi-Fi network, by default, can be seen on your

available Wi-Fi choices or inside the drone when the battery is removed. It’s possible to change the

name of the network and add a password to prevent any stranger from taking control of the drone.

Some of the useable programming languages include Scratch, DroneBlocks, Tello SDK, Swift, Python,

and JavaScript.

Optional RC Controller (additional purchase)

The drone can be controlled simply using a mobile app on a

smartphone (iOS or Android) or on a tablet. However, if you

prefer a traditional RC transmitter feel, Ryze recommends using

the GameSir T1d controller. It’s very simple to connect through

Bluetooth™ within the Tello App, and you can use the

controller’s joysticks to take control of the drone. There’s also a

nifty holder for your phone to view the live video while flying.

This option might give the pilot a more secure feeling of control.

Connecting the GameSir T1d to the Tello App

NOTE: You cannot connect the GameSir controller to the Bluetooth™ dialogue of your phone. It can only

connect via the Tello mobile app. Follow the steps below to connect.

1. Enable Bluetooth™ on your phone.

2. Turn on the GameSir T1d controller.

3. Start the Tello App on your phone.

4. Tap the gear icon (left of center at the top of the screen).

5. Tap “Bluetooth controller settings”.

6. Tap on “GameSir T1d controller” and you will get confirmation “Connected”.

The GameSir controller will be connected and ready to use with the Tello. Tello Info P a g e | 7 – Curriculum Designed for the STEM Classroom

Swarms No Yes – several drones needed

With its Tello SDK option, the Tello EDU has support for drone “swarms.” A drone swarm is a group of

drones that can make decisions based on shared information. A great example of drone swarms is the

Intel drone display used in the Olympics, the Superbowl, and other venues in the last couple of years.

Another great example is the drone swarm used over the Bellagio fountains (YouTube link). Obviously,

you need more than one drone for a drone swarm.

If you plan to focus mainly on drag-and-drop programming, then the basic Tello is a fantastic choice. It’s

fun to fly on its own and will provide a great experience in the Tello App. If your budget allows and you

want to get into more advanced programming, the Tello EDU gives the option of additional

programming languages and the ability to support drone swarms. The Tello EDU is only $30 more than

the basic Tello.

RoboMaster TT™ (Iron Man red)

The RoboMaster TT (Tello Talent),

developed by DJI Education and

released in 2021, is an update to the

popular Tello EDU. It is an eyecatching “Iron Man” red and has the

noticeable addition of a

programmable LED light and dotmatrix screen. The drone can perform a string of movement and light commands that can be

programmed by the user. It can also perform coordinated movements in a swarm of RoboMaster TT

drones. This powerful educational drone makes coding simple and accessible to help introduce you to

the world of drones and AI programming. Tello Info P a g e | 8 – Curriculum Designed for the STEM Classroom
