For this guide, we’ll focus on Python, as it’s a popular and easy-to-learn language. However, the principles and concepts discussed can be applied to other programming languages as well.
Setting up the Tello Drone for Programming
Before you start programming, you’ll need to set up your Tello drone and connect it to your computer or mobile device. Follow these steps:
Step 1: Update the Tello Drone Firmware
Ensure your Tello drone is running the latest firmware. To do this:
- Open the Tello app on your mobile device.
- Tap on the “Settings” icon.
- Tap on “Firmware Update.”
- Follow the on-screen instructions to update the firmware.
Step 2: Connect the Tello Drone to Your Computer or Mobile Device
Connect your Tello drone to your computer or mobile device using the Tello app:
- Open the Tello app on your mobile device.
- Tap on the “Connect” button.
- Select your Tello drone from the list of available devices.
- Wait for the connection to establish.
Python Programming for Tello Drone
Now that you’ve set up your Tello drone, let’s dive into the world of Python programming.
Installing the Required Libraries
To program your Tello drone using Python, you’ll need to install the following libraries:
- tellopy: A Python library specifically designed for Tello drone programming.
- opencv-python: A computer vision library for image and video processing.
To install these libraries, open a terminal or command prompt and type:
pip install tellopy opencv-python
Basic Tello Drone Commands using Python
Using the tellopy library, you can control your Tello drone using Python commands. Here are some basic commands to get you started:
- Takeoff:
drone.takeoff() - Land:
drone.land() - Forward:
drone.forward(50)(move forward by 50 cm) - Backward:
drone.backward(50)(move backward by 50 cm) - Left:
drone.left(50)(move left by 50 cm) - Right:
drone.right(50)(move right by 50 cm) - Up:
drone.up(50)(move up by 50 cm) - Down:
drone.down(50)(move down by 50 cm)
These basic commands can be combined to create complex movements and sequences. For example:
drone.takeoff()
drone.forward(50)
drone.left(30)
drone.forward(20)
drone.land()
This script will take off the drone, move it forward by 50 cm, then left by 30 cm, and finally land the drone.
Advanced Tello Drone Programming Techniques
Now that you’ve mastered the basics, let’s explore some advanced programming techniques to take your Tello drone programming to the next level.
Object Tracking using OpenCV
Using OpenCV, you can track objects in real-time using your Tello drone’s camera. This can be achieved by:
- Capturing video feed from the drone’s camera using OpenCV.
- Applying object detection algorithms to identify and track objects.
- Adjusting the drone’s movement based on the object’s position and velocity.
Here’s an example code snippet to get you started:
“`
import cv2
from tellopy import Tello
Initialize the drone and camera
drone = Tello()
cap = cv2.VideoCapture(0)
while True:
# Capture frame from camera
ret, frame = cap.read()
# Apply object detection algorithm
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
faces = cv2.HaarDetectObjects(gray, cv2.CascadeClassifier('haarcascade_frontalface_default.xml'))
# Track the object and adjust drone movement
for (x, y, w, h) in faces:
cv2.rectangle(frame, (x, y), (x+w, y+h), (0, 255, 0), 2)
drone.forward(10) # Move forward by 10 cm
# Display the output
cv2.imshow('frame', frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
Release resources
cap.release()
cv2.destroyAllWindows()
“`
This code snippet captures video feed from the drone’s camera, detects faces using OpenCV’s Haar cascade classifier, and moves the drone forward by 10 cm whenever a face is detected.
Swarm Programming using Multiple Tello Drones
Swarm programming allows you to control multiple Tello drones simultaneously, creating a synchronized and mesmerizing aerial display. To achieve this, you’ll need:
- Multiple Tello drones
- A single computer or mobile device to control the drones
- A programming language to coordinate the drone movements
Here’s an example code snippet to get you started:
“`
import tellopy
Initialize multiple drones
drone1 = tellopy.Tello(‘192.168.10.1’) # Replace with the IP address of the first drone
drone2 = tellopy.Tello(‘192.168.10.2’) # Replace with the IP address of the second drone
Define a function to synchronize drone movements
def sync_move(drone1, drone2, direction, distance):
drone1.command(‘forward’, distance)
drone2.command(‘forward’, distance)
Take off and synchronize drone movements
drone1.takeoff()
drone2.takeoff()
sync_move(drone1, drone2, ‘forward’, 50)
sync_move(drone1, drone2, ‘left’, 30)
sync_move(drone1, drone2, ‘forward’, 20)
Land the drones
drone1.land()
drone2.land()
“`
This code snippet initializes two Tello drones, defines a function to synchronize their movements, and demonstrates a simple swarm programming example.
