rktellolib 1.0.4

A simple library to interface with the DJI Tello drone

RKTelloLib

In light of the many poorly-designed libraries to interact with the DJI (Ryze) Tello drone that either do way more than they should or don't do enough, I have taken the initiative to create this small library. It's a simple interface built upon the official Tello SDK that allows you to control and interact with the drone with minimal effort.

Installation

Install using PIP

$ pip install rktellolib

Install from Source

$ git clone https://github.com/ramujin/rktellolib.git
$ cd rktellolib
$ pip install -e .

Example Usage to Fly in a Square Pattern

from rktellolib import Tello

drone = Tello(debug=True, has_video=False)

drone.connect()
drone.takeoff()

drone.forward(100)
drone.cw(90)
drone.forward(100)
drone.cw(90)
drone.forward(100)
drone.cw(90)
drone.forward(100)
drone.cw(90)

drone.land()
drone.disconnect()

Example Usage to Stream Video

from rktellolib import Tello
import cv2

drone = Tello(debug=True, has_video=True)

drone.connect()

while True:
  frame = drone.get_frame()
  if frame is None:
    break

  cv2.imshow('rktellolib', frame)

  if cv2.waitKey(1) == 27: # ESC key
    break

drone.disconnect()
