The DJI Ryze Tello drone is a relatively low cost, indoor, commercial drone. It exposes an SDK which lets users connect to the drone and control it programmatically.

This package implements a subset of the SDK with the specific goal of making it easy to write feedback controllers for the Tello.

Basic Usage

The most basic use of Tello Control is to takeoff, land, and send RC commands to the drone.:

import sys
import time

from tello_control import Tello, TelloCommand

tello = Tello()

# Try connecting to the Tello
if not tello.connect():
  print("Could not connect to Tello")
  sys.exit(1)

# Try commanding the Tello to takeoff
if not tello.send_command(TelloCommand.TAKE_OFF, wait_for_success=True):
  print("Takeoff failed")
  sys.exit(1)

start_time = time.time()

# Fly for 10 seconds
while time.time() - start_time < 10::
  # Command the Tello in the Z direction
  tello.send_command(TelloCommand.RC, 0, 0, 20, 0)

  # Wait 0.1 seconds between each command
  time.sleep(0.1)

# Land the Tello
tello.send_command(TelloCommand.LAND, wait_for_success=True)

# Disconnect from the Tello
tello.disconnect()
