How to Arm Drone Using DroneKit Python: Simple Guide

To arm a drone using dronekit in Python, first connect to the vehicle, then set vehicle.armed = True. Wait until the vehicle confirms it is armed before proceeding.

Syntax

The basic steps to arm a drone using DroneKit Python are:

• connect(): Connect to the drone.
• vehicle.armed = True: Command the drone to arm.
• while not vehicle.armed: Wait loop until the drone confirms it is armed.

python

from dronekit import connect
import time

# Connect to the vehicle
vehicle = connect('connection_string', wait_ready=True)

# Arm the vehicle
vehicle.armed = True

# Wait until the vehicle is armed
while not vehicle.armed:
    print('Waiting for vehicle to arm...')
    time.sleep(1)

Example

This example shows how to connect to a drone, arm it, and confirm the arming status with printed messages.

python

from dronekit import connect
import time

# Connect to the vehicle (replace '127.0.0.1:14550' with your connection string)
vehicle = connect('127.0.0.1:14550', wait_ready=True)

print('Connected to vehicle')

# Arm the vehicle
vehicle.armed = True

# Wait until the vehicle is armed
while not vehicle.armed:
    print('Waiting for vehicle to arm...')
    time.sleep(1)

print('Vehicle is armed!')

# Close vehicle object before exiting
vehicle.close()

Output

Connected to vehicle
Waiting for vehicle to arm...
Waiting for vehicle to arm...
...
Vehicle is armed!

Common Pitfalls

Common mistakes when arming a drone with DroneKit Python include:

• Not waiting for the vehicle to be ready before arming.
• Trying to arm without setting the mode to a guided or appropriate mode first.
• Not checking if the drone is already armed before setting vehicle.armed = True.
• Ignoring safety checks like GPS lock or pre-arm checks that prevent arming.

Always ensure the drone is in the correct mode and ready state before arming.

python

from dronekit import connect, VehicleMode
import time

vehicle = connect('127.0.0.1:14550', wait_ready=True)

# Wrong: Arming without setting mode
vehicle.armed = True  # May fail if mode is not set

# Right: Set mode before arming
vehicle.mode = VehicleMode('GUIDED')
while not vehicle.mode.name == 'GUIDED':
    print('Waiting for mode change...')
    time.sleep(1)

vehicle.armed = True
while not vehicle.armed:
    print('Waiting for vehicle to arm...')
    time.sleep(1)

Quick Reference

Summary tips for arming a drone using DroneKit Python:

• Always connect and wait for vehicle readiness.
• Set the vehicle mode to GUIDED before arming.
• Set vehicle.armed = True to arm.
• Use a loop to wait until vehicle.armed is True.
• Check pre-arm conditions like GPS lock and battery status.

Key Takeaways

Connect to the drone and wait until it is ready before arming.

Set the vehicle mode to GUIDED before setting vehicle.armed = True.

Always wait in a loop until the drone confirms it is armed.

Check pre-arm safety conditions to avoid arming failures.

Close the vehicle connection properly after operations.
