Module

Introduction

The VEX AIR Drone features a module port, which can connect to various VEX AIR Modules. These allow the drone to drop and hold different payloads.

Note: Only the Motorized Hook Module and the Magnet Module can be controlled with these methods.

Below is a list of all available methods:

Actions

• drop_payload – Releases payloads.

• hold_payload – Allows payloads to be collected.

Getters

• get_type – Returns the type of module that is attached to the drone.

• is_holding – Returns the current state of the Motorized Hook Module as a Boolean.

Actions

drop_payload

drop_payload releases the currently held payload.

Usage:

drone.module.drop_payload()

Parameters	Description
	This method has no parameters.

# Demonstrate the Motorized Hook Module moving
drone.take_off(starting_altitude=800)
wait(1, SECONDS)
drone.module.hold_payload()
wait(2, SECONDS)
drone.module.drop_payload()
drone.land()

hold_payload

hold_payload picks up the payload.

Usage:

drone.module.hold()

Parameters	Description
	This method has no parameters.

# Demonstrate the Motorized Hook Module moving
drone.take_off(starting_altitude=800)
wait(1, SECONDS)
drone.module.hold_payload()
wait(2, SECONDS)
drone.module.drop_payload()
drone.land()

Getters

get_type

get_type returns one of the following based on the module currently attached to the drone:

• DroneModuleType.HOOK – The Motorized Hook Module is attached.

• DroneModuleType.MAGNET – The Magnet Module is attached.

• DroneModuleType.PASSIVE – The Passive Hook Module is attached or no module is attached.

Usage:

drone.module.get_type()

Parameters	Description
	This method has no parameters.

# Display what module is attached to the drone
# Change the module with Propeller Lock on during project
while True:
    clear_console()
    print(drone.module.get_type())
    wait(0.2,SECONDS)

is_holding

is_holding returns a Boolean indicating whether the Motorized Hook Module is currently in the hold state, or in the drop state.

• True – The Motorized Hook Module is lowered.

• False – The Motorized Hook Module is raised.

Note: This method only works with the Motorized Hook Module.

Usage:

drone.module.is_holding()

Parameters	Description
	This method has no parameters.

# Create a custom button to toggle the Motorized Hook Module
def hook_toggle():
    if drone.module.is_holding():
        drone.module.drop_payload()
    else:
        drone.module.hold_payload()
