模块

介绍

VEX AIR 无人机配备一个模块端口，可连接各种 VEX AIR 模块。这些模块使无人机能够投放和承载不同的有效载荷。

**注意：**这些方法仅适用于电动钩模块和磁铁模块。

以下是所有可用方法的列表：

行动

• drop_payload – Releases a payload using the attached module.

• hold_payload – Holds a payload using the attached module.

吸气剂

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

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

行动

drop_payload

drop_payload releases a payload using the attached module. The Motorized Hook Module opens its hook, and the Magnet Module turns its magnet off.

**注意：**此方法仅适用于电动钩模块和磁铁模块。

用法：

drone.module.drop_payload()

参数	描述
	该方法没有参数。

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

hold_payload

hold_payload holds a payload using the attached module. The Motorized Hook Module closes its hook, and the Magnet Module turns its magnet on.

**注意：**此方法仅适用于电动钩模块和磁铁模块。

用法：

drone.module.hold_payload()

参数	描述
	该方法没有参数。

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

吸气剂

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.

用法：

drone.module.get_type()

参数	描述
	该方法没有参数。

# 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.

**注意：**此方法仅适用于电动挂钩模块。

用法：

drone.module.is_holding()

参数	描述
	该方法没有参数。

# 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()

controller.button5.pressed(hook_toggle)
