保险杠开关

介绍

The Bumper Switch is a mechanical switch that completes a circuit when pressed, allowing the robot to detect presses and releases.

This page uses bumper_1 as the example Bumper Switch name. Replace it with your own configured name as needed.

以下是所有方法的列表：

检查器 — 检查肩键开关当前是否被按下。

• pressing — Returns whether the Bumper Switch is being pressed.

回调函数——当肩键开关被按下或释放时运行代码。

• pressed — Registers a function to be called when the Bumper Switch is pressed.

• released — Registers a function to be called when the Bumper Switch is released.

构造函数 — 手动初始化和配置碰撞开关。

• Bumper — Create a Bumper Switch.

pressing

pressing returns an integer indicating whether the Bumper Switch is being pressed. This can be used to check if the robot bumps into other objects.

• 1 — The Bumper Switch is being pressed.

• 0 — The Bumper Switch is not being pressed.

Usage:
bumper_1.pressing()

参数	描述
	该方法没有参数。

# Back up and turn if bumper switch 
# is pressed
while True:
    drivetrain.drive(FORWARD)
    if bumper_1.pressing():
        drivetrain.drive_for(REVERSE, 100, MM)
        drivetrain.turn_for(RIGHT, 90, DEGREES)

pressed

pressed registers a function to be called when the Bumper Switch is pressed.

Usage:
bumper_1.pressed(callback, arg)

参数	描述
callback	先前定义的 函数 在按下保险杠开关时执行。
arg	Optional. A tuple containing arguments to pass to the callback function. See Functions with Parameters for more information.

# Drive forward when bumper switch 
# is pressed
def bumper_pressed():
    drivetrain.drive_for(FORWARD, 100, MM)

bumper_1.pressed(bumper_pressed)

released

released registers a function to be called when the Bumper Switch is released.

Usage:
bumper_1.released(callback, arg)

参数	描述
callback	先前定义的 函数 在保险杠开关释放时执行。
arg	Optional. A tuple containing arguments to pass to the callback function. See Functions with Parameters for more information.

# Drive reverse when bumper switch 
# is released
def bumper_released():
    drivetrain.drive_for(REVERSE, 100, MM)

bumper_1.released(bumper_released)

构造函数

Constructors are used to manually create Bumper objects, which are necessary for configuring a Bumper Switch outside of VEXcode.

Bumper Switch

Bumper creates a Bumper Switch.

Usage:
Bumper(smartport)

范围	描述
smartport	保险杠开关所连接的智能端口，记为 PORTx，其中 x 为端口号。

bumper_1 = Bumper(PORT1)
# Back up and turn if bumper switch pressed
while True:
    drivetrain.drive(FORWARD)
    if bumper_1.pressing():
        drivetrain.drive_for(REVERSE, 100, MM)
        drivetrain.turn_for(RIGHT, 90, DEGREES)
