保险杠#

介绍#

保险杠是一个机械开关，按下时会接通电路，使机器人能够检测到按下和释放动作。

以下是所有可用方法的列表：

检查器 – 检查保险杠传感器当前是否被按下。

  • pressed – Returns whether the Bumper Sensor is being pressed.

回调函数——当保险杠被按下或释放时运行的代码。

  • on_pressed – Calls a function when the Bumper Sensor is pressed.

  • on_released – Calls a function when the Bumper Sensor is released.

获取器#

pressed#

pressed returns a boolean indicating whether or not the bumper was pressed.

  • True – The Bumper Sensor is being pressed.

  • False – The Bumper Sensor is not being pressed.

Usage:
bumper.pressed()

参数

描述

此方法没有参数。

 
def main():
    # Stop when the Left Bumper is pressed
    drivetrain.drive(FORWARD)
    while True:
        if left_bumper.pressed():
            drivetrain.stop()
        wait(5, MSEC)

# VR threads — Do not delete
vr_thread(main)

打回来#

on_pressed#

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

Usage:
bumper.on_pressed(callback)

参数

描述

callback

预先定义的一个函数，当保险杠传感器被按下时执行。

 
def bumper_pressed():
    # Reverse when the bumper is pressed
    drivetrain.drive_for(REVERSE, 100, MM)
    drivetrain.stop()

def main():
    # Drive forward until the left bumper is pressed
    drivetrain.drive(FORWARD)
    left_bumper.on_pressed(bumper_pressed)

# VR threads — Do not delete
vr_thread(main)

on_released#

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

Usage:
bumper.on_released(callback)

参数

描述

callback

预先定义的一个函数，当保险杠传感器释放时执行。

 
def bumper_released():
    # Display a message
    brain.print("Bumper released!")

def main():
    # Hit and back away from an object
    left_bumper.on_released(bumper_released)
    drivetrain.drive_for(FORWARD, 600, MM)
    drivetrain.drive_for(REVERSE, 100, MM)

# VR threads — Do not delete
vr_thread(main)
