Case 04：自动转向灯

简介​

让Cutebot智能赛车按照随机路线行驶，并且自动打开转向灯。

准备编程环境​

准备编程环境请参考：准备编程环境

示例代码​

from cutebot import *
from random import *
from time import *

# 创建Cutebot类的实例
cutebot = Cutebot()

# 通过控制cutebot智能赛车的左右轮的速度为（0， 100）之间的随机值,并根据智能赛车的行驶方向自动点亮转向灯
while True:
    left_speed = randint(0, 100)
    right_speed = randint(0, 100)
    if left_speed > right_speed:
        cutebot.set_light(RGB.left,0,0,0)
        cutebot.set_light(RGB.right,255,255,0)
    if left_speed < right_speed:
        cutebot.set_light(RGB.left,255,255,0)
        cutebot.set_light(RGB.right,0,0,0)
    cutebot.set_speed(left_speed,right_speed)
    sleep(2)

代码详解​

  1. 导入程序所需要的模块：cutebot模块包含对Cutebot智能赛车操作的类和函数，time模块包含对时间操作的函数，random模块包含产生随机数的函数。
from cutebot import *
from random import *
from time import *
  1. 创建Cutebot类的实例。
cutebot = Cutebot()
  1. 通过控制cutebot智能赛车的左右轮的速度为（0， 100）之间的随机值,并根据智能赛车的行驶方向自动点亮转向灯。
while True:
    left_speed = randint(0, 100)
    right_speed = randint(0, 100)
    if left_speed > right_speed:
        cutebot.set_light(RGB.left,0,0,0)
        cutebot.set_light(RGB.right,255,255,0)
        if left_speed < right_speed:
            cutebot.set_light(RGB.left,255,255,0)
            cutebot.set_light(RGB.right,0,0,0)
            cutebot.set_speed(left_speed,right_speed)
    sleep(2)

实验结果​

开启电源后，cutebot智能赛车以随机的轨迹行驶，并根据智能赛车的行驶方向自动点亮转向灯。

思考​

当小车左右轮速度一致时，如何通过编程让cutebot智能赛车的两个车头灯同时点亮呢？
