Case 02：均匀加速

简介​

控制cutebot均匀加速，直到达到最高速度。

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 time import *

# 创建Cutebot类的实例
cutebot = Cutebot()
# 创建变量cutebot_speed，用于保存cutebot智能赛车的速度值
cutebot_speed = 0

# 设置cutebot智能赛车的速度从0~100均匀加速
while True:
    if cutebot_speed > 100:
        cutebot_speed = 100
    cutebot.set_speed(cutebot_speed,cutebot_speed)
    cutebot_speed = cutebot_speed + 1
    sleep(0.02)

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。
from cutebot import *
from time import *
  1. 创建Cutebot类的实例。
cutebot = Cutebot()
  1. 创建变量cutebot_speed，用于保存cutebot智能赛车的速度值。
cutebot_speed = 0
  1. 设置cutebot智能赛车的速度从0~100均匀加速。
while True:
    if cutebot_speed > 100:
        cutebot_speed = 100
        cutebot.set_speed(cutebot_speed,cutebot_speed)
        cutebot_speed = cutebot_speed + 1
    sleep(0.02)

实验结果​

开启电源后，cutebot智能赛车的速度从0~100均匀加速。

思考​

如何让小车均匀加速后再均匀减速？
