智能小车避障算法设计Python,可以使用超声波传感器进行避障。当超声波传感器检测到前方有障碍物时,小车会自动停下或者转向避开障碍物。以下是一个简单的智能小车避障算法设计Python的示例代码:
```
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BOARD)
# 设置超声波传感器的引脚
TRIG = 11
ECHO = 12
GPIO.setup(TRIG, GPIO.OUT)
GPIO.setup(ECHO, GPIO.IN)
def distance():
# 发送超声波信号
GPIO.output(TRIG, GPIO.HIGH)
time.sleep(0.00001)
GPIO.output(TRIG, GPIO.LOW)
# 接收超声波信号
while GPIO.input(ECHO) == 0:
pulse_start = time.time()
while GPIO.input(ECHO) == 1:
pulse_end = time.time()
# 计算距离
pulse_duration = pulse_end - pulse_start
distance = pulse_duration * 17150
distance = round(distance, 2)
return distance
try:
while True:
dist = distance()
print("Distance: ", dist, "cm")
if dist < 30:
print("Obstacle detected!")
time.sleep(0.1)
except KeyboardInterrupt:
GPIO.cleanup()
```
该代码使用GPIO库来控制超声波传感器的引脚,并使用distance()函数来计算距离。当距离小于30cm时,程序会输出“Obstacle detected!”的提示信息。
