运行程序时树莓派重启

Question

当我运行使用以下代码时，我的 raspberry pi 重新启动：sudo python robot.py 我的 raspberry pi 通过机器人控制器 (Robohat)

连接到 4 个电机、一个平移和倾斜组件以及一个超声波传感器

import robohat, time, random
dist_l = 0
dist_r = 0
speed = 80
pan = 1
tilt = 0
tVal = 25 # 20 degrees is centre
pVal = 20 # 25 degrees is centre

robohat.init()
def doServos():# Set servo to wanted degrees
    robohat.setServo(pan, pVal)
    robohat.setServo(tilt, tVal)

end = "False"
while end == "False":

   def dist_check(): #gets distance
        pVal = 20
        tVal = 25
    doServos() #Centre the servos       
def servoPosGo():
    pVal2 = (90)
    robohat.setServo(pan, pVal2)
    robohat.setServo(tilt, tVal)
    dist_l = robohat.getDistance()
servoPosGo()
#Take right reading at 90 degrees


def servoPosGo2():
    pVal3 = (-60)
    robohat.setServo(pan, pVal3)
    robohat.setServo(tilt, tVal)
    dist_r = robohat.getDistance()
servoPosGo2()

doServos() #Centres the servos
dist_check()
if dist_r < 100 or dist_l < 100: #Is the distance greater than 100, and go which is greater but less than 100
    if dist_l > dist_r:
        robohat.spinLeft(speed)
        robohat.forward(speed)
        time.sleep(dist_l - 10)
        robohat.stop()
    elif dist_r > dist_l:
        robohat.spinRight(speed)
        robohat.forward(speed)
        time.sleep(dist_r - 10)
        robohat.stop()
    elif dist_l == dist_r: #If the two distnaces are the same, choose a   random one
        ran = random.randrange(1, 2)
        if ran == (1):
            robohat.spinLeft(speed)
            robohat.forward(speed)
            time.sleep(dist_l - 10)
            robohat.stop()
        elif ran = (2):
            robohat.spinRight(speed)
            robohat.forward(speed)
            time.sleep(dist_r - 10)
            robohat.stop()
elif dist_l > 100 or dist_r > 100: #If distance IS greater than 100, go forward and set end to true
    end = "True"
    robohat.forward(speed)
     if dist_r > dist_l:
        time.sleep(dist_r - 10)
     elif dist_l > dist_r:
        time.sleep(dist_l - 10)

Answer 1

给你的树莓派一个更强大的交流适配器。它应该至少有 1.2 A.

此外，请确保您的伺服系统不是由 RPi 供电，接地必须相同，并且只有伺服指令线连接到 RPi 引脚。还有一个事实是，RPi 向其 GPIO 提供 3.5V 输出，而大多数伺服系统需要 5V 电源和 cmd 线路。虽然其中一些可以在 cmd 线上使用较低的电压正常工作。

如果您没有将电机直接连接到 GPIO，则必须重新检查接地等。

有时会有助于在电源输入上添加大电容，这样突然的瞬变就不会震动你的树莓派导致重启。
