Recently, a junior high school student in Xiangyang, Hubei Province invented an intelligent anti-collision stroller. According to the inventor Liu Jie, this stroller mainly has the functions of automatic braking, collision avoidance, diaper changing and so on.
Liu Jie introduced that there are automatic braking devices on the handles and wheels of the stroller. When the parents' hands leave the handle of the stroller, the rudder will drive the braking device to brake the stroller; A humidity sensor is designed at the bottom of the stroller. When the humidity is too high, the alarm light will light up to remind parents to change their diapers.
In addition, there is an ultrasonic ranging sensor in front of the stroller. When the distance between the object and the stroller is less than 20 cm, the motor vibration module on the handle will work to remind parents to take protective measures in time.
