What is this module called?

这个模块的名称是什么？

• Gyro Sensor

  陀螺仪传感器

• Ultrasonic Sensor

  超声波传感器

• Color Sensor

  颜色传感器

• Touch Sensor

  触感传感器

Which of the modules should NOT be plugged in to Port 1, 2, 3, and 4?

哪一个模块不应该接入Port 1、2、3、4的接口？

Which of the following can make driving base keep running until ultrasonic sensor detect distance that is less than 20cm?

以下哪一个程序可以让Driving Base不断向前走直到超声波传感器侦测到距离小于20cm？

• 
• 
• 
• 

Why driving base won't move forward with this coding?

为何此程序无法让Driving Base前进？

• Motors B & C is not set before start moving

  没有提前设置好Motor B和C

• Motor Speed is not set before start moving

  没有提前设置好电机的速度

• The Ultrasonic coding should be "wait until distance is less than 20cm"

  超声波的设定应该要换成 “当距离小于20cm”

• The Ultrasonic Port should change

  超声波的接口应该换去另一个接口

Why do we put a wait for second before we start moving using ultrasonic sensor for distance detection?

但我们使用超声波侦测距离的方式来让Driving Base走时，为何要在起跑前加一个等待1秒钟？

• To ensure Ultrasonic reading is stable before we start moving

  确认超声波读取稳定，才向前走

• Stay calm before moving

  先冷静再走

• Wait servo motor stay stable before start moving

  先等伺服电机稳定，再向前走

• To enable Ultrasonic

  用来启动超声波传感器
