Layout Introduction

4WD MiniQ Complete Kit (SKU:ROB0050)

Function about every component:

  • Infrared transmitter:transmit the infrared signal, the signal can be used for detecting obstacles
  • Infrared receiver:receive infrared signal, the signal can be used for obstacle avoidance
  • Photosensitive diode:sensitive with the light, so it can help you get some information about the light
  • Button:can be programmed for your idea
  • RGB LED:you can change its color use your code, it can show as an alarm and other things you want
  • USB port:download your code and let your robot talk to your computer
  • Buzzer(passive):be an alarm bell or sing a simple song
  • Controller:runs your code
  • Motor:can be controlled to run forward or backward, so that the car can turn left or right freely
  • Reset button;Reset the robot, the program in the robot will runs again from its initiation
  • Power switch:power switch of the robot
  • Power port:power provided from this port
  • Charge port: if your batteries can be charged, you can charge them from this port thus they can be hold in the car
  • Infrared line-follow sensor: can be used for detecting for white or black lines
