This AlphaBot2 robot kit is designed to use with an Arduino UNO compatible controller (not included). It features rich common robot functions including line tracking, obstacle avoiding, ultrasonic ranging, infrared remote control, Bluetooth communication, etc.

Thanks to the highly integrated modular design, it is fairly easy to assemble by a snap, with no soldering, no wiring. After a few minutes spent on hardware assembly, you're almost there, our open source demo codes are ready to help you get started fast.

The controller, which is Arduino UNO or Arduino UNO compatible is not included. You can get it separately here:

  • Arduino UNO R3 (Original from
  • CT-UNO (Arduino UNO R3 compatible from Cytron)
  • CT-UNO-SE (Arduino UNO R3 compatible special edition from Cytron)


  • AlphaBot2 employs a 2-layer structure to provide excellent stability and compatibility.
  • AlphaBot2-Base, the lower base chassis:
    • 5-ch infrared sensor, analog output, combined with PID algorithm, stable line tracking
    • Onboard modules like line tracking, obstacle avoiding, needs no messy wiring
    • TB6612FNG dual H-bridge motor driver, compared with L298P, it's more efficient, more compact, and less heating
    • Micro gear motor, with metal gears, low noise, high accuracy
    • Onboard RGB LEDs, true color lighting, pretty cool
  • AlphaBot2-Ar, the upper adapter board for controller:
    • Onboard Arduino interface, into which Arduino controller can be directly plugged
    • 0.96inch 128x64 yellow/blue dual color OLED
    • TLC1543 AD acquisition chip
    • PC8574 I/O expander, avoid I/O shortage
    • XBee connector, for connecting dual-mode Bluetooth module

Note: The AlphaBot2 does not come with the 14500 Li-ion batteries, we recommend get 14500 600mAh here.

AlphaBot2-Base consists of:

  1. AlphaBot2 control interface: for connecting sorts of the controller adapter board
  2. Ultrasonic module interface
  3. Obstacle avoiding indicators
  4. Omni-direction wheel
  5. ST188: reflective infrared photoelectric sensor, for obstacle avoiding
  6. ITR20001/T: reflective infrared photoelectric sensor, for line tracking
  7. Potentiometer for adjusting obstacle avoiding a range
  8. TB6612FNG dual H-bridge motor driver
  9. LM393 voltage comparator
  10. Micro gear motor reduction rate 1:30, 6V/600RPM
  11. Rubber wheels diameter 42mm, width 19mm
  12. Power switch
  13. Battery holder: supports 14500 batteries (not included)
  14. WS2812B: true color RGB LEDs
  15. Power indicator

AlphaBot2-Ar (Top) consists of:

  1. AlphaBot2 control interface: for connecting AlphaBot2-Base
  2. Arduino expansion header: for connecting Arduino shields
  3. Arduino interface: for connecting Arduino compatible controller, Arduino UNO R3, or CT-UNO
  4. XBee connector: for connecting dual-mode Bluetooth module, remotely control the robot via Bluetooth
  5. IR receiver
  6. PC8574: I/O expander, SPI interface
  7. Arduino peripheral jumpers
  8. TLC1543: 10-bit AD acquisition chip
  9. Buzzer
  10. 0.96inch OLED SSD1306 driver, 128x64 resolution
  11. Joystick

I am using Maker Uno as controller for AlphaBot2-Ar. But it doesn't work.
Maker Uno never power ON after switch ON the PWR Switch at bottom of base board.
I realize Maker Uno only can be thru 5V USB. Is there anywhere to make Maker Uno compatible with AlphaBot2-Ar?

Hi, you may drop an email to for technical assistance. Thanks :)
hi...this robot can use for competition in line follower and what i need for prepare this robot ( Kamalrudin , 09/03/2020 )
Hi, you may drop an email to for technical assistance. Our technical team will try their est to assist you. Thanks :)
But my bot cannot track line and oled also doesn't function.

Hi, you have to upload the program first. For more info please email to as here is for short inquires only. Thanks.
I want to know an information about AlphaBot2-Ar
I doesn't have UNO plus board
So, I use UNO R3 board.
My bot only can perform as object avoidance only.
it can't track line and OLED also doesn't function.
Any suggestions?
or I have to use UNO PLUS ?
( Saktisswaran, 26/02/2019 )
Hi, yes you may use any UNO board :)
