Description
The AlphaBot2 robot kit is designed to use with the BBC micro:bit (not included) and features a great list of popular robot features including line tracking, obstacle avoiding, ultrasonic ranging, Bluetooth remote control (via Android app), RGB LEDs, a buzzer and more!
Thanks to the highly integrated modular design, it's very easy to assemble without any soldering or fiddly wiring. After a few minutes assembling the kit, you're ready to code!
The user guide can be found here.
Important notes:
- This robot requires a BBC micro:bit which is not included but can be purchased here.
- 3.6V 14500 rechargeable lithium batteries with at least 800mAh capacity are required but not included (coming soon to the store!). AA batteries will not work!
Features
AlphaBot2 employs a 2-layer structure to provide excellent stability and compatibility.
AlphaBot2-Base (the lower base chassis)
- 5-ch infrared sensor, analogue 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
- N20 micro gear motor, with metal gears, low noise, high accuracy
- Onboard RGB LEDs, true colour lighting
AlphaBot2 for micro:bit (the upper adapter board for the controller)
- micro:bit dedicated connector, for easily connecting with the micro:bit
- MP1584 voltage regulator, provides stable 5V output
- RT9193-33 voltage regulator, provides stable 3.3V voltage to the micro:bit
- TLC1543 AD acquisition chip, allows the micro:bit to use analog sensors
- PCA9685 PWM control chip, I/O expander
- Onboard buzzer to play music
- Dimensions: 110xx x 98mm
