OverviewThis AlphaBot2 robot kit is designed to use with an Arduino 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, no soldering, no wiring. After a few minutes spent on hardware assembing, youre almost there, our open source demo codes is ready to help you get started fast.AlphaBot2 FeaturesAlphaBot2 employs a 2-layer structure to provide excellent stability and compatibility.AlphaBot2-Base, the lower base chassis:1. 5-ch infrared sensor, analog output, combined with PID algorithm, stable line tracking2. Onboard modules like line tracking, obstacle avoiding, needs no messy wiring3. TB6612FNG dual H-bridge motor driver, compared with L298P, its more efficient, more compact, and less heating4. N20 micro gear motor, with metal gears, low noise, high accuracy5. Onboard RGB LEDs, true color lighting, pretty coolAlphaBot2-Ar, the upper adapter board for controller:1. Onboard Arduino interface, into which Arduino controller can be directly plugged2. 0.96inch 128x64 yellow/blue dual color OLED3. TLC1543 AD acquisition chip4. PC8574 I/O expander, avoid I/O shortage5. Xbee connector, for connecting dual-mode Bluetooth modulePackage Contents1. AlphaBot2-Ar (adapter board) x12. AlphaBot2-Base (base chassis) x13.
