Note: Raspberry Pi is NOT included.OverviewThis AlphaBot2 robot kit is designed to use with Raspberry Pi 3 Model B (not included). It features rich common robot functions including line tracking, obstacle avoiding, Bluetooth/infrared/WiFi remote control, video monitoring, 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, you're 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: 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 N20 micro gear motor, with metal gears, low noise, high accuracy Onboard RGB LEDs, true color lighting, pretty cool AlphaBot2-Pi, the upper adapter board for controller: LM2596 voltage regulator, provides the Pi with stable 5V power TLC1543 AD acquisition chip, allows the Pi to use analog sensors PCA9685 servo controller, make it more smoothly to rotate the pan head CP2102 UART converter, easy for controlling the Pi via UART What's on the AlphaBot2-Base AlphaBot2 control interface: for connecting sorts of controller adapter board Ultrasonic module interface Obstacle avoiding indicators Omni-direction wheel ST188: reflective infrared photoelectric sensor, for obstacle avoiding ITR20001/T: reflective infrared photoelectric sensor, for line tracking Potentiometer for adjusting obstacle avoiding range TB6612FNG dual H-bridge motor driver LM393 voltage comparator N20 micro gear motor reduction rate 1:30, 6V/600RPM Rubber wheels diameter 42mm, width 19mm Power switch Battery holder: supports 14500 batteries WS2812B: true color RGB LEDs Power indicator What's on the AlphaBot2-Pi AlphaBot2 control interface: for connecting AlphaBot2-Base Raspberry Pi interface: for connecting Raspberry Pi 3 Model B Servo interface USB TO UART: easy for controlling the Pi via UART LM2596: 5V voltage regulator TLC1543: 10-bit AD acquisition chip, allows the Pi to use analog sensors PCA9685: servo controller, make it more smoothly to rotate the pan head CP2102: USB TO UART converter Joystick IR receiver Buzzer Photos AlphaBot2-Pi top view AlphaBot2-Pi bottom view AlphaBot2-Base top view AlphaBot2-Base bottom view AlphaBot2-Pi robot front view AlphaBot2-Pi robot back view AlphaBot2-Pi robot side view AlphaBot2-Pi robot disassembly AlphaBot2-Pi robot side view AlphaBot2-Pi robot side view AlphaBot2-Pi robot back view AlphaBot2-Pi robot bottom view Examples AlphaBot2 multi robots line following AlphaBot2-Pi robot obstacle avoiding AlphaBot2-Pi robot RGB LED remote control AlphaBot2-Pi robot video monitor AlphaBot2-Pi robot Bluetooth control Note: photos are FOR REFERENCE ONLY, the other boards/modules/accessories are NOT included in the price.DimensionsDevelopment ResourcesWiki : www.waveshare.com/wiki/AlphaBot2-PiPackage Content: Weight: 0.381 kg AlphaBot2-Pi Acc Pack Note: this product requires two 14500 batteries to work, which are NOT included and should be purchased separately.
