Weeks+Shipping: About 1–3 weeks from China (est.). Sold from the Waveshare web store, which ships internationally. The Amazon US listings for the Pi 3 B+, Pi 4 and Arduino kits all show as currently unavailable. Waveshare ↗

Remote control: With the Pi version, a laptop reaches the Pi over SSH or the browser control page on Wi-Fi. The Arduino version uses USB serial for uploading sketches and a Bluetooth serial link for live commands.

Overview

A small round-chassis robot from Waveshare that uses one base board with swappable adapters, so the same chassis works with a Raspberry Pi or an Arduino-compatible board. The Pi version adds a pan-tilt camera and browser control, while the Arduino version adds ultrasonic ranging, an OLED and Bluetooth, which suits a class that wants both paths. Its 5-channel line sensor makes it a good line-following platform. The design dates from around 2017, officially lists only the Pi 3B/3B+/4B, and some bundles are out of stock or discontinued.

Specifications

Category	Wheeled rovers · Ready-made dev rovers
Released	2017
Country	China
Availability	Available
Programmability	Full SDK
Built-in autonomy	Reactive · Responds to its surroundings without a map, such as avoiding obstacles or following a person
LLM support	Possible via SDK · Python on the Pi (or Arduino C++ on the Ar version) could be driven by an LLM, but Waveshare supplies no LLM tooling for AlphaBot2.
MuJoCo simulation	None found · Nothing found.
NVIDIA Isaac simulation	None found · Nothing found.
Gazebo simulation	Community model · Third-party ROS/Gazebo packages with an AlphaBot2 xacro model and world. nestoregon/alphabot2pi_simulation ↗
Best for	Ages 12+ (estimated)
Vision sensors	Camera, Sonar / ultrasonic
Actuators	DC / gear motors
Audio	Speaker
Compute type	Raspberry Pi, Arduino / ESP32 / microcontroller
Remote control	Via SSH / web / bridge
Size	Not published
Drive	2-wheel differential with N20 micro gear motors (1:30, 6 V / 600 RPM), 42 mm rubber wheels
Compute	Raspberry Pi 3B/3B+/4B on the AlphaBot2-Pi adapter board for the Pi version (Pi included only in the bundles). The Arduino version uses an R3 PLUS (ATmega328P, Arduino UNO compatible) on the AlphaBot2-Ar adapter board. Shared AlphaBot2-Base with a TB6612FNG motor driver.
Vision	RPi Camera (B), adjustable focus, on a 2-servo pan-tilt (PCA9685 servo controller) on the Pi version. None on the Arduino version
Lidar	None
Sensors	5-channel IR line tracking (ITR20001/T), 2 IR obstacle sensors (ST188), IR receiver with remote, 5-way joystick, 4 WS2812B RGB LEDs, buzzer. Ultrasonic sensor on the Arduino version only (it does not fit the Pi version). The Arduino adapter adds a 0.96-inch OLED.
Runtime	2 × 14500 Li-ion (not included), charged over USB, runtime not published
Speed	Not published (600 RPM no-load motors with 42 mm wheels give ~1.3 m/s theoretical top speed (est.))
SDK	Python examples on Raspberry Pi OS with browser video and drive control (Bottle web server) for the Pi version. Arduino IDE sketches and a Bluetooth app for iOS and Android for the Arduino version.
