Arduinobot is an open-source 3D-printed robot arm powered by ROS 2, designed as an accessible learning platform for robotics and manipulation. Created by Antonio Brandi, it is the companion hardware to the "Robotics and ROS 2 - Learn by Doing! Manipulators" online course.

The arm is built entirely from 14 3D-printable parts: a basement and base plate forming the base structure, a vertical drive arm and forward drive arm for the main two links, a horizontal arm for the third joint, a link and triangular link for intermediate connections, a round plate and servo plate for the wrist assembly, a pi_camera mount for adding a Raspberry Pi camera, and a parallel claw gripper with left finger, right finger, and claw support.
Control uses Arduino for low-level servo actuation via an Arduino firmware script (robot_control.ino), while ROS 2 handles high-level planning, motion execution, and simulation. A full Gazebo simulation environment mirrors the physical robot, enabling development and testing without hardware. The accompanying course covers URDF modeling, MoveIt2 motion planning, custom control interfaces, pick-and-place tasks, and computer vision integration.
The design prioritizes simplicity and low cost, making it practical for students learning the full robotics stack from hardware assembly through ROS 2 programming.
