Arduinobot

Arduinobot is an open-source, 3D-printed learning robot arm by Antonio Brandi, built around four hobby servos driven by an Arduino and a complete ROS 2 software stack. The mechanical design derives from the popular EEZYbotARM, and the arm exposes five revolute joints (base, shoulder, elbow and a two-link gripper) with the gripper actuated as a single servo. The strength of the project is software, not hardware documentation: the repo ships a full URDF/Xacro description with STL meshes, ros2_control hardware interface, a MoveIt 2 configuration, Arduino firmware (robot_control.ino) and extensive C++/Python example packages, and it is the companion code for the Udemy course 'Robotics and ROS 2 - Learn by Doing! Manipulators'. There is no priced itemized bill of materials, wiring diagram or printed assembly guide in the repository, so hardware reproduction still relies on the upstream EEZYbotARM and the course; however, the README, firmware and URDF identify the Arduino controller, four servo axes and printable mesh set.

What you get

• A standardized, machine-readable robot schema derived from the source repo.
• A primary assembly 3D asset is available from arduinobot_description/urdf/arduinobot.urdf.xacro.
• Source-backed bill-of-materials evidence is linked with per-part provenance where available. Prices marked estimated are not yet verified against a vendor.
• A transparent reproducibility score so buildability is a sortable, first-class property.
• Cross-links to the source repo, datasets, models, and forks.
