About Arduinobot

Arduinobot is a 3D-printed learning robot arm by Antonio Brandi: four hobby servos driven by an Arduino, with a complete ROS 2 software stack. Its URDF has five revolute joints (base, shoulder, elbow and a two-link gripper), and one servo drives the gripper. Its printed parts are EEZYbotARM parts: 12 of the 14 STL files carry EEZYbotARM part numbers, and the README credits EEZYbotARM, which is licensed CC BY-NC 4.0, so the hardware is non-commercial. The repo is strongest on software: a URDF/Xacro description with STL meshes, a ros2_control hardware interface, a MoveIt 2 configuration, Arduino firmware (robot_control.ino) and C++ and Python examples, written as companion code for the Udemy course 'Robotics and ROS 2 - Learn by Doing! Manipulators'. It has no priced bill of materials, wiring diagram or printed assembly guide, so building the hardware relies on the course. The software is Apache-2.0.

How to build Arduinobot

5 steps

Steps marked Motari summary condense the linked source; follow the source for exact instructions. Upstream step marks a step taken from the linked guide.

  1. Get the arm structure

    The repo ships only the URDF visual meshes in arduinobot_description/meshes and credits EEZYbotARM in its acknowledgements; no print files or print settings are published. Gather four servos (base, shoulder, elbow, gripper) and an Arduino.

    Motari summaryudemy.com/course/robotics-and-ros-2-learn-by-doing-manipulators

  2. Wire the servos

    Connect base, shoulder, elbow and gripper servos to Arduino pins 8-11 as defined in robot_control.ino.

    Upstream stepgithub.com/AntoBrandi/Arduino-Bot/blob/9ec97b0cec230ac111742...

  3. Flash the firmware

    Load robot_control.ino via the Arduino IDE so the board accepts joint commands over serial.

    Motari summaryudemy.com/course/robotics-and-ros-2-learn-by-doing-manipulators

  4. Build the ROS 2 workspace

    colcon build the packages on ROS 2 Humble (Ubuntu 22.04) or Jazzy (Ubuntu 24.04).

    Upstream stepgithub.com/AntoBrandi/Arduino-Bot/blob/9ec97b0cec230ac111742...

  5. Plan with MoveIt 2

    Launch the real robot with the arduinobot_bringup real_robot.launch.py file, which starts ros2_control, MoveIt 2 and the remote interface.

No reviewed builds of Arduinobot yet.

A build log records the evidence (photos, a video, your repository), what the build cost, how long it took and what you changed. Each one is checked by Motari (until a maintainer claims this page) before it shows here, and reviewed builds count toward the reproducibility score.
