A 3D-printed differential-drive robot that runs on ROS 2 (Foxy) and uses an RPLiDAR A1 to autonomously map and navigate a room via SLAM (Simultaneous Localization And Mapping).
Two 12V planetary-gear DC motors (19.2:1 ratio) drive the wheels through a custom Fusion 360 chassis, closed-loop controlled via an Arduino Mega 2560 running a PID controller against incremental rotary encoders. An NVIDIA Jetson Nano (Ubuntu 20.04, ROS 2 Foxy) handles odometry, the slam_toolbox SLAM pipeline, and Nav2 autonomous navigation, communicating with the Arduino over serial (SerialTransfer library). The design also includes an optional 3D-printed robotic arm and camera mount.
Inspired by James Bruton's ROS SLAM robot build, but designed and built from scratch by the original author.

This orobot.io program is a learning entry point derived from the open-source project above. Full ROS 2 packages, Arduino firmware, Fusion 360 CAD source, and build media are in the source repository — this program packages the design for browsing, printing, and BOM reference; it does not run the full ROS 2/Nav2 stack on orobot.io.
