We built a desktop companion robot that is powered by Arduino UNO Q. Project is open source: source code, 3D printable files and assembly instructions are available at Arduino Project Hub.Robot is equipped with camera, distance sensor, buzzer, moves head and arms with 3 servo motors and has an animated display. It can recognise objects and respond to it. We build it with idea this should be fun project people can 3D print and build at home themself.

Could you build this?
No This is a physical hardware project involving 3D-printable structural mechanics, servos, microcontrollers (Arduino UNO), sensors, and physical electronic prototyping that cannot be built through vibe coding alone.
What it would actually take: Requires CAD design and mechanical engineering for tolerances, 3D printing, circuit breadboarding/PCB design, power distribution for servo current spikes, and embedded C++ firmware running on an Arduino Uno or equivalent microcontroller interfacing with distance sensors and PWM servo lines.
