3D Print Open Source AI Robots

75 stars on GitHub. This open-source customisable underwater drone is a 3D-printable submersible robot designed by Guido and Fabio Schillaci at Humboldt-Universitat zu Berlin. Published as an arXiv preprint, the design enables multiple propeller and thruster configurations for varying research and exploration tasks. Source: https://github.com/guidoschillaci/underwater-drone The drone is built around the 4" watertight enclosure sold by BlueRobotics, providing a waterproof housing for electronics. Thrusters use brushless motors (see note below on component versions); all 18 structural components are 3D-printable and recommended to be printed with solid infill for watertight structural integrity. The modular clamp system allows configuring the drone for different mission profiles — forward-facing cameras, lateral thrusters, ballast placement, or instrument mounting. See Print Files for the full list of 18 printable components. Thruster note: the description references Turnigy Aerodrive DST (DST-700/DST-1200) brushless motors; some BOM links point to the ApisQueen 5060 Waterproof Brushless Underwater Motor instead. Verify which motor you are sourcing before purchase — the two are not the same form factor. Applications include aquatic research, underwater exploration, coral reef monitoring, and educational robotics.

The design is intended for custom electronics integration. The orobot Program code is a reference stub only. To build a controllable version, you will need to design or source your own motor controller and connect it via serial or WiFi. Build Guide 3D models, build instructions, and configuration details: github.com/guidoschillaci/underwater-drone --- Printing This Print All set maps 1:1 to the upstream folder — all 18 structural components, no sim meshes or duplicates. Print in PETG (hydrolysis-stable) with solid / near-100% infill for watertight structural integrity. Quantities (4-thruster configuration) The drone uses 4 thrusters, so thruster and propeller parts repeat: | Part | Qty | Notes | |------|-----|-------| | thrustermain.stl | 4 | One per thruster | | thrustercap.stl | 4 | One per thruster | | thrustermotormount.stl | 4 | One per thruster | | thrusterdst2bluerovadapter.stl | 4 | Motor-to-housing adapter (one per thruster) | | propeller.stl | 4 | One per thruster (or use motor-matched commercial props per BOM) | | clampanteriorsuperior.stl | 1 | Modular clamp | | clampanteriorinferior.stl | 1 | Modular clamp | | clampposteriorsuperior.stl | 1 | Modular clamp | | clampposteriorinferior.stl | 1 | Modular clamp | | posteriorclamp2tubeconnector.stl | 1 | Clamp-to-tube connector | | rearclampconnector.stl | 1 | Rear clamp connector | | adapter90.stl | 1+ | Tube adapter | | adapterroundmale.stl | 1+ | Tube adapter | | adapterroundfemale.stl | 1+ | Tube adapter | | adaptersplit.stl | 1+ | Tube adapter | | stick.stl | 1+ | Structural rod | | ballastcylinder.stl | 1+ | Ballast tube | | ballastcap.stl | 1+ | Ballast cap | Modular by design: the clamp/adapter/ballast system is meant to be reconfigured for different mission profiles (forward camera, lateral thrusters, ballast placement). Print extra adapters, sticks, and ballast cylinders to suit your chosen layout — the counts above are a baseline for a standard 4-thruster build. Motor note: the upstream design targets Turnigy Aerodrive DST motors (hence ); if you source the ApisQueen 5060 motor listed in some BOM links, the motor-mount fit differs — verify before printing the thruster mounts.
