I’m looking for a complete CAD model of an educational robot aimed squarely at teenagers (13–18 years old). The core learning activity it will support is still open for discussion, so I want a design that stays flexible enough to accept different sensor packs, micro-controller boards (Arduino, Raspberry Pi, etc.), and small add-ons as we refine the curriculum. What I need from you is a clean, manufacturable mechanical design—no electronics layout yet—delivered as fully editable 3-D files plus ready-to-print exports. Please work in SolidWorks, Fusion 360, or a comparable professional tool so we can collaborate smoothly and hand off to fabrication without extra conversions. Deliverables • Native CAD files of every part and the full assembly • STEP and STL exports suitable for 3-D printing or light CNC machining • An exploded assembly drawing with a concise bill of materials • A short motion study or animation that demonstrates the basic articulation Acceptance criteria • Every component fits a 300 × 300 × 300 mm build volume (or smaller) • Parts rely on readily available fasteners and hand-tool assembly • Design leaves reserved space for a battery pack, controller board, and two standard sensor modules If you’re ready to bring a teen-friendly robot to life in CAD, I’d love to see recent mechanical work you’ve done—especially anything that moved, rolled, or taught someone something new.
