About

We are two founders—one ex-Navy seal, one serial operator—building Virtual Ocean, a “flight simulator” for underwater inspection robots. We need a short, visual demo to show investors how a robot behaves around an offshore wind-turbine base (no heavy physics, just believable motion). ⸻ What You’ll Build (6 calendar weeks, ~60–70 billable hours) 1. Load free models • Find any free / Creative-Commons 3-D model of: • a wind-turbine tower base (cylindrical “steel tube” is fine) • a small underwater robot (BlueROV2 STL is on GitHub) • Import both into Godot 4 (or Unity if you insist). • Make the robot float gently beside the tower base. 2. Give it a simple flight path • Hard-code a spiral route downward around the base (CSV way-points). • Add very basic “float” and “water resistance” forces so motion looks plausible. 3. Add three water speeds & on-screen read-outs • Number keys 1-3 switch between slow / medium / fast water flow (0.3, 0.7, 1.2 knots). • Text overlay shows: current speed, closest distance to the base (metres), battery % (simple fake formula). 4. Make a command-line test • Script (run_demo.bat or .sh) runs the spiral three times—one run per water speed—without opening a graphics window. • Log to results.csv: water speed used, smallest distance, battery left. 5. Create a one-page PDF • Python script reads the CSV and spits out report.pdf with: • bar chart of the “closest distance” for each run (green if ≥ 1.5 m, red if less) • a coloured circle pretending to show inspection coverage (dummy numbers OK). 6. Package it up • Deliver a Windows .exe or a Docker image that rebuilds on Linux. • Include a clear README and a 60-second screen-capture video walkthrough. ⸻ Skills You’ll Need • Godot 4 (preferred) or Unity/Unreal and willing to switch. • Basic physics scripting (forces, drag, buoyancy). • Blender/MeshLab for quick mesh cleanup. • Python (pandas + matplotlib) for the PDF. • Git for version control. (Underwater robotics knowledge is nice but not required.) ⸻ Budget & Payments • Fixed-price cap: US $3 200 (covers up to 80 billable hours). • Milestones: • 40 % paid when water speeds & HUD work (end of week 3). • 40 % paid when report.pdf auto-generates (end of week 5). • 20 % paid on final hand-off (week 6). • Quick, no-drama payments—weekly check-ins over Slack, brief Zoom demo each Friday. ⸻ Ownership & Use of Assets • Work-for-hire: all code and art assigned to Virtual Ocean, Inc. • Use only public-domain or Creative-Commons assets that allow commercial use; list attributions in README. • You may showcase the project in your portfolio after we go public. ⸻ How to Apply (keep it short) 1. Two-sentence bio and one link to a 3-D / physics project you built. 2. Your start date and any time off in the next 8 weeks. 3. A brief note (~3 lines) on how you’d implement the water-current toggle and logging. We’ll shortlist within 72 hours and book a call for a chat. Let’s build the ocean’s first robot test-tank and wow investors!
