50 Hz MuJoCo WASM ONNX Runtime Web Pollen Microduck & Open Duck Mini Feetech HD-1910 / HL-2915 / STS3215 Upload & Test Custom .ONNX

Zero-install 3D physics apartment and community locomotion hub where open-source bipedal robot ducks run real neural policies in the browser at 50 Hz, navigate obstacles and carpets, kick soccer balls, dock for charging, and hot-swap .ONNX skills in 1 click.

Live .ONNX Policy Suite ([1, 61] -> [1, 14]): BEST_alpha_walking.onnx, roulade.onnx (forward somersault & recovery), alpha_ground_pick.onnx, ball_kick_left/right.onnx, happy-hop (backlash-trained), single-leg balance, and SHA-256 verified kissqy R17-V167 6x Feetech HD-1910 suite + drag-and-drop custom .onnx benchmarking.
Floor 2 AI Autonomy Brains: quackd LLM mission orchestrator, DuckBuddy voice/vision daemon, duck-echo BPM rhythm & voice guard, duckmind pet lifecycle, quackback MCP coder assistant, and smart low-battery auto-docking.

๐Ÿš€ Scientific SaaS & Reinforcement Learning Labs

ecoli.bio - Metabolic Flux SaaS

Interactive scientific platform simulating E. coli central carbon metabolism (genome-scale model iJO1366). Powered by Cloudflare Workers, Durable Objects, D1, WebAssembly (HiGHS LP solver), PixiJS, and Gemini AI.

STEPS - 200 Hz 3D Physics & PPO Locomotion Lab

Real-time 3D physics simulation (Symplectic Euler + XPBD + Coulomb friction) where articulated multi-legged walkers learn locomotion from scratch in the browser via PPO Actor-Critic and SEP-CMA-ES.

ngzip-llm - Zero-Retraining LLM Compression

Dynamic Neuron Prosthesis and LECAP gate pruning (25%-50% sparsity) with low-rank residual compensation on Llama-3.2-1B (PyTorch / Hugging Face on RunPod GPUs).

Neural-Futsal - Multi-Agent RL

2.5D tactical futsal simulator where 3v3 teams of autonomous Deep MLP agents execute coordinated passes, dribbles, and shots in real time using vanilla JS, Canvas, and Web Workers.

๐Ÿค Open Source Contributions

pollen-robotics/microduck-simulator (PR #13): Cold-boot acceleration via build-time gzip_static compression for MuJoCo & ONNX Runtime WebAssembly bundles (25.15 MB -> 6.48 MB), parallel ONNX/GLB asset prefetching, and kinematics fetch deduplication.
joeynyc/awesome-microduck: Featured community simulator & .ONNX policy testing hub (DuckSpace.org) for the open-source Microduck robotics ecosystem.
