Mirai — AI-Powered Robot Arm Simulator

Mirai (ミライ, "Future") is a browser-first robotics platform that removes every barrier between an idea and a working robot arm — no installation, no coding required. The Problem: Robotics has a steep entry barrier. Expensive hardware, complex toolchains, and specialized programming knowledge stop most people before they start. The Solution: Users design a custom 3D robot arm using a segment editor with live BOM pricing, then describe a task in plain English. Gemini AI generates a structured motion plan grounded against the actual arm geometry and scene. A deterministic verifier checks safety and reachability before any simulation runs. The arm then executes the verified plan at 60fps using Rapier WASM physics in the browser. Key Features: - Natural language to motion plan via Gemini 2.5 Flash with auto pre-flight validation - 60fps in-browser simulation (Rapier WASM) cross-validated against MuJoCo on the server - Servo lifespan prediction and divergence analysis - Community task library with 11 seeded tasks and famous robot preloads (Boston Dynamics, Tesla Optimus, Toyota Research) - One-click export: Arduino .ino, Python .py, URDF, BOM CSV, SHA-256 signed ZIP bundle Mirai bridges idea and real hardware. Any person with a browser and a $300 budget can design, simulate, validate, and build a functional robot arm in minutes.
