Kodro turns robotics learning into one visual loop: Design → Code → Simulate → Prove → Build. Students can assemble robots, program them with Python or blocks, test them in interactive 3D worlds, inspect live sensors and export evidence, all offline-first. Teachers get 24 curriculum lessons plus a lesson creator, while makers can prototype without expensive hardware. No account, cloud connection or AI is required.

Kodro is an offline robot studio for UK Computing, KS1 to KS4. Pupils design a rover, write real code, and run it through simulated worlds, getting pass/fail evidence with telemetry on every run. NEW: Genesis races up to 4 controllers through seeded contracts and proves the winner. Built for reasoning agents: Astra can drive the full loop over MCP, reading code, running it, grading it, iterating, while Kodro holds verdicts no model can fake.
