Code robots in an offline Python learning simulator
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.
Hey Product Hunt! I’m Vaibhav, the maker of Kodro.
I built Kodro because beginner robot programming can feel unnecessarily inaccessible: physical kits cost money, setup is fragile, and many simulators are built for professional robotics workflows rather than pupils or first-time coders.
Kodro is a free, open-source and offline-first place to design a robot, write Python, and watch it attempt a task in a visual world.
You can:
• Learn with 24 guided coding lessons, hints and worked solutions
• Build a rover from hobby parts and see how choices affect range, speed and stopping distance
• Program through a beginner-friendly Python subset or blocks
• Test ideas in a room, city, deserts, underwater environments, Mars and space
• Create and share your own class lessons with deterministic grading
The important constraint is that the core experience works without an account, API key or internet connection. Optional AI help can run locally through Ollama, while a deterministic offline fallback remains available when no model is installed.
Kodro is an MSc research project from the University of Liverpool, and I’d really value feedback from educators, parents, makers and developers:
What would make a robot-coding simulator genuinely useful in your classroom, club or learning journey?

Who hunted Kodro?
Kodro was hunted by Vaibhav Lalwani. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
