Before your first build

Do I need a robotics kit?

No. Start with a supported online simulator. Physical builds are optional.

No. Start in a supported online simulator. Hardware is optional.

Can I use my phone?

Yes. You can read every project guide and concept explanation on your smartphone. When you are ready to code and run the simulator, a laptop, desktop, or tablet works best.

Do I need an account?

No sign-in or account is needed. All 24 flagship projects, simulators, and guides are 100% free and open to explore right away.
