Common questions

Free for everyone, for good: all 409 lessons, the 3D simulator, the games and competitions, class codes, and the live view of your class during the lesson. Students never pay and need no account.

Paid, with a Teacher plan or a School plan: the progress board, mark book and certificates; assignments, due dates and module locks; answer keys, lesson plans, worksheets and slides; and tasks you write yourself. The School plan adds sign-in with the school's Google or Microsoft accounts, homework and marking outside the lesson, a department view and the data protection pack.

Sold separately: the BugBot robot, for running the same programs on real hardware. Every teacher gets 30 days of everything free, starting with their first class.

Yes, and that is the point. The whole course runs in the simulator in a browser, so a whole class can learn robotics with no hardware at all. The same programs upload directly to a real BugBot if you add one later.

The Teacher plan is £149 a year, paid by card, and the School plan £595 for a first year and £795 after, ex VAT, with £495 for a founding school's first year if they commit before 31 December 2026. Every teacher gets 30 days of everything free. Schools pay on invoice with a purchase order, or by card, and trusts get a discount for three schools or more. Email info@bugbotlab.com for a proforma invoice within one working day.

Usually nothing. It runs in any modern browser with no installation, and students need no accounts. If you want to allow the sites through a filter, the addresses are on the For IT teams page, along with the data map, the privacy notice and a pre-filled impact assessment.

We are not taking orders yet. The boards are designed and not yet in production, and the waitlist is first in the queue and the first to hear a date and a price. The robot is an add-on to the course, so nothing about your lessons depends on waiting for it.

Students join with a class code, so we hold no email addresses and no dates of birth. Schools that want progress tracked choose what identifies a student, and it never has to be an email address. Class data is stored in London, deleted when you ask and automatically after twelve months unused. Every school gets a signed data processing agreement. Nothing is sold, and nothing is used to train AI models.
Who we are
