Questions learners ask¶

Can I do the course without a robot?¶

A good part of it, yes. Modules 0, 1 and 7 need no arm at all, and the virtual arm carries you through the simulator work in most of the rest. What it cannot give you is the physical half: assembly, calibration against a real machine, the feel of a grip that is too tight, and the writing module.

Which browser, really?¶

Chrome, Edge, Brave, Opera — anything Chromium, on Windows, macOS or Linux. Safari and Firefox cannot talk to the hardware at all, and neither can any browser on an iPhone or iPad. See Browser support.

Does it work offline?¶

No. The app, the lesson content and your progress all come from the server. Recently visited lessons open from the browser's cache, but treat the platform as online.

Yes, one at a time. The owner enables a remote session and hands out the invitation code; see Driving somebody else's arm. A classroom rotation is covered in the teacher guide.

Can I use my own computer at home and a school computer too?¶

Yes. Progress lives on your account, not on the machine. You will grant the USB permission again on each new computer, and the arm's calibration follows the robot entry on your account.

Do I need my own webcam?¶

Only if you want to. Modules 7 and 8 have a virtual scene built in, and you can switch between it and a real camera at any point.

What do I get at the end?¶

A PDF certificate, once the first seven modules are complete and your subscription is active. Details in Progress and your certificate.

What happens when the subscription ends?¶

The modules lock; nothing is deleted. Your progress, your robots and their calibrations are still there when it is renewed.

Can I go back and redo a module?¶

Any completed module reopens in review mode with every step clickable. Redoing it does not take the completion away.

Why is Module 11 greyed out?¶

The final project is still being built. The eleven modules before it are complete, and the certificate does not depend on it.

Is the neural network in Module 9 real?¶

The workflow is: you collect the images, you label them, you read the curves and you decide when to stop. The training itself is modelled rather than run in your browser, so it behaves the same for everyone. Modules 7 and 8 run genuine OpenCV, and there is a real ArUco detector among the tools.

Can I control the arm from my own code?¶

Not from inside a lesson — there is no code editor in the course. Outside it, the plugin SDK is the supported route, and a plugin you write can be loaded privately into your own browser.

The arm went limp after connecting. Is that a fault?¶

No. The Lab releases the motors so you can pose the arm by hand, which is what calibration needs.
