For learners

You have an SO-ARM101 arm, or you are about to build one. This section takes you from an unopened box to an arm that picks up a cube on its own.

Read these in order the first time

1. What you need — the arm, the computer, the browser, the desk.
2. Your account — how signing in works and what is on your profile.
3. Connect your arm — USB, Bluetooth, the virtual arm, or somebody else's arm.
4. Calibration — the step that makes the numbers on screen mean something.
5. Your first moves — safety, the emergency stop, and driving a joint by hand.

After that, open the course and start at Module 0.

How the course works

Modules unlock one at a time. Module 0 is open from the start; every other module opens when the one before it is finished. Inside a module you move through numbered steps in the left-hand rail, and a step only opens when the previous one is done.

That sounds strict, and it is deliberate: Module 3 calibrates the arm, and Module 4 assumes the calibration exists. Skipping is how people end up with an arm that reports 45° while pointing somewhere else entirely.

Your progress is stored on the server against your account, so you can start a module on one computer and finish it on another. See Progress and your certificate.

When something goes wrong

Most first-session problems are one of five things: the wrong browser, a motor that never got its ID, a cable on the wrong port, an emergency stop that is still latched, or a calibration that was done in the wrong pose. Troubleshooting lists the exact messages the app shows and what each one means.
