How it works
The loop is the product.
MyRoboBrick collapses build → code → run into a single short loop. Here is every step, in order, with what actually happens under the hood.
STEP 01
Connect the hub
Pair a SPIKE Prime hub over Bluetooth. The app introspects what is attached: motor types, sensor models, battery level, firmware version, and signal strength.
- Bluetooth Low Energy pairing in seconds
- Auto-detect motors, color, distance, and force sensors
- Surface battery, firmware, and signal as live state
- Disconnect / reconnect tolerated mid-skill

STEP 02
Save the build
Capture a photo of the actual robot, sketch a port map, and write a short note about what it is supposed to do. This is the context the assistant works from.
- Photos: top, side, arm detail
- Port map: roles per port, not just types
- Intent notes: "follows tape and stops at red"
- Build copies stay on the iPhone; AI requests share context, and optional feedback can include photos

STEP 03
Create skills
Ask in plain English. The assistant drafts MicroPython, you read and tweak it, then save the working version into a library you can re-use across builds.
- Plain-English prompt to MicroPython
- Skills are diff-friendly text files, not blocks
- Versions auto-saved on each successful run
- Library is per-build, sharable as a folder

STEP 04
Talk to the robot
Run a skill by voice — "follow the line" — and live sensor state shapes the next bounded action. Motor timing stays deterministic on the hub.
- Voice intent → skill selection
- Live telemetry visible during the run
- Bounded actions: clear stop conditions
- Failures are explained in plain language
