3D-printed shell parts and electronic components, picking and matching each one.
Mainboard, screen and LED strip positioned, ready for soldering.
Body structure taking shape, confirming each part's position.
Soldering screen, LED strip and wiring with the iron — the most patience-testing step. Joints must be solid, not cold.
Burning ESP32-S3 firmware and AI dialogue program, making the hardware "alive".
Whole robot comes together — a proper WALL-E in front of you.
