| Activity | Frequency | What to Do |
|----------|-----------|------------|
| Visual inspection | Every 6 months (or after major shutdown) | Look for corrosion on connectors, loose screws, dust accumulation. |
| Connector cleaning | Annually | Use contact‑cleaner spray on motor/encoder plugs; re‑torque to 0.5 Nm. |
| Firmware backup | After each successful update | Export the current EEPROM image via controller.backup_eeprom(). |
| Thermal check | Quarterly | Verify that the controller surface temperature stays < 55 °C under typical load. |
| Calibration | Yearly (or after mechanical rebuild) | Run the Zero‑Offset routine for each encoder; store the new offsets. |
| Backup power test | Every 12 months (if using UPS) | Simulate a power loss; ensure the controller shuts down gracefully and restarts without error. |
| Challenge | Risk | JUFE‑384 Mitigation | |-----------|------|---------------------| | Heat dissipation in high‑compute mode | Throttling, reduced lifespan | Copper‑core heat spreader + active fan optional; dynamic power scaling. | | Supply‑chain volatility for modules | Delayed shipments | Modular design allows swapping alternative vendors (e.g., Bluetooth vs. Thread). | | Developer learning curve for edge AI | Low adoption | Extensive tutorials, sample code, and a thriving Discord community. | | Regulatory compliance (medical, automotive) | Certification costs | Pre‑certified reference designs (ISO 13485, ISO 26262). |

# Set motion parameters for each axis
for axis in range(1, 5):
controller.set_velocity(axis, 5000) # counts/s

| Function | Description |
|----------|-------------|
| set_velocity(axis, vel) | Max velocity (counts / s) for the specified axis. |
| set_acceleration(axis, acc) | Max acceleration (counts / s²). |
| move_absolute(pos_list) | Synchronous move of all axes to absolute positions. |
| wait_done() | Blocks until all axes report in‑position and motion complete. |
| read_position() | Returns a list of current encoder counts for each axis. |
JUFE-384 shows how a terse label can both conceal and reveal. Whether read as administrative shorthand, technical lineage, or narrative spur, the code invites curiosity: what systems produced it, what lives it touches, and what stories it quietly indexes. | Challenge | Risk | JUFE‑384 Mitigation |

| Pain Point | Traditional Solution | JUFE‑384 Advantage | |------------|----------------------|--------------------| | Fragmented ecosystems – Multiple proprietary SDKs for wearables, sensors, and edge devices. | Develop separate apps per device; costly integration. | One unified SDK + Open‑Source API that abstracts hardware differences. | | Latency & bandwidth – Cloud‑only AI inference leads to lag and privacy concerns. | Rely on distant servers; data throttling. | On‑device AI (up to 384 TOPS) with edge‑first processing. | | Security nightmares – Firmware updates, data leakage, device hijacking. | Patch cycles, OTA updates, limited encryption. | Secure Enclave (ARM TrustZone + custom TPM) + zero‑trust OTA. | | Scalability – Scaling prototypes to production often requires redesign. | Manual redesign, new PCB, new firmware. | Modular board system – swap modules (BLE, LTE‑Cat‑M, Vision) without redesign. |
