Junctum Protocol & Cloud Menu

Junctum Protocol is the physical proximity and interaction standard that enables mobile rovers (Robulus), stationary machinery (Apparatus), and facilities (Domus) to detect each other nearby and initiate instant menu-driven interactions.

1. Protocol Architecture

1. Physical Presence (BLE): When a robot approaches another device (such as a charging station, automated locker, or base), Bluetooth Low Energy is used to confirm physical presence and identify the target's unique Device ID.
2. Internet-Routed Execution: Once presence is verified, all interaction menus, commands, and payments run seamlessly over the high-speed network.
3. Cloud Menu: Every commercial or service device has a Cloud Menu configured visually in Fabrica (fabrica.juvantia.org). Operators can set up services, prices in euro, and custom operational actions without modifying device firmware.

2. Operational Flow

1. Discovery: A Robulus approaches an Apparatus charging post and detects its BLE service beacon.
2. Menu Retrieval: The operator interface opens the on-screen Cloud Menu:
   • 01. Passport & Tariff
   • 02. Buy Charging Pass (0.50 euro)
3. Instant Settlement: The pilot authorizes the Kernel operation with a passkey.
4. Hardware Action: The station verifies payment, adjusts the charging connector to the required rover height, and initiates power feed.
