Robot Barista Store Operation App

• Operation app for a store where a collaborative robot brews the coffee, driven from a touchscreen
• Users: store staff on shift, plus technicians handling installation and service
• End-to-end path: kiosk order received → queued → brewing command sent to the robot → per-cup progress shown → completion recorded
• Four bottom tabs (Main, Open | Close, Settings, Alarms) plus a separate admin screen
• Fixed full-screen layout for touch-only operation, with no keyboard required

• Robot responds only to fixed signals → orders cannot be passed through as-is, they must become brewing units
• Store staff cannot operate robot controls directly → everything on site has to happen on the store screen
• Dropped connections, restarts and aborted extractions occur during trading hours → order state must survive them
• Beans and the knock box are refilled and emptied by hand → the screen has to flag replacement first
• Opening and closing checks drift from person to person → the screen has to fix the order

• Two intake paths: automatic kiosk orders and manual orders placed by staff
• Manual order built from caffeinated or decaf, single or double shot, and quantity
• Kiosk link toggled on and off during trading hours → manual operation continues while the kiosk is serviced
• Matching menu on the latest waiting order merged up to 99 cups → keeps the queue from filling with the same drink
• Queue showing up to 15 waiting and 5 completed orders, with per-cup progress alongside
• Per-order cancellation for waiting items, plus a full queue reset when orders pile up
• Continuous extraction without a set quantity, and an immediate stop

Order flow

• Kiosk or manual entry → queued → brewing command to the robot → per-cup progress updated → completion or abort recorded

Screens

• Main: order queue and order controls
• Open | Close: opening and closing checks with equipment status
• Settings: consumable usage counts and replacement thresholds
• Alarms: error history
• Admin: equipment signals and connection settings for service work

• Command sent → receipt confirmed → command cleared → completion signal exchanged → no duplicate brewing, no lost commands
• On restart, waiting orders restored, and any job the robot was still reporting on finished first before normal operation resumes
• Dropped connection retried automatically, with the drop written to the alarm history
• Counts for grinders, knock box and espresso machine raised at the start of every cup, with a full-screen notice at the threshold
• Errors turned into coded guidance on a full-screen notice that stays until cleared → empty cup, missing portafilter, collision stop, emergency stop, lost connection
• Opening and closing checks laid out over eight illustrated steps, with portafilter, knock box, conveyor sensor, servo and emergency stop states shown beside them
• Closing posture blocked while brewing → no collision from moving the arm mid-job
• Numbers and addresses entered on an on-screen keypad → suits store installations without a keyboard
• Equipment signal settings read back from the robot on connection → screen values never drift from the equipment

• Staff open, run and close the store from the display alone, never through robot controls
• Kiosk orders reach the robot without passing through anyone's hands
• Errors during service come with their cause and remedy on screen, and the past history stays available
• Bean and knock box replacement tracked by usage count rather than by feel
• Waiting orders survive restarts and dropped connections, so service continues uninterrupted
• Technicians adjust equipment signals and connection settings on site from the screen
