Chapter 2 — Product Introduction

1. Overview

[Image: Side view of the Dobot Coffee Robot — showing A/C vent, advertising screen, cup/lid dispenser, ice maker, touch ordering screen, payment/cup scanner, cup outlet, casters, circulation fan, ambient lighting, coffee machine, syrup/milk/water outlets, refrigerated milk tank, robotic arm, temporary storage station, restocking door, and fixed feet.]

The Dobot Coffee Robot is a fully automatic coffee-making robot. The robotic arm uses a 6-axis collaborative robot (cobot) capable of producing a high-quality, aromatic cup of coffee in as little as 50 seconds. It operates 24 hours a day without human attendance, solving the problems of high labor costs, scarce premium retail space, and inconsistent quality found in traditional coffee shops — providing a brand-new business paradigm for retail automation.

2. System Overview

[Image: Front view of the Dobot Coffee Robot — showing circulation fan, cup/lid dispenser, ice maker, robotic arm, touch ordering screen, mobile feet, surveillance camera, advertising screen, syrup machine, coffee machine, refrigerated milk tank, cup outlet, and fixed feet.]

The Dobot Coffee Robot consists of eight main systems and modules:

1. Cup & Lid Dispensing System
2. Coffee Machine Module
3. Fresh Milk Supply System
4. Syrup Supply System
5. Purified Water Supply System
6. Waste Recovery System

3. Cup & Lid Dispensing System

[Image: Front view of the cup/lid dispenser — showing lid buckets, paper cup bucket, iced cup bucket, paper cup dispensing sensor, iced cup dispensing sensor, and fixed feet.]

A dispensing sensor is installed at the rear bottom of each cup dispenser to detect whether a cup has been successfully dispensed. If no cup is detected after dispensing, the system automatically alerts a dispensing failure and simultaneously issues a re-dispensing command.

The lid dispenser contains two lid dispensers, each with a lid bucket that can store 70–80 disposable lids. The total number of lids matches the total number of cups. A sensor at the bottom of each lid bucket detects low-lid conditions. When the lid count drops below a certain threshold, the system automatically alerts operational staff to replenish lids.

The dispenser feet are fixed to the equipment platform to prevent movement during transportation.

4. Coffee Machine Module

11. If the power cord is damaged, it must be replaced by qualified service personnel only.

7. Syrup Supply System

The syrup supply system consists of a syrup storage module and a dispensing module. The storage module holds 4 syrup lines, each equipped with a weight sensor to monitor syrup usage. When syrup drops below a preset threshold, the system automatically alerts for replenishment.

The storage module includes an observation window for manual monitoring of syrup levels at any time.

[Image: Syrup storage module and dispensing module.]

The dispensing module is made of stainless steel and includes combined outlets for syrup, purified water, and fresh milk. A drain tray and drain connector are located below the outlet. During syrup cleaning, hot water flows through the drain tray and connector into the waste water tank.

8. Water Supply System

The water supply system is located at the bottom of the work station and provides purified water to the coffee machine, ice maker, water lines, and cleaning mechanisms. It consists of a transfer water tank and water supply barrels.

[Image: Water supply system — transfer tank bracket, water outlet, transfer tank, solenoid valve, pump, and water supply barrels.]

The bottom of the work station can hold four 19 L water supply barrels. When fully stocked, they can supply enough water for over 200 cups of coffee. The barrels supply water to the transfer tank via a pump in sequence. When one barrel is empty, the system automatically switches to the next. When all barrels are empty, the system triggers an alarm.

The transfer tank holds 5 L of purified water and has high/low level sensors. When the water level is too low, the system automatically pumps water from the supply barrels. The tank has multiple outlets to provide stable purified water to the coffee machine and ice maker.

9. Waste Recovery System

[Image: Waste recovery system — waste water tray, syrup waste connector, coffee machine waste connector, waste tray drain connector, ice maker waste connector, waste water/slag barrel, and slag barrel slide rail.]

Waste includes coffee grounds and waste water. Coffee grounds from the coffee machine fall through a chute at the bottom into the waste slag barrel automatically.

The waste water barrel has a capacity of 50 L, enough for at least one day of waste. It is divided into a slag drain tray (to separate solids from liquids) and the waste water barrel.

The slag barrel slide rail is made of 304 stainless steel. When the waste barrel is full, it can be pulled out of the robot via the slide rail.

2. Use purified water in barrels — avoid mineral water. Add a water purifier if using tap water.
3. Regularly use dedicated descaling tablets to clean internal scale from the coffee machine.
4. Automatically clean the milk frother pipe opening daily to prevent blockage.

Chapter 6 — Troubleshooting

#	Fault	Possible Causes	Solution
1	Cup dispenser jammed	Cup rim thickness > 3.5 mm or deformed; cups not round	Replace with compliant cups
