Introduction

Imagine a world without milk. No latté, no cappuccino, no croissants. No fresh milk, yoghurt, crème fraiche or butter. No cheese – no mozzarella, brie, pecorino or Stilton, no feta, chèvre, cheddar or Bavarian bleu. No ice cream, no pizza. How could we live a civilized life without milk?

Your Task

Design of an user-interface for a robotic milking station

Your group –

an enterprise for user-interface design –

was engaged from a world leading

producer of farming machinery

to design the user-interface

for a brand-new robotic milking station.

The Technical Specifications

Hardware:

• 1 x Touch-Panel for local interaction (15” on the machine)

• 1 x mobile device for mobile access to Information (Tablet or SmartPhone)

Specifications

Two main components:– Milking robot– Milk tanks

Identified user groups :– Farmer– Service technician– Milk collector

Basic functions: – Status of the milking robot („Milking in Process“, „Waiting for Cow“, „Error“,

„Cleaning in Process“)– Status of the milk tanks (Amount of milk in the tanks, Cooling temperature)– Daily, weekly and monthly overview about the milk production– Timer for start and stop the milking robot– Error log– Adjustment of machine parameters (e.g. Cooling temperature, vacuum)– User authorization– Automatic cleaning of the milking robot– Pump-up the milk from the tanks
