Work Introduction

The shell used in this work3mm acrylic sheet, through LaserMaker 2.0 Complete structural design and laser cutting processing, assemble into an integrated transparent display shell for easy observation of internal circuit structure. The work is a home ordering interactive device designed for visually impaired people, which does not require a screen and relies on physical braille buttons to complete operations. It is suitable for various home and offline scenarios.

The equipment master control adopts Arduino Uno, equipped with CI-03T Voice broadcasting module. Every time you press a button to select a dish, the system will voice broadcast the dish name and related information. The newly added diet recommendation logic in the work upgrade can make classified recommendations according to the dish attributes, such as automatically recommending low sugar dishes, avoiding high sugar heavy oil dishes, providing users with dietary restrictions such as hypertension and diabetes with a reference to order meals, helping visually impaired people complete the order independently without assistance from others, and improving their autonomy in life.

The shell structure adopts modular assembly design, and the acrylic sheet is slotted and positioned for easy disassembly and debugging of internal electronic components; The transparent shell can visually display the internal wiring and hardware layout, suitable for scientific and technological innovation learning and work display. The entire structure can be directly installed LaserMaker Export the cutting file for easy replication and secondary modification.

Bill of Materials
