TableBot · Desktop Cleaning Robot

A group industrial-design project with a working tabletop cleaning prototype. The team developed a drop-and-wipe mechanism and CAD around manufacturing, assembly and disassembly; my focus was technical validation and hardware integration.

01 / OVERVIEW

The project in a minute.

THE OUTCOME

Built and tested a physical prototype, identifying fit, wiring, power and control issues. The production-oriented CAD proposes injection-moulded parts and modular assembly; it is not evidence of mass production.

What supports this? ↓

The challenge: Reduce repetitive tabletop cleaning work through a compact device that can be assembled, maintained and used in a café setting.
My contribution: Prototype testing, wiring, assembly, soldering and power calculations. The report’s contribution statement credits my physical and digital testing, wiring, assembly, soldering, component adaptation, power/load calculations and portfolio communication.
Read this in context: Group course project with a working prototype. Production CAD, compliance research and labels are design work, not certification or commercial deployment. LG-inspired branding is a course design reference, not a claim of employment or an official LG product.

02 / THINKING

The choices behind the result.

Open a chapter to follow the work and the choices made along the way.

01 / ENGINEERING

Turn CAD assumptions into physical checks

I tested the assembled prototype and worked on wiring, soldering and component fit. Physical tests exposed shaft interference, tight tolerances, cable-routing problems, ground clearance and balance issues.

02 / ENGINEERING

Match electronics to the available package and power

The report documents a move from Raspberry Pi to Arduino Uno R3, a 5 V powerbank system and revised components. My contribution included component adaptation and power/load calculations.

03 / DESIGN

Design the product for making and taking apart

The team’s CAD uses a 2 mm wall-thickness target, 2° draft, bottom-up assembly and modular snap-fit features. Manufacturing-oriented CAD remains distinct from the 3D-printed prototype.

03 / EVIDENCE

Results, and what they mean.

Group course project with a working prototype. Production CAD, compliance research and labels are design work, not certification or commercial deployment. LG-inspired branding is a course design reference, not a claim of employment or an official LG product.

Built

Physical prototype

Assembly and operation were tested; it is a separate project from the unbuilt Furrigo concept.
