Robotics - CAD - Prototype log

Designing practical ideas into working prototypes.

E-Creates is my portfolio of robotics, product design, electronics, software, and 3D printed builds, developed through hands-on experimentation and engineering study.

Case study

Buddi

A compact desk robot project showing CAD design, embedded control, expressive interaction, and iterative prototyping in one build.

Buddi demonstrates practical engineering across enclosure design, embedded electronics, interaction design, and build iteration. It is the clearest example of the kind of robotics work I want to keep developing.

What I can do

Engineering support from idea to prototype.

I combine CAD, electronics, robotics, software, and 3D printing to turn early concepts into testable physical builds.

Robotics Prototypes

Small robotic platforms, mechanisms, expressive devices, and proof-of-concept builds.

CAD and Mechanical Design

Parts, enclosures, brackets, mounts, mechanisms, and designs prepared for fabrication.

Electronics Prototyping

Microcontroller projects, sensor integration, wiring plans, test circuits, and iteration support.

Software Development

Embedded logic, control behaviour, web tools, project interfaces, and build documentation.

Skills and tools

Specific proof of capability.

The core skills are supported by practical tools, build processes, and hands-on testing.

CAD Electrical prototyping Robotics Mechanical designs Software development
CAD / Design Fusion 360, mechanical assemblies, print-ready parts
Electronics ESP32, Arduino-style prototyping, soldering, sensor wiring
Fabrication FDM 3D printing, tolerancing, fit checks, iteration cycles
Software Embedded logic, Python/C-style development, web interfaces

Freelance direction

Services for makers, students, and early-stage ideas.

Alongside employment-focused portfolio work, I can support small custom projects that need CAD, prototyping, 3D printing, or robotics thinking.
