Selected projects

Robotics, flight, simulation, and mechanical design.

01
Robotics / Simulation

Colour-sorting robot

An e-puck robot project in Webots, combining camera-based ball recognition with motion control and cliff detection.

My contribution

Camera image analysis and the sorting algorithm: interpreting visual input and deciding how the robot should respond to each ball colour.

Team integration

The vision and sorting logic work alongside a teammate's motion control, state machine, cliff detection, and proportional control.

02
Mechanical / Design

Three-stage reduction gearbox

A compact gearbox design project exploring gear arrangements, shaft connections, and a laser-cut acrylic enclosure.

Design decisions

Comparing simple, stacked, reverted, and compound layouts using a Pugh chart to guide concept selection.

Packaging & manufacture

Working within compact dimensions while considering shaft geometry, bearings, keyed connections, and a 6 mm acrylic enclosure.

03
UAV / System integration

VTOL drone build

Built and integrated a vertical take-off and landing drone from scratch during 48 hours of hands-on UAV training.

Hands-on work

Airframe assembly, electronics wiring, soldering, calibration, testing, and troubleshooting to bring the mechanical and electronic systems together.

Flight-control learning

Practical exposure to Pixhawk/PX4 configuration, flight-control hardware, VTOL aerodynamics, and transition-control concepts. Training completed with Under Control, July–August 2026.

04
Simulation / Kinematics

MATLAB projectile-motion simulator

A three-person ENGG100 project calculating launch conditions to reach a target while clearing a building obstruction.

How the simulation works

Searches launch angles from 1° to 89° and calculates the required initial velocity. It checks 20 points across the building width with a 0.1 m clearance margin, then plots the first accepted trajectory.

Team contribution

Co-developed the simulation and project documentation in a team of three, with equal contributions recorded. The tool accepts the launch position and building geometry and reports when no valid solution is found.

05
Mechanical / Manufacturing

Mechanical catapult

A design and manufacturing project turning Fusion 360 components and technical drawings into an assembled physical mechanism.

Design & fabrication

Developed components, technical drawings, and an exploded assembly in Fusion 360. Manufacturing combined laser cutting, 3D printing, and manual lathe and grinder work.

Assembly & iteration

Worked through component fit and tolerance problems during assembly and testing as part of the MMMB203 team project.

Beyond the coursework

Curious about how
things work.
Driven to build them.

I'm a mechatronics engineering student at UOWD, interested in building systems that connect physical mechanisms with intelligent control.

My focus is on robotics and automation, with a growing interest in sustainability and engineering solutions relevant to Oman and the wider region.

I enjoy the full path from an initial idea to a practical design: exploring concepts, making decisions, and bringing separate parts together into a working system.
