Detection of Nitrate ions using Capillary Zone Electrophoresis

I designed a Capillary Zone Electrophoresis (CZE)–based nitrate sensing system for environmental water monitoring, focusing on creating a low-cost, portable, and reliable analytical solution. I applied the principles of electrophoresis and electroosmotic flow to design a system consisting of a fused-silica capillary, a high-voltage power supply, and an integrated optical detection unit using a UV-LED and photodiode for indirect nitrate measurement. I analysed and optimised key parameters such as buffer composition, sample preparation, applied voltage, and separation efficiency to achieve accurate and reproducible results. I also explored system miniaturisation and field deployment by developing a modular design with portable power integration and microfluidic concepts, enabling real-time, on-site water quality monitoring. This project demonstrates my ability to integrate analytical chemistry, electronics, and engineering design to develop a practical and scalable sensing system.

Industrial SCARA Robot

I am currently designing and developing an industrial SCARA robot, with the end goal of accurately picking and placing a 1 kg payload to a specified location. The project involves full mechanical design in SolidWorks, alongside hands-on manufacturing and system integration. I have researched and developed the robot architecture, selecting appropriate components and refining the design through iterative prototyping. Initial parts were produced using 3D printing and laser cutting to enable rapid prototyping and testing before transitioning to more robust materials such as aluminium for final components. Manufacturing has involved the use of workshop machinery including the lathe, milling machine, waterjet cutter, and laser cutter. This ongoing project demonstrates my ability to take a concept from design through to physical implementation, combining CAD, fabrication, and practical engineering skills.

Pixy Robot

I developed a vision-based autonomous robot capable of tracking and following a target object using a Pixy CMUcam5 image sensor. The system utilizes color-based object recognition, where the camera is trained to detect a specific object (yellow), enabling the robot to dynamically adjust its motion, moving forward when the target is at a distance and reversing when it is too close. The robot is powered by a 12V battery system and controlled via an Arduino Mega interfaced with a Dual VNH5019 motor driver to drive two DC motors, allowing precise bidirectional movement and turning. The project involved integrating hardware and software, including developing control logic for object tracking, distance-based response behavior, and troubleshooting system performance. This project demonstrates my ability to combine embedded systems, computer vision, and mechanical design to create an autonomous robotic system with real-time environmental interaction.

PLC-Based Object Detection System using Beckhoff and TwinCAT

I developed an industrial automation system by interfacing a retroreflective photoelectric sensor with a Beckhoff PLC, using TwinCAT for programming and control. The project involved configuring and wiring the sensor within a 24V control system, integrating it with Beckhoff I/O modules, and ensuring reliable signal acquisition for object detection. I programmed the PLC in TwinCAT to process the sensor input and implement control logic, enabling real-time detection and response suitable for industrial applications such as part sensing and position verification. The setup included proper power distribution, terminal wiring, and system organisation on a DIN rail, reflecting standard industrial practices. This project demonstrates my ability to work with PLC-based control systems, industrial sensors, and structured automation software to develop reliable and scalable control solutions.
