Hi, I'm Mel J

Mechatronics engineer in Melbourne. I work across robotics, sensor fusion, control systems and automotive electronics. I like being close to the hardware: building it, testing it and iterating it to run efficiently.

M.Eng Mechatronics Engineering (Manufacturing), University of Melbourne · B.Tech Electronics and Communication Engineering (IoT and Sensors), VIT Vellore

📌 Featured Projects

Autonomous Mining Vehicle Localisation UKF sensor fusion (IMU + LiDAR AMCL + GPS) in ROS that keeps a vehicle localised when GPS drops out in tunnels. Error grew about 3× slower than LiDAR alone in simulation. Tested on a custom robot. ROS UKF Gazebo LiDAR SLAM Python

Lexus Special Projects: Automotive R&D Internship VIP lounge seat conversion and off road kit for a Lexus LX570, plus PID controlled extending walls for a truck mounted mobile showroom. Real vehicles, delivered to clients. Wiring harness ECU diagnostics Arduino PID control Fusion 360

Autonomous Plant Monitoring Robot Wheel odometry error model (6.1 cm/m drift), odometry and vision fusion, mission logic and LiDAR obstacle stopping. Cut detection turnaround from 30–60 s to under 5 s. ROS Sensor fusion Odometry LiDAR YOLO Python

Prusa MK4S Design for Manufacture Redesigned printer parts for CNC, injection moulding and sheet metal, then inspected the fabricated parts against tolerances. Y axis assembly took 18 min against 37 min predicted. SolidWorks DFM/DFA Tolerance analysis Manufacturing
