Hi, my name is Joyal Puthur
Engineering Precision Systems for Tomorrow’s Machines

Developed an open-loop interactive 3 degree of freedom platform featuring a maze on top, the orientation of the maze is controlled with a remote equipped with an IMU that provides acceleration data to a microprocessor that spits out motor angles to imitate the remote's orientation. The goal is to make the ball traverse through the maze. The entire project, from concept, backup plans, designing, prototyping, assembling, electronics, and writing code, was done in 24 hours.

Designed and developed an autonomous quadruped robot from scratch, integrating a 360-degree LiDAR module for real-time obstacle detection and navigation. Created the chassis design in SolidWorks and programmed control algorithms with central pattern generators, improving the robot's speed over 15%. This project combined mechanical design, sensor integration, and autonomous control systems to enhance navigation in dynamic environments.

Collaboratively developed custom G-code to enhance extrusion control in 3D food printing, achieving a print tolerance of 0.4mm and reducing failures. Our team modeled a PID control system in Simulink to maintain stable extrusion temperatures for consistent flow. Through testing and optimization, we improved material settings, achieving 2 mm layer accuracy and reducing material waste by 80g per print. Additionally, we implemented dual-point extrusion, enhancing overall printing efficiency and expanding the usability for various food textures.

This centrifuge was developed specifically for Kalika Enterprises to streamline the post-frying oil-removal process. It features a mesh drum that securely holds fried items while spinning inside an outer drum, effectively removing excess oil. Powered by a motor and pulley system, the centrifuge enhances product quality by reducing oil content and minimizes waste. The durable support frame ensures consistent, long-term use, making it an ideal solution for small food businesses aiming to boost efficiency.

Developed a triple tube heat exchanger system integrated with nano-enhanced phase change materials (NEPCM) for efficient thermal energy storage, achieving an 88.5% efficiency rate. Conducted comparative testing across three heat exchanger configurations: plain, with fins, and with fins plus nano elements. Results showed that the nano-enhanced system outperformed the standard PCM system, with approximately 3% faster charging and 5% improved discharging performance.
