Manual drilling machines require constant operator involvement and lack precision for repeated tasks. We designed an NC Drilling Machine on a 3-axis system — similar to a 3D printer — to automate drilling of soft materials like wood.

Responsible for designing the machine axes and overall orientation. Designed the motion system using stepper motors and lead screws, and created 3D printed motor mounts. Collaborated with the electrical team for Arduino-based motor control.

Vibration during drilling caused inaccurate positioning. Solved by adding chromium smooth rods alongside each lead screw to stabilise the moving block.

• Designed 3-axis lead screw + smooth rod system in SolidWorks
• 3D printed custom motor mounts and carriage blocks
• Integrated NEMA stepper motors with Arduino
• FEA stress & displacement analysis on critical parts
• Motion study simulation to validate movements

Final project for the ACMEGRADE AutoCAD internship — recreating the iconic Lamborghini Countach as a detailed 2D technical drawing with side, top, and rear orthographic views with full colour and layering.

The reference drawing was provided. My task was to replicate it accurately in AutoCAD — all dimensions had to be interpreted and adjusted by me from proportional analysis and automotive knowledge.

• Studied reference views and planned layer structure
• Built geometry using polylines, arcs and splines
• Self-determined all dimensions from proportional analysis
• Applied colour hatching for body, glass and chassis
• Annotated with dimensions and technical notes

Earned both Trainee Completion and Internship Completion certificates from ACMEGRADE.

A lightweight soft robotic glove for hand rehabilitation and assisted grip. Uses soft pneumatic actuators that mimic natural finger bending — safer, lighter and more comfortable than rigid exoskeletons.

Responsible for design and FEA analysis of soft pneumatic actuators — modelled as multi-body parts to simulate bending motion and determine internal pressure requirements. Also designing all 3D printed connecting parts, finger joints and housing box.

Designing soft actuators that produce sufficient bending force while remaining flexible, lightweight and manufacturable via FDM.

• Designed actuator geometry as multi-body SolidWorks part
• FEA to simulate bending motion under pneumatic pressure
• Determined required internal pressure for full finger flexion
• Designing 3D printable finger joints and housing components

In active development — Initial linear actuator prototypes fabricated and tested.
