problem solver.

PROFILE / MECHANICAL ENGINEERING UNDERGRADUATE

I approach mechanical problems the way a drawing approaches a part — dimension first, structure second, decoration never.

Currently in my second year of Mechanical Engineering at NIT Delhi, minoring in AI/ML. My work sits between CAD geometry and the calculations that justify it — chassis layouts, drivetrain sizing, load estimation — with a growing interest in applying computational methods to renewable-energy systems.

TWO CASE STUDIES / DESIGN + COMPUTATION
Unmanned Ground Vehicle
MECHANICAL DESIGN / DRIVETRAIN / POWERTRAIN — TEAM OF 3

A 4-wheel differential-drive UGV modelled end-to-end in Fusion 360: a compact two-compartment chassis housing motors, power source and electronics, with a drivetrain and shaft sized against calculated traction and torque requirements for inclined-terrain operation.

MY CONTRIBUTION
CAD modelling + engineering calculations. Structural (ANSYS) analysis was performed by a teammate.
COMPARTMENT ACOMPARTMENT B400 MM

Two-compartment rectangular chassis, 400 × 250 × 160 mm, laid out for motor, battery and electronics mounting.

DIFFERENTIAL DRIVE

4-wheel differential-drive configuration with independent motor-to-wheel transmission on each side.

INCLINE θTRACTION F

Traction-force and required-power estimation for inclined-terrain operation, driving motor and torque selection.

SHAFT

Shaft diameter derived from calculated torque and loading for motor-to-wheel transmission.

APPROACH

How I approach
engineering.

SIX-STAGE PROCESS / CLICK TO EXPAND
01
Understand
Define the problem, constraints and operating conditions before touching CAD.
02
Model
Build the CAD geometry — chassis, assemblies, component layout.
03
Calculate
Derive loads, forces and power requirements from first principles.
04
Analyze
Check the numbers against the geometry and operating scenario.
05
Optimize
Refine dimensions, mass and component selection for the target performance.
06
Validate
Cross-check results and, where needed, hand off for structural analysis.

UPS LAKSHMI, ROHTAK / OBSERVATIONAL VISIT

Industrial visit to UPS Lakshmi, Rohtak, observing nut and bolt manufacturing processes and industrial production workflows first-hand.

This was an observational visit — I did not personally operate the manufacturing equipment.
