About
Welcome to my personal portfolio! This website is custom made using HTML, CSS, and Bootstrap.
Welcome to my web resume! My name is Nikhil and I'm an Engineering Science (Aerospace) student at UofT with a particular passion for the intersection of robotics and aerospace. I am in my final year of undergraduate studies, and have past experience working in formal robotics lab settings, as well as experience working in the Canadian space industry. I have contributed to real and anaologue space missions, primarily to the BEACON mission which will explore the lunar south pole with a small CubeRover. My research interests are in enabling long-duration autonomy in unstructured environments. Robotics and aerospace have been long-term passions of mine, stemming from a childhood love of space exploration, and I'd love to continue getting experience working in those domains.
This site is intended to serve as a supplement to my resume. It contains information that I didn't have enough space to fit in my resume, but that I still feel is worth talking about somwehere. Feel free to add me on LinkedIn, and take a look at my GitHub for examples of the public code I've written in the past!

- During Covid, derived a custom wheel based odometry algorithm to track the robot's position on the field while autonomous
- Continue to mentor this team - in 2021, led the team to the VEX World Finals in Dallas, Texas for the first time in the team's history
Personal Projects
Stirling Engine
Jan 2021
- During COVID, attempted to design a functional Stirling Engine as a physics project
- Determined physical constraints, and developed a mathematical model to aid in choosing physical parameters
- Used Solidworks to CAD the engine, then ordered parts and constructed it
- Unfortunately, the engine ran into frictional issues that could not be easily overcome without additional spending on parts
- All of this was done for a physics class, and I documented every step, available here
Holonomic Pure Pursuit Simulator
Jan 2021
- Motivation
- It had been a longtime personal goal of mine to implement Pure Pursuit type path following algorithms for autonomous control of VRC robots (see VRC)
- During Covid lockdowns, I was unable to test these algorithms on a physical VEX robot
- Instead, I decided to simulate them virtually so that I could implement them on a physical robot later (unfortunately I graduated before lockdowns were lifted)
- Developed a Python based simulator using a Tkinter frontend to simulate the first order dynamics of a holonomic drivetrain (using high school physics concepts)
- Implemented a path planner and Pure Pursuit controller on this virtual drivetrain, assuming perfect odometry input
- Given an initial and target robot pose, the algorithm first interpolates between them using a Hermite spline (a cubic), then samples a number of discrete waypoints along the spline
- At each step, the drivetrain follows a simple proportional control loop targeting one of these waypoints - once it gets close enough, it switches the target to the next waypoint along the spline
- This process repeats, while angular error is handled by a separate proportional control loop (can be decoupled since the system is holonomic)
VEX COTS Spacing Calculator
May 2020
- Motivation
- When assembling mechanisms for VRC (see VRC), improper spacing in the assembly of VEX COTS parts can lead to flimsiness or a drop in performance (usually due to friction)
- This is normally aleviated by using CAD software (ie. Solidworks) to plan out the relative spacing of each part, but that is unwieldy when rapidly prototyping to test design ideas
- This leads to prototypes being flimsy/inefficient, which provides a skewed understanding of design ideas
- Developed a Tkinter based application in Python to aid in rapidly calculating the optimal spacing between VEX COTS parts
- This part spacing tool allows users to virtually test out combinations of COTS spacing elements between standard VEX parts - this is much faster than full blown CAD, and requires no physical guesswork
HSS Course Filter
July 2022
- Motivation
- EngSci students are required to take a certain number of Humanities & Social Science (HSS) courses throughout our degree - most students take one in their 4th semester
- These courses are usually offered by a different faculty, so scheduling with EngSci 2nd year timetables was a challenge at the time - there were 700+ valid HSS courses, but most were not running in 4th semester or were incompatible with our schedules
- There was no existing tool provided by the university to filter HSS courses by compatibility with personal timetables - so I made my own
- Created a web-scraping tool using Selenium (in Python) to iterate through a list of valid HSS courses and query UofT's course info website for scheduling info on each one
- Results were compiled into a JSON containing only courses that were running in 4th semester
- Wrote another Python program to take in an individual's timetable as a CSV, and filter it against the JSON to provide a list of courses with no scheduling conflicts
- For my schedule, this process narrowed down my list of possible courses from 742 to 29
- Distributed the JSON and filtering program to my peers
- Unfortunately, within a few days UofT made their course info website inaccessible to Selenium bots, possibly as a result of my script's abuse - as a result this script is no longer functional
Schoolwork Management Spreadsheet
Dec 2021
- Created a Google Sheets + Query Language spreadsheet to manage my schoolwork throughout the term - for the past couple of years, I have used this in place of a personal calendar and to-do list
- At the start of each term, I manually populate the spreadsheet with assignment due dates and mark breakdowns
- The sheet uses the Google Visualization API Query Language to generate a continuously updating to-do list of items due in the coming days
- This to-do list is organized so that the earliest due tasks appear first, with their colour indicating their importance (mark-distribution wise)
- As tasks are completed, they can be marked off of the sheet, which removes them from the to-do list
- When marks are released for assignments, they can be added to the sheet to compute per-course marks to-date and projected marks
- Distributed this sheet to my peers, some of whom still use it on a daily basis
- A copy of this sheet is available here
IoT Lights
June 2023
- For a birthday gift, created sets of RGB lights that pull from the Internet to remain synced to the same colour
- Used Raspberry Pi Picos to periodically pull data from a private Discord server as a POST request, then set pinouts to make lights the correct colour
- User control is via Discord - any messages sent in the private Discord server are taken as commands by the Picos
- Each Pico and light pair was soldered together to form a single, standalone IoT device
Bridge Calculator
Nov 2021
- Developed a Python program to (approximately) calculate the loads present on a hybrid truss/beam bridge
- This was for a bridge design project in my first year Civil Engineering course, but this program went above and beyond by being able to calculate the loads on any arbitrary system of truss members
- My team used this program to design an optimal bridge, then constructed it out of matboard and tested to failure
