Electric Go-Kart | Team Phoenix Racing July 2018 - Feb 2019
-
As a part of our college's FSAE team, we developed an electric go-kart and participated in the 6th Electric Go-kart Design Challenge held at India's premier F1 track, "The Buddh International Circuit" in February 2019.
-
I was responsible for the design of vehicle dynamic systems (steering system, wheel hubs, and the weight distribution) of the kart, 3D modeling of various vehicle components using Solidworks, thermal analysis of battery pack, and the structural analysis of wheel hubs. I was also responsible for maintaining the treasury of the team and hence make a cost-report for the kart.
-
The autocross and skidpad events being the tests for suspension and steering systems, I was extremely satisfied when we obtained first position in both the events.
-
This was the first time our team entered an electric vehicle design competition and we won 7 different awards at the competition including the title of Champions of E-GKDC 2019 in our first attempt at the competition.
Battery Thermal Management System May 2019 - August 2019
-
I got an opportunity to work as a Globalink Research intern and work at the Heat and Mass transfer lab under the supervision of Prof. Shohel Mahmud at University of Guelph, ON, Canada in the summer of 2019.
-
I performed the battery discharge test at different discharge rates to obtain the temperature plot at the surface of a single Li-Ion cell.
-
This study can be used to calibrate simulated batteries working as a substitute for the real cell, as working with Li-ion batteries can be dangerous.
-
I created a passive system using porous media to study the heat dissipation through the embedded simulated battery cells. I tested 5different samples of porous media with varying pore densities and porosities studied the effects of these porous media parameters on heat dissipation by observing the Ra-Nu variation for heating and cooling cycles at 5 different discharge rates.
Air Shock-Absorber | Capstone project August 2019 - May 2020
-
As my undergraduate capstone project, I worked on development of an air shock-absorber for two wheeled vehicles under the guidance of Prof. Hemant Nagarsheth.
-
This project aims to use atmospheric air instead of compressed air for damping the oscillation of a suspension system.
-
I developed the 3D model of the system and the quarter-car model of the proposed system and tested it on the Simulink environment.
-
Due to Covid-19 outbreak, the experimentation of the system could not be completed and hence only the simulation study was submitted as the capstone project.
Lane detection
As a start to image processing and perception for self-driving cars, I implemented a lane-detection algorithm using OpenCV library in python3. Click on the project name for a link to the Github repository.
MPC control
I developed python codes for the lane change maneuver using PID control and the Model Predictive Control. I used the kinematic bicycle model for the dynamics and the Linear Time-Invariant system for the PID and MPC control. I observed the difference in tuning of control parameters and oscillatory response between PID and MPC techniques.
SLAM using Kalman Filter
As a part of a Coursera project, I implemented an error-state Kalman Filter for state-estimation and localization of a self-driving cars using LIDAR, IMU and GPS measurements. I also implemented basic least square estimator, linear Kalman filter and an extended Kalman filter using python.
Line-Following Robot
Made a Line-following robot using IR sensor arrays and Atmega32 microcontroller for detection of white line on a black background. Incorporated a weighted sensor algorithm for tracking the white line.
Won a line-following robot contest in our freshmen year at our college level.
All-terrain robot
In my freshmen year, I made a simple wired robot with a gripper mechanism to complete various manual tasks including moving balls from one place to other via a rough terrain. The bot reached the final stage of an all-terrain vehicle contest.
