Autonomous Maze Navigating Robots, Intro to Robotics January 2019 – May 2019

Coded robots using LabVIEW and Arduino to autonomously navigate mazes involving walls and edges

Programmed robots using A* (A-Star) path planning and ultrasonic and IR sensors to detect obstacles Wireless Power Transfer, Rail Propulsion Systems & NCDOT August 2018 – May 2019

Designed and built a scale model wireless power transfer (WPT) system using two coils

Automated Simulink circuit simulations using Matlab, saving 150 hours of human labor

Built and coded an interactive 32x32 LED display using an Arduino that responded to user input moving the coils Crane Robot, Junior Design, UNC Charlotte January 2018 – May 2018 Project Lead

Created schematics for the controls system of a crane robot to navigate an obstacle course and transport blocks

Coded an Arduino to accept controller input and control drivetrain and crane servos

Performed load distribution and incline stability calculations in Mathcad to aid design

Designed and 3D modelled the crane subsystem in Creo and fabricated crane assembly using a Mill and a 3D printer

Unique dual motor crane setup resulted in shorter block loading times and a smaller frame to navigate course faster

Robot had fastest time out of 12 teams

Miniature Air Engine CAD and Fabrication January 2017 - May 2017

Modeled a functional (2” x 2” x 4”) Air Engine in Creo and produced part drawings for fabrication

Fashioned a cutting tool to be used on the lathe using a Grinder

Machined the parts made of Aluminum and steel using a Lathe, Mill, Bandsaw and Sander within +/- 0.010” WORK EXPERIENCE:

UNCC Motorsports Research, UNC Charlotte Research Intern June 2018 – July 2018

Conducted study on driving point impedance of a human hand controlling a steering wheel

Designed with Solidworks and fabricated a test bed comprising of a motor, steering wheel and a load cell

Assembled circuitry to control the motor and log experimental data such as encoder position and grip force

Ran tests using Simulink which sent torque pulses to motor and recorded sensor data

Wrote MATLAB code to analyze sensor data using linear regression to get impedance of a human hand w.r.t grip force Mechanical Engineering Department, UNC Charlotte Teaching Assistant August 2017 – May 2019

Graded weekly home-works and quizzes for a class of 50 students for Statics and Solid Mechanics courses

Coached and answered student questions in office hours and Supplemental Instruction sessions
