EXPERIENCE

Robotics Research Aide Jan’20-Present

• Worked on building small autonomous vehicles with a Proportional-Derivate (PD) Controller and a LiDAR sensor.

• Currently working on developing an accompanying middleware in ROS to operate the vehicle in a physical testbed. Used PyQt5 for creating the GUI for the robot.

• Used SolidWorks for modelling the Robot and its components and imported the Robot’s URDF in Gazebo for simulation. PROJECTS

Autonomous Surveillance Drone Jan’19 – Apr’19

• Used Robot Operating System (ROS) and Python for making the drone move autonomously and making it land in a specific spot by detecting Aruco markers using camera feed from the drone.

• Worked on You Only Look Once (YOLO) for object detection and sending only the required frames of interest to the master node.

• Worked on Path planning optimisation of a mobile robot moving from an initial given point to a final point B with respect to static obstacles using Rapidly-exploring Random Tree – Star (RRT*) algorithm.

• Implemented Sequential Quadratic Programming (SCP) technique for determining the optimised path. Trajectory planning KUKA Robot Sep’18-Dec’18

• Developed a mathematical model of 7-Degrees of Freedom (DOF) KUKA Robot using MATLAB.

• Evaluated the Denavit–Hartenberg (D-H) parameters, performed forward and inverse kinematics using Jacobian Inverse method and performed the trajectory planning using Cubic polynomial and found the required joint pose and velocities.

• Validated the solution by simulating the experiment in MATLAB using Peter Corke’s Robotics toolbox and checked for obstacle collision.

Optimisation of a brake disc dimensions Sep’19 – Nov’19

• Performed Structural Analysis using ANSYS on the brake disc with respect to frictional and centrifugal forces to find its maximum von Mises stress.

• Performed DOE using Latin Hypercube Sampling and used Kriging method for response surface evaluation.

• Optimized the geometry using Non-Linear Programming by Quadratic Lagrangian (NLPQL) resulting in reduction of Equivalent stress (Von Mises) by 3.5% and Geometric volume by 20%. Finite Element Analysis Projects Jan’19 – Apr’19

• Programmed a MATLAB code to analyse the performance of a 2-D steel fabricated cooling fin by determining its temperature and heat flux fields using linear, quadratic and cubic elements and computing the respective rate of convergence. o Validated the MATLAB solution by computing the same problem using ABAQUS and comparing both the solutions. o Used Richardson Extrapolation for conducting Mesh Refinement test by estimating the error for each analysed mesh.

• Performed FEA Analysis using ANSYS for a given Plexiglass design to find its ultimate tensile strength, factor of safety and drop height when subjected to a 10-pound mass.

OTHER WORK EXPERIENCE

Arizona State University (ASU), Tempe, AZ: Bike Specialist Oct’18 - Present

• Working as a part time Mechanic in ASU Bike Co-op for 18 hours/week which involves assembly, disassembly of bikes and bike parts such as gears, bottom brackets, brakes and axles.

• Used techniques like 5S, Kaizen for mistake proofing and improving the work efficiency. Air India Limited: Engineering Intern Jun’17

• Served as a Basic Maintenance Engineer in Basic Maintenance Division, Air India.

• Performed maintenance, repair and overhaul of aircraft parts in B-737, B-747, B-777, B-787.
