Electrical Engineer

Professional Summary

I was excited to learn about this opportunity.

Currently, I am working as a Research Associate at Robot lab, Florida

Institute for Human and Machine Cognition and responsible for improving the

Electrical system on a biped walking robot. Before that, I worked as

Research Engineer for a novel engineering project for biomedical

application at Sensory Processes Lab, Psychology dept, University of

Florida. And Before that, I graduated with dual MS Degree in

Electrical/Computer Engineering and Mechanical Engineering at University of

Florida. Before starting graduate school at University of Florida, I worked

for 2.5 years partly as a software engineer and partly as project leader

for a novel robotics R&D project at Automotive Center of Excellence, Satyam

Computer Services Ltd. Before that I got a B.Tech degree (Gold Medal) in

Electrical Engineering from one of the best 10 engineering institutions in

India.

During my graduate school at UF, I worked on various design projects. I was

the electrical team leader of SubjuGator 2010, the autonomous submarine

that represents UF at the AUVSI underwater competition. I am also the

Electrical Team Leader of the Human Powered Submarine (HPS) that represents

UF at International Submarine Race. I was also one of the major

contributors to the IEEE 2009 hardware competition team and HPS 2009 and

SubjuGator 2009. Apart from this, I have been a Teaching Assistant for

various design intensive labs - Senior/Junior Design, Power Lab, Digital

Logic Lab and Power Lab. My MS thesis work involved the Design and

implementation of a 6 axis Force/Torque sensor to be used for closed loop

control of an Industrial Robot Manipulator. I have accumulated quite some

hands on experience in designing and integrating electrical hardware and

robotics systems from scratch which involved low level embedded programming

in C/C++, digital design in VHDL, PCB design and hardware implementation

using Analog, Digital and Power Electronics, Signal/Sensor Data Processing,

Attitude Estimation, Linear Controls, Robot Geometry and

Kinematics/Dynamics.

I believe that my flexibility and persistence to succeed in any task that I

take up should make me better than most other applicants. Please refer to

my Resume (Attached) for details of my educational background, work

experience, research experience, achievements, publications and

teaming/managerial skills.

I will be glad to provide contact details of my recommenders if needed.

Pratt and Dr. Peter Neuhaus

I am working on the improving the Electrical Design for the biped walking

robot M2V2. Walking Algorithms tested on M2V2 will be applied on

Robonaunt2 (NASA's humanoid robot). I am working on applying EtherCAT bus

to communicate between computer and various motor driver modules while

ensuring maximum speed, least possible wires and robustness of protocol.

This involves making small motor driver modules (that can be embedded in

the limbs of humanoid robot) which can drive a brushless DC motor,

interface two Encoders for Position / Force, estimate velocity, closed

loop current and force control and have flexible interface using EtherCAT,

USB, SSI, LVDS and CAN. EtherCAT is a high speed (100Mbps) bus protocol

for automation applications which require short data update times.
