Professional Experience

Research Assistant at Next Generation Systems Group (NGS) at UT Arlington, Texas – Worked on development, testing and characterization of mems pressure sensors robot skins. Nov 2014 – Dec 2015

Research intern at TATA Power Strategic Engineering Division, India – Designed Airfield lamp monitoring and control system using AT89C2051 controller, AMIS 49587 power line modem May 2012 – April 2013

Master’s Thesis

Development, Testing and Characterization of Electronic Skins for Robot (Supported by National Sci. Foundation (NSF))

Software – LabVIEW, Matlab. Hardware – NI cRIO, FPGA Modules for cRIO, Load cell and Linear Actuator. As a part of development, performed Electrohydrodynamic (EHD) printing on MEMS pressure sensors using PEDOT: PSS piezoresistive as a base material. Newly developed piezoresistive pressure sensors, integrated in soft robot skin materials, were tested and characterized. Automated the testing and data acquisition process. Different testing parameters used such as MEMS sensors, robot skin materials and geometry along with application of sinusoidal movement and constant force methods. Manufactured an interface hardware using Wheatstone bridge and Opamp. Implemented, explicit Force control and impedance control schemes.
