Radiological
Contamination Search and Mapping using Unmanned Autonomous Systems with
Plug-and-Play Interchangeable Components: Co-PI, DOE,
Savanna River Nuclear Solutions, LLC (Sept 27, 2017 to Sept 26, 2018, $
321,055) The study addresses a
potential use of UAS based mobile sensor network for radiation contour
mapping and source searching in low-altitude clustered environments. |
Tailoring
mechanical implant for curing obstructive sleep apnea(OSA) using CT scan
based computational model: PI, Faculty Opportunity
Award (UNLV) (July 1, 2018-June 30, 2019, $
20,000) In the search of an
affordable solution to alleviate sleep apnea, a simple mechanical implant
device was designed. To validate the effectiveness of the implant device an
artificial lung based experimental testbed is used. In this testbed different
parts of muscles located around a human air path is made of silicon with
appropriate modulus and displacement and pressure sensors are embedded for
measuring displacement and pressure changes at the air path during OSA
patient breathing cycle. |
Radiological
Contamination Search and Mapping Using Unmanned Autonomous Systems with Plug
and Play Interchangeable Components: Co-PI, Savannah
River Nuclear Solution LLC (Sept 26, 2016-Sept 25, 2017, $303,227) |
Development
of Plug-and Play Interchangeable Components for Unmanned Aerial System with
Mobile Manipulation Capability: Co-PI, Savannah River Nuclear Solution
LLC (June 2015-May 2016, $ 249,282) The objective of the
project is to develop plug-and-play interchangeable components for an aerial
robotic unmanned autonomous system (UAS). These components include (1) an
advanced radiation sensor for simultaneous neutron measurements and gamma-ray
spectroscopy, (2) a chemical sensor for measurements of vapors in air, and (3)
a miniature robotic hand manipulator to handle in-situ sampling and related
tasks. In addition, the UAS-based method of remote sensing of radiation and
source localization will be developed. |
Enhanced
Situational Awareness using Unmanned Autonomous Systems for Disaster
Remediation: Co-PI, NSF(August 2014-July 2017, $140,000) The goal of this project is
to enhance the situational awareness capabilities of law enforcement agencies
and first responders by employing unmanned autonomous systems (UAS) with high-resolution
sensing and imaging capabilities for disaster remediation. This is a
collaborative research between University of Nevada, Reno and University of
Utah. |
Advanced
Electroactive Polymer Actuators and Sensors for Aerospace Robotic
Applications: Co-PI, NASA EPSCoR (Sept
2013-Aug 2016, $ 1,125,000) The ultimate goal of this
project is to advance the development and understanding of electroactive
polymer actuators and sensors for emerging aerospace robotic systems. Specifically,
the work focuses on material processing, modeling and control, and
systems-level integration for electroactive polymers. Novel electroactive
polymers such as ionic polymer-metal composites give large deformation when
voltage is applied; and conversely, produce a measurable voltage when strained
for sensing applications. Electroactive polymers can be exploited to create
artificial muscles, actuators for robotics and compliant positioning systems,
and embeddable miniature sensors for detecting strain, pressure, and force. |
Agile
and Robust Monitoring of NPP: Sandia National Laboratory, PI, (Feb 2013-Jan 2015, $209,978) The project is to outline
proposed activities for the development of physical security planning and
physical protection system (PPS) design as well as consequence analysis for
an advanced nuclear power plant (NPP). |
Development of Ultrafiltration Membrane-Separation Technology
for Energy-Efficient Water Treatment and Desalination Process: Department
of Energy (DOE/BER) PI, (June 2012-Sept 2016, $512,000) Although
pressure driven membrane-based water purification process, such as
ultrafiltration (UF), nanofiltration (NF) and
reverse osmosis (RO), can offer energy-efficient and environmentally friendly
solution to clean water production, its broader use in large-scale fresh
water production has not materialized. The membrane-based water purification
technology can be potentially used in removal of hazardous chemicals (i.e.,
arsenic, pesticides, organics) from water. |
Robotic Catheterization Using Ionic Polymer-Metal Composite Actuator: PI, NSF CISE (Computer Information Science & Engineering) Computer Research Infrastructure (CRI) grant (June 1, 2010-May 30, 2015, $321,898) Robotics has undergone dramatic changes during the past years. The leading edges of the changes include numerous innovations in medical robotics applied for surgery, diagnostics, drug delivery, and rehabilitation. Catheterization is becoming one of the most important medical practices since it engages minimally invasive medical procedures to administrate diversified medical functions. |
RI: Collaborative Research: Intelligent Microwave Power Transmission and Control System for Artificial Muscle-Driven Biomimetic Robotic Systems: PI, (National Science Foundation, IIS-RI, September 1, 2007-August 31, 2010) In this research, we introduce an innovative approach to use a wireless link between I-EAP based target locomotion units and a remote control/power unit. The remote unit can provide necessary intelligence to the target locomotion units for proper adaptation to changing environments and continuously supply power needed to drive them. The proposed approach, using a microwave-based power supply method, is useful-especially for a small scale undulatory locomotion system due to its untethered operation in complex, unstructured environments. |
Collaborative Research: Biologically Inspired Cilia-Driven Microscale Robots: PI, (National Sicence Foundation, CISE, Aug 1., 2003 - July 2007) The goal of this collaborative research effort is to develop biologically inspired cilia-driven smallscale-robots that are based upon a new, enabling technology, electroactive polymers (EAP). Of particular interest is the use of an electroactive polymer to produce an aquatic propulsor capable of suitable thrust and maneuverability.

Control Algorithms for Smart Fin PI, (ARL/UNLV Cooperative Research, SOldier FERST, May 1., 2003 - June 2008) The project goal is to enhance accuracy of extended range smart munitions and guided projectiles by providing real-time servo control capability of smart fin on projectile airframe. The smart fin is actuated by MFC (Macro Fiber Composite) actuator and the fin angle tracking performance in different angle of attack and wind speed is being validated in the wind tunnel.

Shock
Isolation Using Semi-Active Control Techniques The goal of the project is to develop a novel elastomer whose modulus can be actively controlled using electromagnet. Unique feature of the elastomer is that an external electromagnet can lower the storage modulus of the elastomer unlike other magnetorheological elastomer (MRE) that increases the modulus under external magnetic flux. The proposed bi-directional MRE can be useful for numerous military applications in shock isolation.
