We're working on the Next Generation Robots and Systems that are increasingly small, cheap, integrated, and networked

Areas of Expertise
- Robotics, Manufacturing and Control Systems

Current Areas of Research
- Assistive Robotics and Micro/Nano Robotics
- My Research Laboratories, with up-to-date project information:

- NGS Lab, Department of Electrical and Computer Engineering, Univ. of Louisville, KY

- UTA Research Institute (UTARI)

I was an Associate Professor of Electrical Engineering at the the University of Texas at Arlington. My research group is called NGS (Next Gen Systems). Since January 2016, i am a Professor and Endowed Chair of Advanced Manufacturing at the University of Louisville in Kentucky.

I work on research related to multiscale robots and systems. Robotics is currently undergoing a major evolution away from expensive, bulky, and difficult to use machines, toward inexpensive, small, user-friendly and safe systems. As we witness this remarkable process, many unanswered questions pertaining to how we design, manufacture, and interact with the next generation of robots remain to be addressed. In the coming years, we will be able to answer these questions only if we know how to make and use increasingly complex microrobotic sensors and actuators. My current research in multiscale robotics aims to answer these questions, by looking at the following aspects:

  1. The size and precision of sensors, actuators and robots cuts across multiple scales from macro to nano. How do we design our microsystems and the robots that manufacture them in an intelligent way so that we can produce them in large numbers?
  2. The number or sensors, actuator and robots that must be aggregated varies between a few and large numbers. How do we network, coordinate, plan, and distribute the action of such collectives?
  3. The complexity and cost of microsystems and robots varies from low-complexity and low-cost, to highly integrated and reliable systems. How do we package and integrate sensors, actuators, into small devices and robots in a multifunctional, reliable and cost-effective manner?

About me:

I have a mixed CS/ME and EE background. I received my B.A. and M.S. degrees in 1993 and 1994, respectively, from Dartmouth College. During my M.S. I worked with Sunil Singh on force feedback haptics for spinal tap surgery. I received my Ph.D. in Electrical Computer and Systems Engineering from Rensselaer Polytechnic Institute in 1998. I worked with John Wen in nonholonomic motion planning for mobile and underactuated robots. Between 1998 and 2004, I was a Research Scientist at the Center for Automation Technologies (CAT) at RPI. During this time I worked on 20+ systems related projects in collaboration with industry. My principal collaborator during this period was the late Harry Stephanou (former ARRI director). I joined the University of Texas at Arlington in September 2004, with the Automation & Robotics Research Institute (ARRI) and the Department of Electrical Engineering. Between 2004 and 2010 i was a founding member of the Texas Microfactory initiative. Since January 2011, my research was being conducted at a the NGS laboratory located in Nedderman Hall (NH 250) and at the newly established assistive robotics labs at UTA Research Institute (UTARI, former ARRI). In 2016, my lab at UTA was slowly moved to University of Louisville in Kentucky, while my students graduated.
