Robotics Meets Neurology, UC Davis Style, with Dr. Sanjay S. Joshi

November 23rd, 2011 by

To introduce the Robotics component for the Virtual Reality, Simulation and Robotics course, the Health Informatics class welcomed Dr. Sanjay S. Joshi, a UC Davis, Associate Professor, in the Department of Mechanical and Aerospace Engineering.  Dr. Joshi heads the Robotics, Autonomous Systems, and Controls Laboratory, an interdisciplinary laboratory consisting of researchers from Mechanical and Aerospace Engineering, Electrical Engineering, Computer Science, and Biomedical Engineering.

"The Rat Pup Robots: the Robots that Act Like Rat 7-10 day old Rat Pups"

The Rat Pup Robots: the Robots that Act like Rats. Dr. Sanjay Joshi’s earlier research covered by UC Davis News and Information.

After an introduction to the tiny robots, namely, the Rat Pup Robots, We were introduced to his team’s current research into Brain-Muscle-Computer Interface (BMCI) for severely paralyzed persons.  The team’s research includes a mobile phone Prototype where EMG activity on the surface of a single face muscle site is recorded with a standard electrode.  The researchers then import the analog electrical signal  into an Android based mobile phone and it is digitized via an internal A/D converter.

Dr. Joshi’s research interests include:  Autonomous Systems/Control, Neuro-engineering and  Biorobotics.

He has recently returned from a sabatical appointment at Columbia University, where he held the post of Visiting Associate Professor with the College of Physicians and Surgeons, Department of Neurology.  In the recent publications of Dr. Joshi and his research team, we see the intersection of Neurology, Mechanical and Aerospace, and Electronic Engineering, Computer Science, BioMedical Engineering and great promise for future BMCI research here at UC Davis.<
