DESCRIPTION:Prof. Metin Sitti (Robotics Institute\, Carnegie Mellon Univer
 sity\, Pittsburgh)\nABSTRACT :\nMiniature mobile robots have the unique ca
 pability of accessing to small spaces and scales directly.  Due to their 
 small size and small-scale physics and dynamics\, they could be agile and 
 portable\, and could be inexpensive and in large numbers if they are mass-
 produced.  Miniature robots would have potential future applications in h
 ealth-care\, mobile sensor networks\, desktop micro-manufacturing\, enviro
 nmental monitoring\, and inspection.  In this presentation\, miniature mo
 bile robots with tens or hundreds of micrometer overall sizes and various 
 locomotion capabilities are presented.  Going down to tens or hundreds of
  micron scale robots\, significant challenges are on-board actuation and p
 ower sources.  Two alternative approaches are proposed in this talk to so
 lve this challenge.  First\, external powering and actuation methods are 
 used to move permanent magnet micro-robotic bodies using a stick-slip dyna
 mics\, spinning or rolling based surface locomotion on planar surfaces in 
 air or in liquid in 2-D.  Vision-based control schemes can individually c
 ontrol single- or teams of micro-robots and these robots can manipulate an
 d assemble micro-parts with or without contact in liquid.   Controlled a
 ssembly and disassembly of such multiple magnetic micro-robots are also in
 vestigated and demonstrated towards reconfigurable micro-systems in 2-D. 
  As the next approach\, a hybrid (biotic/abiotic) actuation principle is u
 sed to propel micron scale robotic bodies in liquid by harvesting the flag
 ellar propulsion of attached bacteria.  Stochastic swimming of these S. m
 arcescens bacteria attached micro-objects can be stopped and resumed repea
 tedly using chemical switching.  Their motion can be steered using contro
 lled chemical gradients in the liquid medium.  Preliminary stochastic dyn
 amics and steering of such bacteria propelled micro-objects are demonstrat
 ed by simulations and experiments.\n\n\nABOUT THE SPEAKER :\nMetin Sitti r
