DESCRIPTION:Prof. Metin Sitti\, Robotics Institute\, Carnegie Mellon Unive
 rsity\, Pittsburgh\nMiniature mobile robots have the unique capability of 
 accessing to small spaces and scales directly.  Due to their small size a
 nd small-scale physics and dynamics\, they could be agile and portable\, a
 nd could be inexpensive and in large numbers if they are mass-produced.  
 Miniature robots would have potential future applications in health-care\,
  mobile sensor networks\, desktop micro-manufacturing\, environmental moni
 toring\, and inspection.  In this presentation\, miniature mobile robots 
 with tens or hundreds of micrometer overall sizes and various locomotion c
 apabilities are presented.  Going down to tens or hundreds of micron scal
 e robots\, significant challenges are on-board actuation and power sources
 .  Two alternative approaches are proposed in this talk to solve this cha
 llenge.  First\, external powering and actuation methods are used to move
  permanent magnet micro-robotic bodies using a stick-slip dynamics\, spinn
 ing or rolling based surface locomotion on planar surfaces in air or in li
 quid in 2-D.  Vision-based control schemes can individually control singl
 e- or teams of micro-robots and these robots can manipulate and assemble m
 icro-parts with or without contact in liquid.   Controlled assembly and 
 disassembly of such multiple magnetic micro-robots are also investigated a
 nd demonstrated towards reconfigurable micro-systems in 2-D.  As the next
  approach\, a hybrid (biotic/abiotic) actuation principle is used to prope
 l micron scale robotic bodies in liquid by harvesting the flagellar propul
 sion of attached bacteria.  Stochastic swimming of these S. marcescens ba
 cteria attached micro-objects can be stopped and resumed repeatedly using 
 chemical switching.  Their motion can be steered using controlled chemica
 l gradients in the liquid medium.  Preliminary stochastic dynamics and st
 eering of such bacteria propelled micro-objects are demonstrated by simula
 tions and experiments.
