SUMMARY:Some Problems on Multi-Sensor Layout Optimization
LOCATION:Virtual
DESCRIPTION:Abstract: Robots or robotic applications, like living beings, perceive the 
 world through a great variety of sensors. For range sensors, be it acoustic
  like sonar, photic like cameras, laser beams, or lidars, the sensing range
  can, to some extent, be ideally abstracted as either 1D lines or 2D circle
 s. Hence, it would be helpful to study the properties of the underlying geo
 metric problems, and studying these problems can in turn help with getting 
 the optimal solution of these problems.\n \nThe thesis starts with two 1-D 
 sensing models (homogeneous and heterogeneous) for covering the boundary of
  a 2D region with gaps created by obstacles, then it gets into coverage wit
 h a 2D sensing model for both the interior and the boundary of a 2D region.
  These two problems can be seen as variants of barrier coverage problems th
 at separate the inside of certain regions from the outside. We then general
 ize the barrier coverage problem by formulating the problem of separating m
 ore than two sets of regions, which we termed as the barrier forming proble
 m. As the most common sensing robots are mobile, we continue to study mobil
 e sensing robots forming a wavefront to sweep a region, and this turns out 
 to be similar to the perimeter guarding problem with evolving perimeters an
 d connects to the first problem studied. Lastly, we introduce a relevant re
 al-world application for placing UV lights for sanitizing 3D surfaces like 
 hospital rooms, trains, or buses.\n \n
