Walking Streets Faster
A fundamental problem in robotics is to compute a path for a robot from its current location to a given goal. In this paper we consider the problem of a robot equipped with an on-board vision system searching for a goal g in an unknown environment. We assume that the robot is originally located at a point s on the boundary of a street polygon. A street is a simple polygon with two distinguished...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Better Utilization of City Streets
City streets in this country represent an annual capital outlay of $3,133 billion, based on 1966 data. This figure is more than one-third of the total annual capital outlay for all streets and highways, $9,123 billion. Another $1,114 billion was spent annually for maintenance of city streets, so $4,247 billion was spent each year on city streets. O f this total $4 billion, $2.5 billion went to ...
متن کاملRandomized Strategy for Walking in Streets for a Simple Robot
We consider the problem of walking in an unknown street, for a robot that has a minimal sensing capability. The robot is equipped with a sensor that only detects the discontinuities in depth information (gaps) and can locate the target point as enters in its visibility region. First, we propose an online deterministic search strategy that generates an optimal search path for the simple robot to...
