Walking an Unknown Street with Bounded Detour
A polygon with two distinguished vertices, s and g, is called a street iff the two boundary chains from s t o g are mutually weakly visible. For a mobile robot with on-board vision system we describe a strategy for finding a short path from s t o g in a street not known in advance, and prove that the length of the path created does not exceed 1 + 2. times the length of the shortest path from s ...
متن کاملGoing Home Through an Unknown Street
We present a new strategy for searching for a goal in a street. The strategy works in two phases. First it follows an angular bisector, then it uses circular arcs based only on one side of the street. A competitive factor of 1.514 is achieved which is remarkably close to the lower bound of √ 2. Secondly, we assume that the location of the goal is known to the robot. We prove a lower bound of √ ...
متن کاملAN INVERSE PROBLEM WITH UNKNOWN RADIATION TERM
In this paper, we consider an inverse problem of linear heat equation with nonlinear boundary condition. We identify the temperature and the unknown radiation tern from an overspecified condition on the boundary
متن کاملDIRECT ADAPTIVE FUZZY PI SLIDING MODE CONTROL OF SYSTEMS WITH UNKNOWN BUT BOUNDED DISTURBANCES
An asymptotically stable direct adaptive fuzzy PI sliding modecontroller is proposed for a class of nonlinear uncertain systems. In contrast toother existing approaches of handling disturbances, the proposed approachdoes not require this bound to be known, only requiring that it exists.Moreover, a PI control structure is used to attenuate chattering. The approachis applied to stabilize an open-...
متن کاملDynamic Bipedal Walking while Carrying an Unknown Time-Varying Load
In recent years, there has been tremendous interest in employing legged and humanoid robots for dangerous missions in disaster and rescue scenarios, requiring robots to operate swiftly and stably while dealing with high levels of uncertainty and large external disturbances. One such practical example is using a legged robot to carry and manipulate large and heavy objects whose mass is not known...
