In video games and robotics, one often discretizes a continuous 2D environment into regular grid with blocked unblocked cells then finds shortest paths for the agents on resulting graph. Shortest paths, of course, are not necessarily true in environment. this article, we therefore study how much longer path can be than corresponding all grids that tessellate environments. We 5 different vertex ...

aim: level of physical activity as key determinant of healthy lifestyle is less than what isrequired in individuals particularly women. applying theories of behavioral change aboutcomplex behaviors such as physical activity leads to identify effective factors and their relations.the aim of this study was to determine predictors of exercise behavior based on developedtheory of planned behavior w...

Path planning for an autonomous vehicle can occur at two different times. First, path planning might occur at mission specification time when the vehicle’s initial path is determined and used to specify other mission factors. This task makes use of some model of the environment in planning a path that will avoid obstacles and hazardous areas. A second type of path planning might occur while the...

Unmanned Aerial Vehicle (UAV) path planning is divided into off-line static path planning and real-time dynamic path planning. The former one is applied to the ideal situation that the terrain has been clear, and there is no unexpected situation in flight. Actually, however, the flight situation is very complex, we have to adopt real-time path planning based on off-line static path planning. To...

Motivated by fluid analogies, artificial harmonic potentials can eliminate local m in ima problems in robot path planning. I n this paper, simple analytical solut ions t o planar harmonic potentials are derived using tools f r o m fluid mechanics, and are applied t o two-dimensional planning among multiple moving obstacles. These closed-form solutions enable real-time computation to be readily ...

Path planning is the key task in the field of Robotics. The modelling environment and algorithm to find shortest, collision free path are the basic issues in the path planning problem of the robot motion planning. This paper presents a literature review of different path planning techniques in static as well as dynamic environment. Planning a path in static environment is easy as compared to dy...
