Path planning is one of important topics in robotics. When the mobile robot is building the map, it is better to use the higher resolution map in order to build a precise map. However, after the map building, if the resolution of the built map is very high, it takes much computational memory and time to perform the path planning.

The problem of automatic co!!ision-frce path planning is central to mobile robot applications. An approach to automatic path planning based on a quadtree representation is presented. Hierarchical path-searching methods are introduced, which make use of this multiresolution representation, to speed up the path planning process considerably.
EVOLUTIONARY PATH PLANNING FOR AUTONOMOUS AIR Multiresolution methods have been used in signal and adapted to the complexity of the signal content, as well as in our own past work [5,11,12] for path planning of autonomous robots with less stringent motion constraints.

Path-planning is an important primitive for autonomous mobile robots that lets robots find the shortest – or otherwise optimal – path between two points. Otherwise optimal paths could be paths that minimize the amount of turning, the amount of braking or whatever a specific application requires.

An Introduction to Mobile Robotics Mobile robotics cover robots that roll, walk, fly or swim. Mobile robots need to answer three fundamental questions Where am I Where am I going How do I get there To answer these questions the robot must first Make measurements Model the environment Localize it self Plan a path to its goal
multiresolution path planning method proposed in this paper. The idea is to use high resolution to represent the con?guration space in close proximity to the robot and to lower the resolution with increasing distance from the robot. This concentrates the planning resources to the begin of the path, the part that must
Abstract: The mobile robot can independently run the core as SLAM and path planning [1]. In the grid method drawing, high-precision positioning requires a high-resolution grid. When a mobile robot covers a certain working area, since the coverage width is constant each time, when high-efficiency coverage is required, a low-resolution grid is required for path planning, and a multi-resolution
planning. Path-planning can be considered as the process of navigating a mobile robot around a configured space, which has a number of obstacles in it that have to be avoided. 1. Nature of Navigation and Path-planning problem: In this section we define various terms that are used in mobile robot navigation and path-planning. new multiresolution hierarchical path planning algorithm for mobile agents with limited on-board computational resources. The proposed approach assumes that the agent (e.g., UAV) has detailed knowledge of the environment and the obstacles only in its vicinity. Far away obstacles are only partially known. The

Abstract: Safe and e cient path planning for mobile robots in large dynamic environments is still a challenging research topic. In order to plan collision-free trajectories, the time component of the path must be explicitly considered during the search. Furthermore, a precise planning near obstacles and in the vicinity of the robot is important.
A Path Planning and Obstacle Avoidance Algorithm for an Autonomous Robotic Vehicle. (Under the direction of Dr. James M. Conrad) Path planning in robotics is concerned with developing the logic for navigation of a robot. Path planning still has a long way to go considering its deep impact on any robot’s functionality.
