Calculation of optimal paths in the configuration space using artificial potential fields and a* and d* algorithms for an articulated robot. Comparison of techniques

TLDR
A calculation path technique based on the configuration space in the case of an articulated robot of two degrees of freedom is used, choosing in each case the best option for each one of the techniques for the combination.
Abstract
In this paper, we use a calculation path technique based on the configuration space in the case of an articulated robot of two degrees of freedom. We propose the use of artificial potential fields to represent the configuration space and the use of techniques of artificial intelligence like A* and D* to search a free collision path into the configuration space. This combination of techniques can be used in static and dynamic environments with more than three dimensions without considering the geometry of the obstacles. The results for this combination of techniques are presented, choosing in each case the best option for each one of the techniques for the combination.

Robot motion planning: a distributed representation approach

TL;DR: A new approach to robot path planning that consists of building and searching a graph connecting the local minima of a potential function defined over the robot's configuration space is proposed and a planner based on this approach has been implemented.

The focussed D* algorithm for real-time replanning

TL;DR: An extension to D* that focusses the repairs to significantly reduce the total time required for the initial path calculation and subsequent replanning operations for dynamic environments where arc costs can change during the traverse of the solution path.

Collision detection and avoidance in computer controlled manipulators

TL;DR: It is shown how the principles of hierarchical decomposition can be used to reduce the complexity of the manipulator trajectory planning problem and how it is possible to decompose the planning task so as to get the best of both cartesian space and joint space representations, and yet avoid the constant conversion overhead problem.

Computation of configuration-space obstacles using the fast Fourier transform

TL;DR: This paper presents a new method for computing the configuration-space map of obstacles that is used in motion-planning algorithms, and is particularly promising for workspaces with many and/or complicated obstacles, or when the shape of the robot is not simple.
