OBPRM: an obstacle-based PRM for 3D workspaces

TLDR
This paper presents a new class of randomized path planning methods, known as Probabilistic Roadmap Methods (prms), which use randomization to construct a graph of representative paths in C-space whose vertices correspond to collision-free con gurations of the robot.
Abstract
Recently, a new class of randomized path planning methods, known as Probabilistic Roadmap Methods (prms) have shown great potential for solving complicated high-dimensional problems. prms use randomization (usually during preprocessing) to construct a graph of representative paths in C-space (a roadmap) whose vertices correspond to collision-free con gurations of the robot and in which two vertices are connected by an edge if a path between the two corresponding con gurations can be found by a local planning method.

Sparse Roadmap Spanners

TL;DR: This work proposes an approach, called spars, that provides the following asymptotic properties: completeness, near- optimality and the probability of adding nodes to the spanner converges to zero as iterations increase, which suggests that finite-size data structures may exist that have near-optimality properties.

Roadmap composition for multi-arm systems path planning

TL;DR: Results presented for a three-arm system and a model of the complex DLR's Justin robot show a significant performance gain of such a two-stage roadmap construction method with respect to single-stage methods applied to the whole system.

Probabilistic motion planning for parallel mechanisms

TL;DR: This paper proposes a general approach based on probabilistic motion planning techniques that combines random sampling techniques with simple but general geometric algorithms that guide the sampling toward feasible configurations satisfying the closure constraints of the parallel mechanism.

Ligand binding with OBPRM and user input

TL;DR: It is found that user input helps the planner, and haptic device helps the user to understand the protein structure by enabling them to feel the difficult-to-visualize forces.

Simulating protein motions with rigidity analysis

TL;DR: A novel method based on rigidity theory to sample conformation space more effectively is proposed and extensions of the framework to automate the process and to map transitions between specified conformations are described.

Probabilistic roadmaps for path planning in high-dimensional configuration spaces

TL;DR: Experimental results show that path planning can be done in a fraction of a second on a contemporary workstation (/spl ap/150 MIPS), after learning for relatively short periods of time (a few dozen seconds).

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.
