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.

HPRM: a hierarchical PRM

TL;DR: A hierarchical variant of the probabilistic roadmap method for motion planning is introduced, by recursively refining an initially sparse sampling in neighborhoods of the obstacle boundary, that generates a smaller roadmap that is more likely to find narrow passages than uniform sampling.

Perception‐aware autonomous mast motion planning for planetary exploration rovers

TL;DR: In this paper, the authors use the ability of the rover to actively steer the visual sensor to improve fault tolerance and maximize the perception performance, which is accomplished by an online assessment of possible trajectories using synthetic, future camera views created from previous observations.

Efficient Penetration Depth Computation Between Rigid Models Using Contact Space Propagation Sampling

TL;DR: In this article, the authors proposed a novel method to compute the approximate global penetration depth (PD) between two nonconvex geometric models, which consists of two phases: offline precomputation and run-time queries.

Structural improvement filtering strategy for PRM

TL;DR: This work introduces a filtering strategy for the Probabilistic Roadmap Methods (PRM) with the aim to improve roadmap construction performance by selecting only the samples that are likely to produce roadmap structure improvement.

VIZMO++: a visualization, authoring, and educational tool for motion planning

TL;DR: An interactive tool for visualizing and editing motion planning environments, problem instances, and their solutions that is specialized for sampling-based randomized planners such as probabilistic roadmap (PRM) and rapidly-exploring random tree (RRT) methods is presented.

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).

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.
