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 for asymptotically near-optimal motion planning

TL;DR: Simulations for rigid-body motion planning show that algorithms for constructing sparse roadmap spanners indeed provide small data structures and result in faster query resolution, and suggests that finite-size data structures with asymptotic near-optimality in continuous spaces may indeed exist.

Decomposition-based motion planning: a framework for real-time motion planning in high-dimensional configuration spaces

TL;DR: A novel real-time motion planning framework, called decomposition-based motion planning, is proposed, which decomposes the original planning problem into simpler sub-problems, whose successive solution empirically results in a large reduction of the overall complexity.

Measure theoretic analysis of probabilistic path planning

TL;DR: This paper presents a novel analysis of the probabilistic roadmap method (PRM) for path planning, and gives a bound on the expected number iterations of PRM required to find a path, in terms of the number of intermediate points and the probability of choosing a point from a certain set.

Toward Optimal Configuration Space Sampling

TL;DR: A new approach to multi-query samplingbased motion planning is proposed, which exploits information obtained from earlier exploration and its current state to guide exploration and significantly decreases the runtime required for motion planning.

Non-gaited humanoid locomotion planning

TL;DR: A method of iterative constraint enforcement is presented that samples feasible configurations much more quickly and uses a probabilistic, sample-based approach to compute each step.

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.
