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.

Path Planning in Changing Environments Based on “Frame” Difference

TL;DR: HDA which is a hybrid of adjacent frame difference or K-frame difference is proposed which provides enough movement information of obstacles, and leads to safe path planning and lower replanning times and higher success rate than related planners.

Computation of Approximate Solutions for Guided Sampling-Based Motion Planning of 3D Objects

TL;DR: A modification of the iterative guiding process to avoid a situation where the part of the guiding path is too close to obstacles of the configuration space, which requires to estimate the surface of the obstacle region, which is achieved by detecting its boundary configurations during the sampling process.

The Impact of Approximate Methods on Local Learning in Motion Planning

TL;DR: It is shown that the impact of noise on learning depends on how much learning needs to take place given the topology of the environment, and a correlation between heterogeneity and the need for learning over a local region is demonstrated.

Fast Convergence RRT for asymptotically-optimal Motion Planning

TL;DR: Experimental results indicate that FCRRT significantly improves the exploration rate and success rate, and finds paths of a similar quality much more quickly compared to RRT*.
