چکیده
The design and implementation of theoretically-sound robot motion planning algorithms is challenging. Within the framework resolution-exact algorithms, it possible to exploit soft predicates for collision detection. a balancing act between easily implementable their accuracy/effectivity. In this paper, we focus on class planar polygonal rigid robots with arbitrarily complex geometry. We remarkable decomposability property collision-detection such robots. introduce general technique produce decomposition. If an m-gon, complexity approach scales linearly in m. This contrasts O(m^3) known exact planners. It follows that can now routinely any robot. results planners within Soft Subdivision Search (SSS) framework. significant advancement theory sound complete implemented decomposed our open-source Core Library. experiments show are effective, perform real time non-trivial environments, outperform many sampling-based methods.

Soft Subdivision Search in Motion Planning
The main paradigm for practical motion planning in the last two decades is Probabilistic Road Map (PRM). We propose an alternative paradigm called Soft Subdivision Search (SSS). The SSS approach is based on two ingredients: the standard subdivision of space, coupled with soft predicates. Such predicates are conservative and convergent relative to exact predicates. This leads to a new class of r...
متن کاملPath Planning for Simple Robots using Soft Subdivision Search
The concept of ε-exact path planning is a theoretically sound alternative to the standard exact algorithms, and provides much stronger guarantees than probabilistic or sampling algorithms. It opens the way for the introduction of soft predicates in the context of subdivision algorithm. Taking a leaf from the great success of the Probabilistic Road Map (PRM) framework, we formulate an analogous ...
متن کاملSoft Subdivision Search in Motion Planning, II: Axiomatics
We propose to design motion planning algorithms with a strong form of resolution completeness, called resolution-exactness. Such planners can be implemented using soft predicates within the subdivision paradigm. The advantage of softness is that we avoid the Zero problem and other issues of exact computation. Soft Subdivision Search (SSS) is an algorithmic framework for such planners. There are...

Humanoid robotics hardware and control techniques have advanced rapidly during the last five years. Presently, several companies are developing commercial prototype full-body humanoid robots. This humanoid technology will contribute to the development of sophisticated prostheses in the medical field, as well as human augmentation systems on the military battlefield. In order to improve the auto...
متن کاملMotion Planning for Legged Robots
Slide 0 In this talk, we present a general trajectory generation scheme for a class of " kinematic " legged robots. The method does not depend upon the number of legs, nor is it based on foot placement concepts. Instead, our method is based on an extension of a nonlinear trajectory generation algorithm for smooth systems to the legged case, where the relevant mechanics are not smooth. Our exten...
