Mobile robot navigation in dynamic environments
Service robots which act in environments populated by humans have <br>become very popular in the last few years. A variety of systems exists <br>which act for example in hospitals, office buildings, department <br>stores, and museums. Furthermore, several multi-robot systems have <br>been developed …

Robot Planning in Uncertain, Dynamic Environments
… applications require robots to operate in dynamic environments characterized by moving objects or agents whose trajectories are unpredictable. This thesis addresses the challenges posed by such environments by introducing Relative Temporal Probabilistic Roadmaps (Rel-T-PRM), a novel motion …

Decentralized task allocation for dynamic environments
… which slowed convergence in decentralized environments. The second form was called the Consensus Based Bundle Algorithm (CBBA). CBBA required significantly fewer iterations than SGA but it is noted that both still rely on global synchronization mechanisms. These synchronization mechanisms …

Neural Mechanisms For Learning In Dynamic Environments
… the neural mechanisms for learning in dynamic environments. In dynamic environments, where the underlying state of the environment can change, inferring the current state of the environment is important to guide adaptive behavior. People should maintain their beliefs about the …

Path manipulation strategies for rendering dynamic environments.
The current work introduces path manipulation as a tool that extends bidirectional path tracing to reuse paths in the temporal domain. Defined as an apparatus of sampling and reuse strategies, path manipulation reconstructs the subpaths that compose the light transport paths and addresses the …

Long-term robot mapping in dynamic environments
… that can construct a map of an initially unknown dynamic environment. This is often referred to as the Simultaneous Localization and Mapping (SLAM) problem. A number of approaches to the SLAM problem have been successfully developed and applied, particularly to a mobile robot constructing a map of …

Trajectory Planning for Flights in Multiagent and Dynamic Environments
… Aerial Vehicles), a 3D real-time planner for environments with static obstacles, dynamic obstacles, and other planning agents still remains an open problem. The dynamic nature of these environments demands high replanning rates, making this problem especially hard on computationally limited …

Theoretical Foundations for Learning in Games and Dynamic Environments
… state of the environment, which is modeled as dynamic. Thus, we need efficient algorithms for learning good policies, which tell the agent what to do as a function of the environment’s state. Extensive work spanning multiple domains such as economics, computer science, and statistics has been …

Real-time intelligent behaviour in dynamic environments : soccer-playing robots
An autonomous robot operating in a dynamic environment is confronted by the question of, "What to do now?" The problem of designing a controller for a car-like robot competing with another robot in a game of soccer is considered. This is a dynamic environment; the locations of the ball and the …
