Autonomous Exploration For Navigating In MDPs

چکیده
While intrinsically motivated learning agents hold considerable promise to overcome limitations of more supervised learning systems, quantitative evaluation and theoretical analysis of such agents are difficult. We propose to consider a restricted setting for autonomous learning where systematic evaluation of learning performance is possible. In this setting the agent needs to learn to navigate in a Markov Decision Process where extrinsic rewards are not present or are ignored. We present a learning algorithm for this scenario and evaluate it by the amount of exploration it uses to learn the environment.

متن کاملDistributed Value Functions for Multi-Robot Exploration: a Position Paper
This paper addresses the problem of exploring an unknown area with a team of autonomous robots using decentralized decision making techniques. The localization aspect is not considered and it is assumed the robots share their positions and have access to a map updated with all explored areas. A key problem is then the coordination of decentralized decision processes: each individual robot must ...
متن کاملA frontier-based approach for autonomous exploration
We introduce a new approach for exploration based on the concept of frontiers, regions on the boundary between open space and unexplored space. By moving to new frontiers, a mobile robot can extend its map into new territory until the entire environment has been explored. We describe a method for detecting frontiers in evidence grids and navigating to these frontiers. We also introduce a techni...

This paper provides an overview of a three year project conducted on the subject of self-localisation and autonomous navigation by a mobile robot. The research was carried out in two stages: Self-Localisation. Due to the fundamental unreliability of dead reckoning, landmark-based methods were investigated. Several related issues were addressed, including performance evaluation, replication and ...
متن کاملPG2P: a perception-guided path planning approach for long range autonomous navigation in unknown natural environments
This paper presents a new hybrid path planning approach for autonomous robots navigating in natural unknown environments. The main purpose is to consider perception planning and path planning in a single unified process, so that the most relevant perception can be performed considering the current goal of the robot. We consider this approach as a way to fill the gap between navigation tasks and...
