Geometric Learning and Topological Inference with Biobotic Networks: Convergence Analysis [article]

Alireza Dirafzoon, Alper Bozkurt, Edgar Lobaton
2016 arXiv   pre-print
We consider agents mimicking motion behaviors of cyborg insects, known as biobots, and exploit coordinate-free local interactions among them to infer geometric and topological information about the environment  ...  In this study, we present and analyze a framework for geometric and topological estimation for mapping of unknown environments.  ...  CONCLUSION AND FUTURE WORK We presented a framework for geometric-topological learning of unknown environments using local interactions amongst the agents in biobotic networks.  ...

Dynamic Topological Mapping with Biobotic Swarms [article]

Alireza Dirafzoon and Alper Bozkurt and Edgar Lobaton
2015 arXiv   pre-print
In this paper, we present an approach for dynamic exploration and mapping of unknown environments using a swarm of biobotic sensing agents, with a stochastic natural motion model and a leading agent (e.g  ...  These maps are then merged into a global topological map which can be visualized using a graphical representation that integrates geometric as well as topological feature of the environment.  ...  To proceed with the geometric point cloud reconstruction, we follow the Isometric mapping (Isomap) technique [37] in manifold learning [38] .  ...

Topological mapping of unknown environments using an unlocalized robotic swarm

Alireza Dirafzoon, Edgar Lobaton
2013 2013 IEEE/RSJ International Conference on Intelligent Robots and Systems  
In this paper, we explore how stochastic motion models and weak encounter information can be exploited to learn topological information about an unknown environment.  ...  We employ tools from algebraic topology to extract spatial information of the environment based on neighbor to neighbor interactions among the biologically inspired agents with no need for localization  ...  Algebraic topology, in contrary to geometric techniques, which aim to estimate shapes and distances, deals with the way that objects are connected.  ...

Robust Topological Feature Extraction for Mapping of Environments using Bio-Inspired Sensor Networks [article]

Alireza Dirafzoon, Edgar Lobaton
2014 arXiv   pre-print
In this paper, we exploit minimal sensing information gathered from biologically inspired sensor networks to perform exploration and mapping in an unknown environment.  ...  Furthermore, various strategies for defining encounter metrics with different degrees of information regarding agents' motion are suggested to enhance the precision of the estimation and classification  ...  Hence, methods from machine learning and statistical data analysis recently have been integrated with persistence analysis in order to make inference and interpretation out of such intervals [15, 16]  ...
