In this paper, we study the problem of collective and emergent sensing with a flying robot swarm in which social interactions among individuals lead to following the gradient of a scalar field in the environment without the need of any gradient sensing capability. We proposed two methods-desired distance modulation and speed modulation-with and without alignment control. In the former, individuals modulate their desired distance to their neighbors and in the latter, they modulate their speed depending on the social interactions with their neighbors and measurements from the environment. Methods are systematically tested using two metrics with different scalar field models, swarm sizes and swarm densities. Experiments are conducted using: (1) a kinematic simulator, (2) a physics-based simulator, and (3) real nano-drone swarm. Results show that using the proposed methods, a swarm-composed of individuals lacking gradient sensing ability-is able to follow the gradient in a scalar field successfully. Results show that when individuals modulate their desired distances, alignment control is not needed but it still increases the performance. However, when individuals modulate their speed, alignment control is needed for collective motion. Real nano-drone experiments reveal that the proposed methods are applicable in real-life scenarios.

A self-organized collective foraging method using a robot swarm Karagüzel, Tugay Alperen; Turgut, Ali Emre; Department of Mechanical Engineering (2020) In this thesis, a collective foraging method for a swarm of aerial robots is investigated. The method is constructed by using algorithms that are designed to work in a distributed manner, by using only local information. No member in the swarm has access to global information about positions, states or environment. The environment, that robots are planned to operate in, contains a virtual scalar field which consists of grids containing constant values. The grid values indicate desired regions of the environ...
A generative model for multi class object recognition and detection Ulusoy, İlkay (2006-01-01) In this study, a generative type probabilistic model is proposed for object recognition. This model is trained by weakly labelled images and performs classification and detection at the same time. When test on highly challenging data sets, the model performs good for both tasks (classification and detection).
Self-organized Collective Motion with a Simulated Real Robot Swarm Raoufi, Mohsen; Turgut, Ali Emre; Arvin, Farshad (2019-07-01) Collective motion is one of the most fascinating phenomena observed in nature. In the last decade, it aroused so much attention in physics, control and robotics fields. In particular, many studies have been done in swarm robotics related to collective motion, also called flocking. In most of these studies, robots use orientation and proximity of their neighbors to achieve collective motion. In such an approach, one of the biggest problems is to measure orientation information using on-board sensors. In most...
Self-organised Flocking of Robotic Swarm in Cluttered Environments Liu, Zheyu; Turgut, Ali Emre; Lennox, Barry; Arvin, Farshad (2021-01-01) Self-organised flocking behaviour, an emergent collective motion, appears in various physical and biological systems. It has been widely utilised to guide the swarm robotic system in different applications. In this paper, we developed a self-organised flocking mechanism for the homogeneous robotic swarm, which can achieve the collective motion with obstacle avoidance in a cluttered environment. The proposed mechanism introduces an obstacle avoidance approach to the Active Elastic Sheet model that was previo...
Toward automated cell model development through information theory Sayyed-Ahmad, A; Tuncay, Kağan; Ortoleva, PJ (American Chemical Society (ACS), 2003-12-11) The objective of this paper is to present a methodology for developing and calibrating models of complex reaction/transport systems. In particular, the complex network of biochemical reaction/transport processes and their spatial organization make the development of a predictive model of a living cell a grand challenge for the 21st century. However, advances in reaction/transport modeling and the exponentially growing databases of genomic, proteomic, metabolic, and bioelectric data make cell modeling feasib...
