Advances in robotics liberated robots from factory floors by the end of 20th century. Use of robots in our daily lives is only expected to increase in time. Robots, while relieving us from the burden of tedious, hard and dangerous tasks, most of them are still expected to be territorial, i.e. they will operate in a predefined or rather bounded environment. For enhanced performance, a robot should be familiar with its territory. In this work, use of skylines extracted from panoramic images is studied in order to provide localization in a square region. In order to achieve localization in a specific territory, firstly, a map is formed in that area using skylines which are extracted from captured photographs. Then, different images are obtained in the territory and skyline signals are extracted for the purpose of matching with the ones of map. As a result of matching process, localization is performed in that certain territory. In order to observe performance of localization algorithm, photographs are captured in diferent environments, seasons and times of day. Also, artifical occlusions are added to skyline signals in order to observe failure point of algorithm.

Localization for mobile robots using skyline in panoramic images Koku, Ahmet Buğra (Journal of the Faculty of Engineering and Architecture of Gazi University, 2019-01-01) Advances in robotics liberated robots from factory floors by the end of 20th century. Use of robots in our daily lives is only expected to increase in time. Robots, while relieving us of the burden of tedious, hard and dangerous tasks, most of them are still expected to be territorial, i.e. they will operate in a predefined or rather bounded environment. For enhanced performance, a robot should be familiar with its territory. In this work, use of skylines extracted from panoramic images is studied in order ...
Hybrid model based on energy and experimental methods for parallel hexapod-robotic light abrasive grinding operations Latifinavid, Masoud; Konukseven, Erhan İlhan (2017-12-01) Automatic grinding using robot manipulators requires simultaneous control of the robot endpoint and force interaction between the robot and the constraint surface. In robotic grinding, surface quality can be increased by accurate estimation of grinding forces where significant tool and workpiece deflection occurs. The small diameter of the tool causes different behavior in the grinding process in comparison with the tools that are used by universal grinding machines. In this study, we develop a robotic surf...
Perpetual Robot Swarm: Long-Term Autonomy of Mobile Robots Using On-the-fly Inductive Charging Arvin, Farshad; Watson, Simon; Turgut, Ali Emre; Espinosa, Jose; Krajnik, Tomas; Lennox, Barry (2018-12-01) Swarm robotics studies the intelligent collective behaviour emerging from long-term interactions of large number of simple robots. However, maintaining a large number of robots operational for long time periods requires significant battery capacity, which is an issue for small robots. Therefore, re-charging systems such as automated battery-swapping stations have been implemented. These systems require that the robots interrupt, albeit shortly, their activity, which influences the swarm behaviour. In this p...
Cooperative Pollution Source Exploration and Cleanup with a Bio-inspired Swarm Robot Aggregation Sadeghi Amjadi, Arash; Raoufi, Mohsen; Turgut, Ali Emre; Broughton, George; Krajník, Tomáš; Arvin, Farshad (2021-01-01) Using robots for exploration of extreme and hazardous environments has the potential to significantly improve human safety. For example, robotic solutions can be deployed to find the source of a chemical leakage and clean the contaminated area. This paper demonstrates a proof-of-concept bio-inspired exploration method using a swarm robotic system based on a combination of two bio-inspired behaviors: aggregation, and pheromone tracking. The main idea of the work presented is to follow pheromone trails to fin...
Locomotion Gait Optimization For Modular Robots; Coevolving Morphology and Control Pouya, Soha; Aydın Göl, Ebru; Moeckel, Rico; Ijspeert, Auke Jan (2011-01-01) This study aims at providing a control-learning framework capable of generating optimal locomotion patterns for the modular robots. The key ideas are firstly to provide a generic control structure that can be well-adapted for the different morphologies and secondly to exploit and coevolve both morphology and control aspects. A generic framework combining robot morphology, control and environment and on the top of them optimization and evolutionary algorithms are presented. The details of the components and ...
