Abstract

Multi-robots stand out for their flexibility, scalability, and robustness in complex tasks by collaborating. Rather than a single robot undertaking a task, many robots can perform one or more tasks, which increases the task efficiency. Mobile robots require path planning to reach the targeted locations while working in areas such as service, logistics, agriculture, and production. This situation is also valid for multi-robots. In this study, an advanced multi-robot path planning method adapted to the path planning of multi-robots is proposed by combining the advantageous aspects of the Grey Wolf Optimization algorithm and the Teaching and Learning Based Optimization algorithm for the path planning of multi-robots. The proposed method was compared with other algorithms. Simulations containing combinations of population numbers, robot numbers, and different environments were applied. The proposed method shows high performance compared to other methods in simulations applied to the multi-robot path-planning problem. According to the comparison results, the proposed method showed high performance in terms of parameter results, such as reaching a faster solution, closing to the target, and total fitness values used in the evaluation of the robot team.

Gri Kurt ve Öğretme-Öğrenme Tabanlı Optimizasyona Dayalı Gelişmiş Çoklu-Robot Yol Planlaması

Abstract

Çoklu robotlar, işbirliği yaparak karmaşık görevlerde esneklik, ölçeklenebilirlik ve gürbüzlük özellikleriyle ön plana çıkmaktadır. Tek bir robotun bir görevi üstlenmesinden ziyade birçok robot bir veya birden fazla görevi üstlenebilir ve bu durum görev verimliliğini artırmaktadır. Mobil robotların servis, lojistik, tarım, üretim gibi alanlarda görev alırken hedeflenen konumlara gidebilmeleri için bir yol planlamasına ihtiyaç duyarlar. Bu durum çoklu robotlar içinde geçerlidir. Bu çalışmada Çoklu robotların yol planlaması için Gri Kurt Optimizasyonu algoritması ile Öğretme ve Öğrenme Tabanlı optimizasyon algoritmasının avantajlı yönleri birleştirilerek çoklu robotların yol planlamasına uyarlanan gelişmiş çoklu robot yol planlaması yöntemi önerilmektedir. Önerilen gri kurt optimizasyon tabanlı diğer algoritmalar ile karşılaştırılmaktadır. Popülasyon sayısı, robot sayısı ve farklı ortamlar kombinasyonlarını içeren simülasyonlar uygulanmıştır. Önerilen yöntem, çoklu robot yol planlaması probleminde uygulanan simülasyonlarda diğer yöntemlere kıyasla yüksek performans göstermektedir. Karşılaştırma sonuçlarına göre önerilen yöntem, daha hızlı çözüme ulaşma, hedefe yakınsama ve robot takımının değerlendirilmesinde kullanılan toplam uygunluk değerleri gibi parametre sonuçlarında yüksek performans göstermiştir.
