Optimal Exclusive Perpetual Grid Exploration by Luminous Myopic Opaque Robots with Common Chirality

Quentin Bramas, Pascal Lafourcade, Stéphane Devismes
2020 International Conference on Distributed Computing and Networking 2021  
We consider swarms of luminous myopic opaque robots that run in synchronous Look-Compute-Move cycles. These robots have no global compass, but agree on a common chirality.  ...  In this context, we propose optimal solutions to the perpetual exploration of a finite grid.  ...  We investigate optimal solutions to the exclusive Perpetual Finite Grid Exploration (PFGE) in synchronous settings using luminous myopic opaque robots.  ...

Terminating grid exploration with myopic luminous robots [article]

Shota Nagahama, Fukuhito Ooshita, Michiko Inoue
2021 arXiv   pre-print
We investigate the terminating grid exploration for autonomous myopic luminous robots.  ...  First, we prove that, in the semi-synchronous and asynchronous models, three myopic robots are necessary to achieve the terminating grid exploration if the visible distance is one.  ...  [5] also studied the perpetual exploration of a (finite) grid with myopic luminous and non-luminous robots in the FSYNC model on the assumption that robots agree on a common chirality.  ...

Finding Water on Poleless Using Melomaniac Myopic Chameleon Robots

Quentin Bramas, Pascal Lafourcade, Stéphane Devismes, Ryuhei Uehara, Giuseppe Prencipe, Martin Farach-Colton
2020 Fun with Algorithms  
To address this problem, we investigate optimal (w.r.t., visibility range and number of used colors) solutions to the infinite grid exploration problem (IGE) by a small team of M2C robots.  ...  A new generation of autonomous mobile robots, called M2C (for Melomaniac Myopic Chameleon), have been designed to find water on Poleless.  ...  The exclusive perpetual exploration of a finite grid is considered in the same model in [3] .  ...
