Robots with lights is a model of autonomous mobile computational entties operating in the plane in Look-Compute-Move cycles: each agent has an externally visible light which can assume colors from a fixed set; the lights are persistent (i.e., the color is not erased at the end of a cycle), but otherwise the agents are oblivious. The investigation of(More)
Consider a finite set of identical computational entities that can move freely in the Eu-clidean plane operating in Look-Compute-Move cycles. Let p(t) denote the location of entity p at time t; entity p can see entity q at time t if at that time no other entity lies on the line segment p(t)q(t). We consider the basic problem called Mutual Visibility:(More)
Studies on soil quality of mangrove forests would be of immense use in minimizing soil degradation and in adopting strategies for soil management at degraded sites. Among the various parameters of soil quality, biological and biochemical soil properties are very sensitive to environmental stress and provide rapid and accurate estimates on changes in quality(More)
This paper proposes a distributed algorithm for circle formation by multiple autonomous mobile robots with limited visibility. Each robot sees up to a fixed distance around it and moves to a new position. Eventually they form a circle of a given radius. The robots do not store past actions. The robots are anonymous and cannot be distinguished by their(More)
This paper proposes a distributed algorithm for circle formation by a system of mobile robots. Each robot observes the positions of other robots and moves to a new position. Eventually they form a circle. The robots do not store past actions. They are anonymous and cannot be distinguished by their appearance and do not have a common coordinate system(More)
The traditional distributed model of autonomous, homogeneous , mobile point robots usually assumes that the robots do not create any visual obstruction for the other robots, i.e., the robots are see through. In this paper, we consider a slightly more realistic model, by incorporating the notion of obstructed visibility (i.e., robots are not see through) for(More)
