Title:Cooperative tasks need versatile inter-robot communication systems ?
Date: 1998
Abstract:The aim of this project is to investigate the advantages and drawbacks of using communications between physical agents, such as mobile robots, while performing a common task. The task is performed by a set of LEGO robots inside an arena, of which a small area is designated the nest, with some polystyrene targets dispersed about the rest of it. The task is to collect the targets and bring them to the nest. The robots are provided with a radicommunication unit which allows them to communicate with each other.Two different experiments are done. The first one consists of the robots performing the designed task without communication between them, that is, as a collective behaviour task. The second one consists of the same task but performed in a cooperative way, that is, using the communication units to share information relevant to the task.Performance of the robots was compared and it was found that increasing the number of robots improved the results obtained for both tasks. The cooperative task was significantly better than the collective task in all the cases tested.
