A robust MAS coordination mechanism for action selection -------------------------------------------------------- In this paper we present a novel approach to coordinate a group of agents controlling a robot navigation system. The approach is based on a bidding mechanism for action selection. The novelty lies in the fact that agents cooperate in determining the socially preferred action by bidding depending on the agent's view of the task to perform. An agent with a global view of the task bids based on its marginal benefit of the action, whereas an agent with a local view bids based on the marginal cost of the action.
