Abstract A strategy for navigation-type collective behaviour learning is developed for swarm robotic coordination in a target search task. Sub-swarms are formed by utilizing the method of dynamic self-organizing task allocation with closed-loop adjusting function, and then a social learning particle swarm optimization based robotic learning strategy is introduced into sub-swarms. In the sub-swarm, all robots are sorted in descending order by the cognition ability of each robot to its common desired target. The robots with better perception of the target are regarded as the behaviour demonstrators. Then, one of the behaviour demonstrators is selected randomly by each robot to learn in every dimension of the working space. Thus, the learning behaviour vector of each robot can be constructed for decision making on its future moving behaviour. The results show that the robot can coordinate with each other and the search efficiency is improved without the global social experience learning.
