This paper introduces and discusses automata systems as a new way for formal languages processing. In the text there are four models described. The first model works on sequential mode. At one computation step only one of components works. The second one works on semi-parallel mode. At the one computation step either one or all the components of the automata system work. In the last two models each component of the automata system has its own input string. The computation step of each component is influenced by their states, or used rules. The state, or used rule of the components of automata system can block or unblock some or all automata of the system.
