Can agent be autonomous without having consciousness?
Here is a glimpse.

Concerning agents you're trying to elaborate here,I would like to give you some insights of these following key aspects,which might help in your future research nor knowledge;


Consciousness
Here an agent is capable of understanding its own existence nor selfawareness.
Intelligence
An agent is capable solving problem based reasoning with no help from third-party knowledge.
Autonomous
An agent has the ability to solve problems basing on the third-party knowledge for instance,self driving car does its own problem solving basing on the existing knowledge it discovers from the environment.



  Therefore,for any agent to be autonomous,it doesn't mean its selfaware
  or conscious,otherwise. For your information,do further reading on the
  above three terminologies.
