This paper describes a framework for machine cooperation and interaction designed to promote collaborative work with humans in a natural and flexible manner. More specifically, we propose a system where all the interactions with the robots are achieved through voice using Alexa Voice Service (AVS). Besides the implementation of a voice interface channel, we develop a navigation module that enables a robot to autonomously navigate through a map to reach a specific destination while avoiding obstacles. We provide the system with the ability to choose and operate the appropriate robot in context of multi-robot cooperation for task achievement. In addition, a user can intervene during the process of executing a relatively complex task by interacting with the robots via voice commands. To validate the proposed framework, we conduct experiments to quantify the performance during cooperative action involving the human and the system.
