As physical and digital worlds are merging it is changing the dynamics of the industries in India. The German Academy of Science and Technology coined the term fourth industrial revolution (Industry 4.0) changing the industrial process dramatically with automation and robotic technology at rising. With the advancement of robotics technology, the complexities are also increasing which has led to the development of one of the strong arms of the technologies of the industrial revolution- Swarm- robotics. Swarm intelligence take its inspiration from social animals and display the concept of collective behavior. With simple hardware architecture, high feasibility, cost efficiency, robustness; it comes out as a very user-friendly technology which is fit for the industrial applications where depending on a single robot for the accomplishment of a task is not possible. The only challenge this multi-robot technology faces is to establish an efficient communication system between them to ensure proper coordination, communication, and routing. Zigbee technology was thus proposed as a solution as it fits perfectly with the features of swarm robotics and improves the efficiency of the mobile robots.
