Survey of Technologies for Industry 4.0

Technology is advancing day by day and with its relentless progress, the industry is also constantly evolving to meet new-age customer expectations with higher efficiency and sustainability. Automation and robots existed during industry 3.0 as well but now they are being connected in networks for the ease of managing, monitoring and controlling the manufacturing plants. Online / remote location based control and machine to machine communications are but few of the infinite possibilities opened up in the fourth industrial revolution. Industry 4.0 doesn't refer to a single technology/process, rather it is a seamless physical-digital integration of multiple cutting edge technologies. This paper presents a short survey covering important industry 4.0 technologies such as autonomous mobile robots (AMR), internet of robotic things (IoRT), block chain, artificial intelligence (AI), cyber security, big data analytics and machine learning (ML). This paper also presents important research scopes and directions identified for each of these technologies towards wider implementations of industry 4.0 architectures.
