moreThe aim of the review is to present easily readable and understandable integrated basic information on industrial robots for ready availability and consultation by concerned students, researchers, manufacturers, careerists, and potential users who lack basic knowledge of the robots and need resources to better the knowledge. The review covers applications, advantages, challenges, structural components, types, and leading manufacturers of industrial robots. The review importantly shows that industrial robots are made in various types that can be exploited to reliably improve productivity, quality, safety, and flexibility in manufacturing processing which cannot be realized with the conventional fixed automation structure. The review also shows that industrial robots have far more advantages than disadvantages and they are increasingly used in many industries such as automotive, electrical and electronics, and metals and machinery to replace manual labor in typical manufacturing processes such as packaging and labeling, soldering, welding, painting and spraying, picking and placing, assembling, disassembling, inspection and testing, dispensing, palletizing, etc. One important finding from the review is that, usage extents of industrial robots in different industries and countries are highly correlated to industrial and national productivity output levels across the globe and there is remarkable difference in industrial productivities and economies of developing countries especially African countries where the robots are hardly used and their counterparts where the robots are used considerably in industries. The paper contributes to knowledge about industrial robots, as state-of-art automation structural systems that are crucial for manufacturing in any industry or economy that wants much greater advantages and global competitiveness in our today's era of complex industrial processing.
