Modern technology is developing faster than we think. In industry 4.0, hundreds of new products are launched daily, but the assembly unit back-end process is tedious. Product and assembly process complexity are proportional. After manufacturing, assembling workers finish the product. User manuals and technical documentation take longer and complicate simple procedures. They may be outdated. From smartphones to heavy equipment, every new product needs assembly instructions. Industry can use Augmented Reality. Product assembly using AR makes production easier. AR can guide assembly operators...

Energy is the main concern of present day. The production of electric current in a huge amount is the need of today world. There are different methods used for the production of energy like conventional and non-conventional methods. Here I will represent the non-conventional method for the production of electric current. This non-conventional method is "Footstep power generation Mechanism" here the energy will be produced by moving the human on a moving plate in which rack and pinion gear are used to convert the physical energy into mechanical energy and further they will have converted into...
