Technological progress and specific of the modern consumer market forces the use of more and more advanced solutions in the field of automation and robotics.
The increase of pace of automatization and robotization in the near future will definitely result in increase of the demand for IT specialists, programmers, manufacturing engineers and less skilled technicians.
New training systems using the concept of mobile learning using advanced means of communication using more and more popular portable devices like smartphones and tablets should significantly shorten training time and provide a reasonable level of cost.
The new modules will be created with: equipment manufacturers manuals, materials supplied by production engineers, materials created by the managers and other and will automatically be adapted to be used in the production line of machines and systems.
The developed solution offered a number of communication functionalities for participants including access to forums, dictionaries, web resources, chats, and more.
