VIRTUAL TRAINING STATION

[:en]Proxicad srl in 2016 has carried out R & D activities aimed at developing and acquiring new knowledge about Reality Virtule. Virtual Reality, with its “Immersive Environments”, offers a powerful design tool, and adds impossible potentials to the most advanced traditional tools (CAD, CAM, CAE). In particular, it has developed a unique know-how aimed at supporting industrial manufacturers in replacing physical prototypes with virtual prototypes through virtual reproduction of manufacturing, assembling, and testing processes. Virtual prototyping responds to the growing demand for smart and stand-alone products assisting industrial manufacturers in their digital transformation process.
Currently, in the field of prototyping, Cave Automatic Virtual Environment (Cave) is used, consisting of a projection chamber consisting of three to six screens on which the environments created by the machine are re-projected and position sensors detect and transmit position and user movements.
However, that Virtual Prototyping system is present
• Lower dive (and still connected to the user) and 3D perception
• Very limited range of movements
• No portability of the equipment
• High costs
With this project we wanted to implement this technology by trying to overcome its limitations and criticalities. I’m part of a simpler outfit, which is mainly designed for the installation, and using the various software tools we have developed a new one to design a product from its design to assembly and maintenance. The designer finally makes use of three-dimensional stereographic visualization and an intuitive and effective interface without having problems with the use of the classic Cave.
The features of our system are:
• 3D Motion range limited or unlimited
• Unlimited portability of the equipment
• Low costs
• High sensation of immersion and three-dimensional perception
The human-computer interaction is so radically improved, opening scenarios described in the past only by science fiction.
Within mechanical engineering, it was possible to evaluate the assemblies at a distance and collaboratively through the Internet network, also sharing the libraries of parts already modeling in 3D.
There is also the possibility for the observer to manipulate and modify objects in the virtual scenario interactively, or during the work session.

In “Virtual Prototyping” modeling takes place at a traditional location and the model is exported to create assembly tests and bulk tests in a virtual environment. In these sessions, the designer develops, using advanced tracking and visualization systems, the work begun in the 3D CAD environment, controlling any interference and
malfunctions, with a significant reduction in the cost of real models and prototypes.
Virtual Reality is commonly applied in military, aeronautical, and medical-surgical operations to perform simulations and training complex or dangerous operations in complete security.
In particular for this project, to highlight one of the potentialities of our technology, we have planned to build a virtual training station for the semi-automatic assembly of a television.
The mounting station is semi-automatic. The rotating table on which the product is mounted is fully automatic and is powered by a motor. All components are manually mounted and screwed, except for the TV base.
This is a station suitable for Virtual Training, to see the components assembly sequences there is a visual indicator indicating which piece to fit (the part flashes) and how to connect (the screws are pulsating).
Some components must be mounted using a manual screwdriver located to the right of the station.
