1. INTRODUCTION

The general concept of intelligent equipments and advanced robotics, brings into the structure, systems and sub-systems MEMS and MECHATRONIC/ MICROMECHATRONIC identified by experimental and behavioral structure simulation, functioning and maintenance and by results of measured signals and mathematical and physical models, but also through destination of applications which will take into account the process or product type from geometrical and precision characteristics, of nature and properties of the materials used, of technical and technological parameters and of process accessibility methods (Dumitriu, 2006).

The general and inovative concept of intelligent equipments and advanced robotics, is realized considering elements structure, components and functional compatibility, that enter in automatization and informatization chart of the ensemble, and depending on micro-movements obtaining, micro-positionings and micro-measurements in coordination, command, control and decision in expert matrix (Gheorghe, 2006).

The concept of intelligent equipments and advanced robotics, integrates the architecture of sensors and micro-sensors in value chain of signal generation and information transfer, actuators and micro-actuators architecture in mobility chain of ensemble (Suzumori, 1991), architecture of electronic and micro-electronic units in signals processing chain, controllers architecture in command chain and coordination process automated and informatized, architecture of process computers in driving process and architecture of software packages in movement chain, measurement, integrated and decisional control, commands, coordination, driving, visualization results, static status monitoring and dynamic status (Brugger, 1993).

2. INTEGRATION OF INTELLIGENT EQUIPMENTS AND ADVANCED ROBOTICS

The intelligent equipments and advanced robotics, have been realized and implemented by author and also in some high-tech level companies.

An example of realized advanced robotics, is "the concept of mecatronic micro-robot of measurement and dimensional integrated control with five degree liberty with micro-detector with Laser fascicle", used in metrological and industrial measurement processes, from integrating industry of precision mechanics and mechatronics and showed in the figure 1:

[FIGURE 1 OMITTED]

The constructive mechatronic solutions of the equipment and means of sensors / transducers architecture integration are presented in the figure 2 (Fatikow, 1997):

Functional chart of mecatronic micro-robot of measurement and dimensional integrated control is showed in the figure 3:

3. EXPERIMENTAL DATA AND RESULT REGARDING INTELLIGENT EQUIPMENTS AND ADVANCED ROBOTICS

3.1 Applications and comparison areas of actuators / micro-actuators used at intelligent equipments and advanced robotics

From the laboratory experimentations performed can be synthesize diagrams that realize comparisons between different actuators as: electrical micro-engines and step by step micro-engines, microelectromagnets, piezoelectric micro-actuators, pneumatic and hydraulic micro-cylinders etc.

So, in the figure 4, there is synthesized the maximum speed of the micro-actuators and comparison speed-force:

[FIGURE 4 OMITTED]

In the figure 5 is synthesized positioning time for controlled response operating.

3.2 Measurement of deviation from the roundness and / or from rugosity

In the figure 6, there are presented the results of realised measurement in laboratory, of roundness deviation and rugosity, using an intelligent equipment with Laser detector:

4. CONCLUSION

In perspective, intelligent equipments technique and advanced robotics, will develop new methods and mechatronics and nano-mechatronics methodologies which will control at total quality level of industrial products and of manufacturing processes, contributing in this way to increasing competitiveness on national, European and international level.
