Apart from the conventional manual manufacturing process these automated techniques plays a vital role in performing repetitive tasks and their by increases the productivity levels.

Here in this paper we particularly concentrate on the aspects like implementation and the applications of these industrial manipulators with its future enhancements.

Introduction of robotics:

Robotics is nothing but the science and technology which deals with the design, construction and implementation of multi functional manipulating electro mechanical devices which can perform tasks repeatedly.

What is automation:

The science dealt in the manufacturing of self acting and self moving machines i.e. development of the sequential program which can access the electro mechanical devices effectively.

Different kinds of automation:

Till now automation is classified as three types firstly fixed automation secondly flexible automation and finally programmable automation.

  • Fixed automation- adopted in bulk productivity areas where an efficient and constant high production rate is required i.e. nuts and bolts manufacturing.
  • Flexible automation – whenever there is a requirement of variations in the production of the components flexible automation is implicated i.e. manufacturing of nuts and bolts of different kinds.
  • Programmable automation – an program of instruction where made in the areas where there is a need of variety of products of lesser quantity with greater flexibility.

10 Gigabit Ethernet Seminar



LAN forms basis for all fields like commercial, can be research and even data communication. But the present application asks for higher bandwidth so that huge data is sent. Ethernet which is a cost-effective technology is being used for all local area networks. For high speed a transmission medium called coaxial cable is used along with repeaters. And using transceivers around 250 machines can be attached via transceivers. So that maximum speed can be obtained. Optical Ethernet is a technology which helps Ethernet to extend LAN into MANS AND WANS. Where the usage of Ethernet LAN is mostly in enterprise applications where as optical Ethernet is providing service I.e. it is responsible for delivery of data on time to different users based on their requirement.


The data is sent via frames. An Ethernet frame consists of the fields with minimum packet size and maximum packet size, both source and destinations address, and also a protocol-type field. And the address fields needs to be globally unique. i.e. Ethernet is simple technology. Ethernet supports IP traffic as IP and Ethernet together and Optical Ethernet supports all types of applications it can be either voice applications or data applications.

Conclusion: We can conclude that Ethernet which is a cost-effective technology is being used for all local area networks. For high speed a transmission medium called coaxial cable is used along with repeaters.

Low Power Design in VLSI ECE Presentation PPT

Introduction to Low Power Design in VLSI ECE Presentation:

The electronics industry has achieved a consistent growth over two decades mostly to the advances in integration technologies and large-scale systems design – i.e. due to the advent of VLSI. The number of applications based on integrated circuits resulted in high-performance computing, telecommunications, and consumer electronics has been increasing. In this paper we discuss about VLSI, its design styles and its design cycle.

One of the most important characteristics of for today’s services focuses on the higher bandwidth and also high processing power. The other characteristic which is focused more is the personalized services to the user depending on the user requirement which includes the flexibility also the mobility feature.

When we consider VLSI design styles, several design styles can be considered for chip implementation of specified algorithms. Each design style has its own advantages as well as disadvantages and thus an appropriate choice has to be made by designers in order to provide the functionality at low cost. It includes Field Programmable Gate Array an array of logic cells connected via routing channels. These cells include Special I/O cells and logic cells. When we consider that other design style which comes after FPGA is Gate Array, which is capable of processing fast. The implementation includes with the metal mask design and also processing.

The GA chip utilization factor is higher when compared to that of FPGA and in terms of speed also it is higher. One of the most custom design styles is Semi-Custom design style. All the used logic cells are developed and characterized and stored in cell library. When we consider the full custom design, the mask design implemented without the usage of the library.

Electrical Seminar Topic on Transformers

Wound magnetic devices are designed to transfer of energy over a wide frequency range. Usually broadband transformers are wound on ferrite rods and threads. This is used in the equipment of Telecomm. Binocular cores and Balun are used for broadband transformers and it must accommodate RF power.

Conventional and transmission-line types are the two kinds of transformers:

The former type allows transformation ratio that we usually need

The latter comes with parallel or twisted wingdings that helps to produce a specific interface of transformations like 16:1 and 4:1 and 9:1.

For determining the Minimum- Number – of – Turns impedance ratio square root is used. The primary resistance is around 5 times the impedance. A resistance of 1000 ohms is allowed with a 200 ohm to 50 ohm transformer and it needs inductance of 88 uh.

Ferrites are used for Balun cores. The core material permeability is usually around 850 to 900. It is designed by placing two thirds of far-right side by side. Quick setting epoxy is used to glue cores together to create separate toroid tubes of two.

Usually frequency based broadband transformers have medium or low level of frequency. Fair-Rite 78 or 77 materials are examples of manganese zinc ferrites and they are very ideal. In order to reduce the Rdc ratio core geometry be used. For a high level of frequency Nicke zinc ferrites are used as the core materials. The band pass lies above 500 kHz.

For active mixer broadband transformers are used as output. For matching an antenna of 50 ohms to a grounded gate an amplifier is used to receive and convert. Two broadband transformers are used in push-pull RF power amplifier.

Transformers can also be created for providing DC isolation. Matching of impedance and specific voltage and current ratios. It provides coverage of 1.8 to 30 MHz and have an efficiency of 90% range.
