AuMac (AUtomated MAChine) is a multitask robot designed for children. Some special tasks like sound origin detection, voice recognition, robot human interactions, video conference facility and remotely operating robot anywhere from the world been implemented in this robot. This robot was made to speak depending on voice commands in such a way to communicate with the children, so it would become a best friend to them. Even their parents can look after them through robot by making a video call and can navigate robot by giving voice commands from the mobile phone to look their children. It would be useful for the doctors in this way: Generally we notice some children are not so active and suffering from autism and mental disorders. It would become tedious for the doctors to treat them as children never open up before them. Children play with toys and speak with them, they create a separate world and if the toys respond they would be much enthusiastic and be very freE. AuMac helps the doctors by communicating with the children with a preloaded tasks desired by doctors like in what way it has to communicate with them. They let children to spend with AuMac alone to make them comfortable, then doctors observe the behavior of children through video call and can easily analyze in order to cure them.
AuMac is not only limited for the children but also much useful in military and other security applications. As it is provided with 3g video conference and tasks done by voice recognition, we can operate this robot anywhere from the world and can implement tasks like navigating and operating weapon (which can be installed in the robot) by just giving voice commands. Instead of human we can send this sort of robots in some terror attacked places and save human life. The same technology can be implemented in RC helicopter and can be used for monitoring areas, providing VIP security and controlling traffic can be easily done.
AuMac is a low cost, highly efficient and low power consumption robot which performs actions accurately. It is designed based on Audrino Microcontroller Board.

The advantage of composite materials is the high stiffness-to-weight and strength-to-weight ratios. The limitation of composite materials is debonding of the reinforcement from the matrix which occur under two conditions-a weak interface and mismatch of thermal and mechanical properties between the reinforcement and the matrix leading to a buildup of residual stresses. The problems have been overcome to some extent by improving the interface problems, using better reinforcements like particulates and whiskers and minimizing the residual stresses by suitably selecting the matrix and reinforcements. One answer to overcome the limitations is to use functionally graded materials (FGM's). This paper reviews the various processing techniques of FGM's and the current research work done.- Current Challenges in High Speed Machining of Dies and Moulds the Cutting Edge Technology

With global competition picking up for supply of discrete products, shorter product life cycles, frequent design changes, quick delivery schedules, quality demands of customers and low costs. High Speed Machining (hereafter called HSM) plays a major role as one of the time compression techniques in manufacturing.Various papers have been published in the area of HSM to cater to the demanding needs of manufacturers of dies and moulds. An attempt has been made to present yet another innovative paper on the current challenges and trends In HSM of dies and moulds for the benefit of toolmakers and engineers, academicians and the engineering community at large. This paper introduces HSM technique for the novice, highlights the need for HSM, the benefits of HSM and its limitations, the application areas, the production equipment, the spindle, the CMC controls, the drive system, the programming requirements, tool path generation, cutting tools, tool holders and tool holder systems, fixturing, cutting data requirements, chatter and shock control, out- of- cut time study, metal removal fluids, product requirements, die/mould manufacturing through HSM technique and safety aspects.
