Avancées en robotique et en automatisation

The arrangement or programming of movements and groupings for a modern robot is commonly instructed by connecting the robot regulator to a PC, personal computer or (inner or Internet) organization. A robot and an assortment of machines or peripherals are alluded to as a work cell, or cell. An average cell may contain a sections feeder, an embellishment machine and a robot. The different machines are 'coordinated' and constrained by a solitary PC or PLC. How the robot associates with different machines in the cell should be modified, both concerning their situations in the cell and synchronizing with them.

Wire Arc Additive manufacturing also known as WAAM is always been economical and highly efficient technology which is very suited for producing large and complex shaped metallic components using the process of 3D printing. In past few years, it is widely studied in various fields such as automotive, marine as well as aerospace industries. As WAAM has advantage of higher metal deposition rate, lesser machining cost, higher Buy-to-fly ratio and very lesser lead time in comparison to any other powder Additive Manufacturing processes. WAAM had always been noticed topic by many of the industrial engineers and researchers. If we compare WAAM process over any other traditional manufacturing methods, considering the complex shapes and high Buy To Fly Ratio (BTF), WAAM is always proved to be best of them. Therefore, having an advantage of comparatively lesser manufacturing cost, better quality and a higher efficiency WAAM became highly used technique for fabricating a component with a much higher metal deposition rate and least material wastage/least scrap. This paper provides a detailed overview of 3D printing of metallic object by inheriting WAAM technique as manufacturing method. At first, the review introduces metal wire and WAAM technique of 3D printing, followed by WAAM systems that are being used to manufacture 3D component, and analyzing which aims to study metal deposition rate and mechanical properties.

The advancement and development of new technologies requires teachers to introduce new teaching resources into the educational process of teaching Informatics and Computing. By introducing mBot in teaching in a creative and interesting way, students' motivation to develop and acquire digital and computer literacy has increased. The work shows mBot as a new, innovative tool that introduces students to the world of programming in a simple way. The results of the empirical research among the students of the seventh and eighth grade confirmed the premise of increasing motivation, as well as the development of the interest and curiosity of students in the field of information and computing. The students also showed great interest in participating in competitions and projects.

Kraken 4 is the unmanned undersea vehicle being developed by AUV IITKGP, a team of 20 undergraduate students at IIT Kharagpur. Kraken 4 is an advanced version of our previous AUV, Kraken 3. This report describes the design and development of an AUV for the STUDENT autonomous underwater vehicle event, organized by NIOT, Chennai. This document discusses the general design methodology, modelling and simulation of the proposed conceptual design. With numerous improvements, this design presents a more agile vehicle with increased capabilities over previous vehicles. New advancements include a stronger frame, an improved electrical system and momentous software changes which affords improved mission reliability. The proposed model has 6 degrees of freedom with allowances for a robust navigational payload.
