  3. Now a VCR remote can be programmed to operate several brands of televisions.This has been possible because of the revolutionary invention of Universal Remote. Universal Remote was developed in 1987 by CL9, a startup founded by Steve Wozniak, the inventor of the Apple I and Apple II. Universal Remote can be used to control numerous brands of several types of electronic devices for consumers. There are two types of Universal Remote- Low end and High end depending on the number of devices they can control. The features of Universal Remote are as follows: A power button and switch to select the electronic device to control; Channel and Volume Up and Down buttons; Numeric Keypad for channel numbers; Set button; D-pads for DVD navigation and set-up boxes. Higher end Universal Remote include Macro programming, LCD to display information, programmable soft keys, repeaters so that they are compatible with different designs available. Recently launched Logitech Harmony Ultimate is the Universal Remote aimed to control 15 devices with RF Control, Wi-Fi, Bluetooth, IR, Web programmable through Windows and Macs, rechargeable, works also through app-based platforms.
  5. The statement quoted above seems to indicate that the motor is running all the time. But later, you say So, does the conveyor motor run all the time, or only when a load is placed on the conveyor?
  6. Dear Ms. Chakraborty, Your posts so often seem like sales advertising. They describe new products, mostly in terms of benefits to the user, but tell us little of engineering interest about the product. Are you principally interested in selling thing? It seems to me that an appropriate post on this item would describe what engineering design innovations enable it to function. How do they package this capability in a suitable compact form? Please let us look more at engineering and less a promotional features. DrD

  11. Yes, that basically comes under home automation. Innovative devices for automation inside the home.
  12. Thank you, John and Sorry Sir. I was not aware in depth about the selenium package. Shared this article as I was going through the current technological developemnets.I would further gain knowledge about the same and write on this topic in upcoming days.
  13. Thank you, John. I had never heard of that. Why does this answer have to come from John, rather than our leader, Shalini? DrD
  14. What about automating basic daily tasks? Like turning off and on a home's bulbs based off the intensity of natural light.
  15. Selenium is a software package which can be used to test websites/ automate tasks to websites. For example, if I wanted to login every day to the mechanical-engg.com website and post a greeting e.g. hi, I would use selenium to perform this task for me.
  16. Automatic Conveyor is used to controlling the conveyor automatically by sensing the objects placed on the conveyor. Using RPM sensor, we can control the speed of the motor. The number of tags handled by the conveyor is displayed simultaneously on the speed of the conveyor. The Conveyor system saves the power of motor operating the conveyor by regulating conveyor automation. It consists of two object sensors, rpm sensor, rpm control circuit controlling the speed of the circuit. The object sensors detect the objects sends the signal to the motor driving circuit to on/off the motor. The Automatic Conveyor system thus saves the power of motor operating the conveyor by regulating the conveyor automation: the conveyor actuates only when the tag is sensed.

  18. Biosensors are analytical devices that convert the biological response into an electrical signal. Scientists have developed biosensors that can quickly detect dengue and could help create a cheap tool to diagnose the painful mosquito-borne virus that infects millions each year. They are looking to produce a testing kit that could cost around 30 dollars and take about 15 minutes to analyse blood sample for a key dengue protein.
  19. Hard automation tends to be heavy on mechanical engineering. I am thinking, for example, of cam controlled automated systems. I have seen a number of examples of this sort of automation, including (1) a pick-and-place robot that puts finished CDs in plastic cases, (2) a yogurt cup filling machine, where cams control the lowering of the dispenser nozzle, starting and stopping the material flow, and retraction of the nozzle, and (3) a paper cup making machine where all operations were cam driven to cut out blanks for a paper cup, roll the blank into the form of a cup, seal the edge, place a bottom in the cup and crimp the edge, and finally roll the top edge. In each of these cases, there were vast quantities of product to be produced in identical form. Soft automation, with electronic controls that enable different forms for the basic product lend themselves to things like automobile production where there are many variations on the basic car. Some cars will have one feature while the next on the order lacks that feature. Automated assembly must be able to adjust and compensate on the fly for these variations. While the assembly operation itself may remain largely a mechanical problem, the control tends to be more electronic using computer logic to adjust to each order. The word MECHATRONICS is a relatively new term, one that usually denotes systems that involve a high degree of electronic logic with a few mechanical components. This brings to mind things like tape recorders, CD players/recorders, cameras, phones, and similar products. I'd be interested to hear from other readers just what word do you use for electromechanical devices such as electric motors, generators, electric brakes, solenoid actuators, gear motors, etc? Does this fall under mechatronics in your thinking, or is there another term you think is more descriptive? DrD
  20. As this section deals with concepts/ideas and projects on AUTOMATION/MECHATRONICS/ROBOTICS, it would be highly beneficial if the group members discuss the technological upcoming in this field, projects they have worked upon involving this field or new concepts or ideas of their own. Please feel free to discuss on topics and feel free to comment. Let us discuss topics every day and each day will be knowledgeable and beneficial for all of us.
  21. How do you see shipping tools as something unique to automated systems? Can't tools be shipped in non-automated systems as well? I seem to be missing something here. DrD
  22. Material handling primarily involves movement, storage, control and protection of materials, goods, and products throughout the process of manufacturing, distribution, consumption and disposal. Basically, for the industrial domain, automated material handling equipment are used. Different types of handling equipment include positioning, storage, unit load formation and transport. Transport equipment includes cranes, conveyors, industrial trucks, positioning equipment include lift table, hoists, balance, industrial robots, storage includes the AS/RS systems and unit load formation equipment include pallets, skids, slip sheets, tote pans, bin, bags, crates. Benefits of automated material handling systems include labour cost reduction, time reduction, production quality and quantity improvement and the possibility of shipping of tools.
  23. Yes, Sir, that's the inbuilt nature of automation. Though the machines are expensive, the production quality and quantity are large. Also, irrespective of the complexity of the process, the precision, accuracy, and flexibility are quite good.
  24. One of the most interesting examples of automation that I have worked on is a paper cup making machine. Everyone has seen paper cups. They come in many different forms, from simply conical forms to more complex truncated cones with a flat bottom. The come in small, medium, and very large sizes. How do you make such things cheaply, cleanly, and fast? Starting with a long coiled sheet of paper, the pattern must be cut out, rolled up, a bottom added, and the whole thing sealed. This is quite a sequence of operations, and the machines that do this consist of a number of stations, each station performing one operation and then passing the work piece on to the next station. The machines that I worked on were all cam controlled, which is to say they were a form of hard automation. Cam driven systems are extremely repeatable, but they are fairly difficult modify for a different product. They are also capable of operating at incredible speeds. I saw machines making 1200 paper cups per minute. The literally come flying out the end to be caught and packaged for distribution. The machines are quite expensive, but the number of paper cups they can make is absolutely huge! DrD
  25. Let's begin in the chronological way of knowing what actually is Automation, types, implementation and so forth. In this article, we can easily generalize the types of Automation systems. While discussing on the brief overview on Automation, we can realize that its the mechanization which has provided an edge to automation, however, there is an immense need of maintenance and feedback while dealing with them. The integration of several industrial places all across the world shows a clear indication on how we have stepped into a new era where we are seamlessly enhanced productivity and made our task easier. Hence, let's take a note of the different types of Automation. Basically, they are of three types: fixed automation(hard automation), programmable automation (soft automation), flexible automation. In fixed automation, we use special purpose equipment, the operation is simple but it's hard to incorporate changes in the design. In programmable automation, the production equipment is designed with the capability to change the sequence of operations to accommodate different configurations. Flexible is further an enhanced programmable automation system where there is no production time lost and changeovers can be made easily. It can be also categorized into the following: Industrial Automation performs tasks with minimal human intervention and repetitiveness. Numerically Controlled Machines perform operations with the help of computers with high accuracy and minimal errors. Industrial Robots are the most important segment of automation as they have helped in maintaining the persistence of industrial activities. Flexible Manufacturing Sytems have also enhanced the flexibility in manufacturing with changing parts and processes. Computer Aided Manufacturing involves usage of computers in production, planning, and control of FMS systems, generally CAD, CADD. Hence, automation has not only helped in fetching the big manufacturing targets in an easier way but has also increased the efficiency with which the systems work currently.
