Call it an effort of human mind or a miracle from human heart. But this is all happening with technology. We land in an era where everything that can be possibly thought, can also be practically put into. And that too quite reasonably..!! Just move the hand or walk your fingers over a thing and it works. Yes, it is the interactive gesture based technology I am talking about. A device which works on touchscreen technology is coined as Touchscreen. A touchscreen is an electronic visual display capable of ‘detecting’ and effectively ‘locating’ a touch over its display area. It is sensitive to the touch of a human finger, hand, pointed finger nail and passive objects like stylus. Users can simply move things on the screen, scroll them, make them bigger and many more.
Measuring an individual battery voltage or a whole bank of battery using any microcontroller(arduino, microship pic, Avr, Atmega, Intel, NXP, stm32)is an easy task. You can find many tutorials on internet on how to do so. But what about if we want to measure an individual battery connected to a cluster of batteries in series…
Proximity sensors — often called, proximity switches — detect the presence of nearby objects without making physical contact with them. These objects are called targets. There are several types of proximity sensors, including those used to detect metallic or non-metallic objects. Others are used to detect a specific object. These sensors also rely on different working…
Current feedback (CFB) operational amplifiers (op amps) and voltage feedback (VFB) op amps have almost as many similarities as differences. CFBs and VFBs both have inverting and non-inverting inputs, a signal output, inputs for positive and negative voltage supplies and use feedback and gain resistors to stabilize circuit operation and set circuit gain. That can…
Raspberry Pi was a revolutionary initiative. Nobody had ever thought that Single Board Computers (SBC) apart from their industrial use for embedded systems applications will come to a resort for educating young computer science professionals. The technological advancements removed the necessity of learning bizarre intricacies of the computer architecture and systems. But, soon it was realized that the lack of exposure to such integrated details will be a drawback for the new generation of computer professionals. And then it was the Raspberry Pi foundation that took the plunge. From the time of launch of Raspberry Pi 1 Model B released in 2012 onwards, by now Raspberry Pi 3 has already launched in February 2016.
Ever since robotics could reliably automate many human tasks, engineers have been diligently trying to add the five senses to these capabilities — as in sight, sound, taste, smell, and touch. The most significant so far is vision. However, how people see and how machines “see” is quite different. The human eye is a complex…
The fusion of technology with knowledge creates what the world once assumed as miracles and biotechnology can be considered as a perfect example where the knowledge of biology when blended with technology is making the world a better place by enhancing the quality of life and alleviating the human sufferings. ‘Biotechnology’, the term was coined by a Hungarian engineer, Karl Ereky and is defined as per the UN convention on biological diversity as, “Any technological application that uses biological system or living organisms to make or modify the process or products for specific use.” Biotechnology has touched almost every aspect of human life and has carved its niche too. Biotechnology dealing with medical and health care is termed as Red biotechnology. It is Green biotechnology, when it concerns about agricultural processes and White biotechnology when comes to industrial processes.
The Arduino L293D motor driver shield guide is a robobtics project that involves driving various types of motors. The most common types used for robotic applications include DC, servo, and stepper motors. However, these motors typically cannot be driven directly by Arduino or another microcontroller. This is because of their higher current and power ratings,…
As soon as we come across the word robot, we tend to imagine a metallic structure with arms and legs carrying a human-like appearance and running errands for our help. However, in actual terms, it’s just a machine operated externally or through a controller embedded within and doesn’t necessarily look like a human. Technically, robotics is a branch of Science and Engineering which deals with designing, constructing, and operating robots as well as computer systems for their control, sensory feedback, and information processing.Interestingly, the concept is almost as old as the hills with the first robot dating back to 350 BC, built in the form of a mechanical bird, by a Greek mathematician named Archytas. Although the term was coined ages ago, the actual potential of the fully autonomous robotics was realised in the second half of the 20th century.
As we discussed earlier about the amazing world of robotics, it’s believed that fully autonomous robots weren’t developed until the second half of the 20th Century. In all these years, a lot of new inventions have taken place from drones to nanobots; not to forget the animal robots and humanoids that look just like living beings. However, this is not it! There is a lot more than what has been explored till now. The future of robotics would be re-defined by soft robotics, a concept that is still unknown to the masses.
The Robots are mechanical devices equipped with software based intelligence that can perform specific physical tasks. There are many kinds of robots and robotic applications. The robots are designed to suit their application and their mechanical design, body, electronics, and software are designed accordingly.The robotic vehicles or robotic cars are one of the many types of robotic designs. The robotic cars are designed to move around plain surfaces where they can perform certain tasks either through remote controlling or autonomously. They are equipped with sensors, control circuitry and actuators for their operation.
Robots got their name from a Czech word “Robota” which means slave or any mechanical item that can help its master. Robots are mechanical devices that help to perform specific tasks for the humans. The term ‘Robot’ can be used for any mechanical device equipped with the software-based intelligence to perform specific physical tasks.The robotic cars or robotic vehicles are one of the many robotic designs which are developed to move around for performing physical tasks. The motion of such robot itself involves the application of power and use of motors. In making such a robot, there needs to be a balance between the load (weight of Robot), Battery and Motor used.
A team of researchers from the Cornel University recently developed flexible optical waveguides that permit the robots to get a feel of their surroundings by scaling external strain. The new innovation presents a strong alternative for the existing bulky and rigid tactile sensors that are embedded in regular robots. The solution was discovered in a soft prosthetic hand that is capable of demonstrating the final findings of this research team. An optical waveguide can be understood as a structure that directs visible light just like an optical fiber.
We know them as the most popular search engine in the World Wide Web. They are much more than that. They pioneer in inspiring innovation in the field of technology which is beyond their time. The google driverless car is a project by google which involves the development of technology to make a car self-dependent. The software that google use to automate cars is known as the “Google Chauffeur”. They do not produce a separate car but install the required equipment onto a regular car. The project is currently being led by google engineer Sebastian Thurin under the aegis of Google X.
What is USB? UNIVERSAL SERIAL BUS What does it do?It connects your laptop or PC to the peripheral devices attached to it.How does it communicate?You attach the device using a cable to PC and communication is initiated within a fraction of seconds. However, what looks easy on our end is a complicated process in the USB system. It may be single step in our stride to attach the device and start working but for the system it’s entirely a different picture. In that fraction of second after the device is attached, it initiates step by step process to make communication possible. It starts right from alerting the PC about the attachment, change in voltages at ports, then addressing the devices, gathering the information, loading the drivers and finally communication. Let’s understand each of these steps in detail to get a crystal clear picture about the working of USB.
In the near future if you are if you’re late for work and you don’t have time for breakfast your car will be there for your rescue. You will sit back, relax and enjoy your breakfast while your car safely drives you to your destination. No, this is not a sci-fi movie scene I’m talking about. This is soon going to be a reality!Google has been working on driverless cars since 2009. Automakers are currently working on new technology that will allow the cars to drive themselves. The technology uses a Chauffeur system called LIDAR (light detection and ranging). They’re also modifying the existing technologies such as self-parking and pre-safe systems to make the driving safe.
We had all imagined what the future would be like in our childhood, picturing pretty intense technology like flying cars, houses floating in the air, holographic telephones, etc. But we look at the world now and see those ideas actually come to life. One of such devices is Google’s latest project, “Google Glass”. What is Google Glass? What does it promise to do? What are its salient features? We will find out all this and more as we go further.In simple terms, google glass is a computer which you can wear on your head the same way as in you would wear a set of spectacles, which comes with an Optical Head Mounted Display (OHMD) working on a class of technology called “Augmented Reality”.
Life has existed for millions of years before electricity was ever developed. All thanks to the giant Nuclear Fusion reactor at the center of our solar system, ‘The Sun’. The Sun generates energy from its core where Hydrogen atoms fuse to create a Helium atom producing tremendous amounts of energy in the process. This energy is essential to life on earth. The sunlight is used by plants to produce food which is directly or indirectly the food source to all living things; it is responsible for seasons; its heat maintains water in its liquid form which is primary for life to exist; sunlight is an essential source of vitamin D to the human body and many more life supporting processes which are either directly or indirectly choreographed by the sun.
Flexible printed circuit boards are at the forefront of the new wave of electronics found in healthcare, military, and consumer markets.Researchers are continuing to push the limits of possibilities for flexible PCBs, expecting the industry to grow five-fold in the next 10 years.New materials, such as polyimide, allow a thinner, lighter product with the ability to move more freely.Conductive ink printing allows the elimination of connectors and cables, improving connectivity and assembly costs.The traditional process for manufacturing PCBs requires as many as 6 steps. New knowledge has shortened the process of manufacturing flexible PCBs to as little as 3 steps
