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.
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
In the previous tutorial, a brief introduction of Internet of things was presented. The importance, challenges, applications and trends in IOT were discussed. Now, equipped with basic understanding of IOT, it’s time to investigate the building blocks of IOT. IOT is developed as a package with integration of various technologies. Each technology has its own principle role within the IOT system. In this tutorial, the basic building blocks of IOT and their place in an IOT infrastructure will be examined.
The twenty first century commenced with the rise in the use of internet. In year 2000, the internet comprised of 51 percent of information transfer in the telecommunications which soon surged to 97 percent in 2007. Though the internet began its humble journey interconnecting computers across the world and raise to dominate the telecommunication sector, the idea of internet is now bound to extend beyond computers and leap beyond telecommunications. From internet of computers, this century is going to be an era of Internet of Things (IoT).
Use of sensors is pretty common in industries and organizations. But, Internet of Things (IoT) has put the usage of sensors at a completely different level. Again, the entire concept of IoT exists and survived because of sensors. What role does sensors play in IoT? Simply answered, they are the medium through which various physical objects are connected through Internet. IoT platforms function and deliver various kinds of intelligence and data using a variety of sensors. The world has gone digital and “smarter” through the interconnection of things via Internet through sensors.
In the previous tutorial, a basic architecture of an IOT system was discussed. From the discussions in the previous tutorial, it must be clear that communication network is the backbone of any IOT system. It is only the (internet) network that enables IOT devices (boards) and cloud based services and applications to communicate with each other. Without internet network, IOT is nothing. Data communication on an internet network is not as straight forward. There are myriad of heterogeneous devices connected over internet and these plethora of unique devices need to communicate in a secure, reliable and routed fashion.
When Prateek Kumar was at Delhi College of Engineering (DCE), he experienced a road accident near campus — which turned out to be a vital turning point in his life. That experience in 2016 not only transformed the way he approached his life but it also gave him a purpose: to make a device that…
8.3) Voltage follower Voltage follower is a negative feedback op-amp amplifier circuit. It acts like emitter follower configuration of transistor based amplifiers. They provide unity gain to the applied input signals. Unity gain means the output voltage will be exactly equal in magnitude with the input voltage. Voltage follower In the above figure a non-inverting…
An amplifier is a circuit which can produce an output voltage, which is the product of input voltage with a value called voltage gain. An op-amp (operational amplifier) is a kind of amplifier circuit which can perform an operation (addition, subtraction etc.) on the input voltages, apart from simply amplifying the input. An op-amp (operational…
Andy Rubin, Nick Sears, Rich Miner, and Chris White founded Android Inc. in October 2003. Firstly, Andy Rubin developed Android OS for digital cameras but he realized that the market for digital camera operating systems perhaps was not all that big. In 2005, Android wasbought by Google and Andy Rubin along with other co-founders continued working under new owners. In 29 June 2007,iPhone was released by Apple Inc with iOS, which was the first OS in the mobile market.
The first law of thermodynamics states, “Energy can neither be created nor destroyed, but can be converted from one form to another”. The first part of this law tells us that there is a fixed amount of energy in the universe whereas, the second part gives a sneak peak into how we can utilize the available energy to alter it into a form which is useful to us. The ideal case would be that the entire portion of the source energy be converted to the form of our choice.
