 Robotic technology can be found in clocks, remote control vehicles, automobile computers, Aibo, factory robotic arms, self-guided rovers, service bots like ASIMO, robotic toys like AIBO or Robo-Raptor and a CNC milling machine. To be considered a "robot," the specimen must be able to interact with its environment and physically do something. Most recently, robots are being used in surgery, disaster recovery and firefighting. Historically, ancient people believed in the existence of a humanoid robot species. The Greek god Hephaestus was thought to have created mechanical servants to help him build temples. Furthermore, the Jewish people thought that clay golems could come to life and the Norse believed that clay giants could awaken. In 4th Century BC, Greek mathematicians Archytas of Tarentum proposed that he could create a steam-powered bird known as "The Pigeon." Additionally, Hero of Alexandria (10-70 AD) devised automated machinery powered by air pressure and st...

 Knowledge about selling used equipment and machinery online The investment in machinery can be recovered by selling it as second-hand equipment. This market is huge, and many websites in different countries are dedicated to the trade of used equipment and machinery. Due to the development of the Internet and the improvement of logistics capabilities, cross-country trade is also possible. It depends on where the buyer finds second-hand equipment to his satisfaction. All kinds of second-hand equipment can be sold online and even auctioned. What kind of second-hand machinery and equipment are for sale? Various industrial machinery, such as packaging, printing and other industrial machinery and equipment, pumps, tools, industrial hardware, components, etc. The classification of second-hand machines and equipment can also be described as follows What are the sales channels for second-hand equipment? ·Unreserved auction-no reserve price ·Reserved auction-fixed reserve price ·Private sal...

The word robot comes from the Czech word "robota", meaning "forced labor." The stuff of science fiction robotics in the 21st century is different than your parents or your grandparents' ideas of robotics. What used to be thought of as futuristic improbability is now becoming a reality. There are, theoretically, three Laws of Robotics. The Laws of Robotics were developed by a small group of scientists who believe that robotics is the wave of the future. The first law, referred to as law zero, is that a robot may not injure humanity, or, though inaction, allow humanity to come to harm. The second law states that a robot may not injure a human being, or, through inaction, allow a human being to come to harm, unless this would violate a higher order law. This law was created so that mankind would seek not to create robots that would harm people. The third law is that a robot must obey orders given it by human beings, except where such orders would conflict with a hi...

Individuals with disabilities are often looked upon with frown or with pity because they're incapable of performing even the minutest tasks particularly when the disability is the reason of not getting arms or hands.Let's face it; our biceps and triceps and hands are what we use to do our everyday duties. We take a bath; do our writing, eating, work and almost everything with the use of our limbs and hands. So what occurs if these arms and hands were taken from us by mere accident? Surely we'll feel terrible and find ourselves depressed more than the fact. But now, technologies provides a solution. Science has made ways to say that getting disabilities isn't the end of existence.Many artificial arms have been invented to help individuals with disability. Some were even tested on monkeys. An additional one is really a prosthetic equip designed by Dean Kamen's known as "Luke" Robotic Equip which was a mere experiment and might arrive to an end because of lac...

In this article, I will explain the term "total harmonic distortion", often also called "THD" which is frequently used to describe the performance of wireless speakers. Looking for the perfect model from the huge amount of products, you may have a hard time understanding some of the technical language and terms that you will find in the specifications of today's wireless speakers. THD is usually not as easily understood as some other commonly used terms such as "signal-to-noise ratio" or "frequency response". THD is expressed either in percent or in decibel and shows how much the signal which the speaker outputs differes from the audio signal which is fed into the speaker. A -20 dB or 10% distortion means that one tenth of the radiated sound is a result of distortion while -40 dB or 1% would mean that one percent of the energy are harmonic products of the original signal. Harmonic distortion inside a wireless speaker is actually the result of...

A servo system is one that corrects system errors (position, speed, torque) by using a feedback device. Making a motor a servo motor is less related to its structure and operation, but more to whether it contains a feedback in a closed loop system. Therefore, what types of motors can be used in the servo system? This is not a question that can be answered simply. Because there are many ways to classify motors. And manufacturers usually use different terms to describe the same type of motor. This makes explaining the classification of motors a highly confusing effort. To help you solve this confusion, the following is a guide on motor terminology and a simple explanation about the common types of motors used in servo systems. There are three ways to classify motors-through current-DC or AC; through commutation-brushless or carbon brush; through the speed of the rotating magnetic field (rotor)-synchronous or non-synchronous. 　　 AC or DC 　　 The basic classification of a motor is whether i...

 What is the difference between servo and stepper motor? Servo and stepper motors have the same structure and use the same operating principle. Both motors include a permanent magnet rotor and a stator with wound windings. Both are operated by electricity or applying DC voltage to the stator windings, which means that the rotor moves. However, this is the only similarity between servo and stepper motor.  Stepping motor drive method 　　 Stepper motors have 50 to 100 poles and are two-phase devices. In contrast, servo motors have 4 to 12 poles and are three-phase devices. 　　 The stepper motor driver generates a sine wave with frequency that changes with the speed, but the magnitude is a constant value. 　　 Servo drives, on the other hand, generate sine waves with frequency conversion and magnitude, which allows them to control speed and torque. 　　Stepping motor control method 　　The traditional stepping motor advances to a certain number of pulses to move after receiving an instruc...

The chemical, pharmaceutical and food industries all face unique product quality challenges when dealing with foaming, scaling and solids. Using conventional distillation techniques, these processes can be very difficult and costly. The newly developed distillation equipment makes the work of all departments served by these distillation equipment easier. There are various effective and efficient distillation equipment on the market. Many manufacturing companies have produced a series of distillation kettles of various capacities that are widely used in various industries, such as chemical processing, food processing, etc. Depending on the application, these kettles can be equipped with coil coils, jackets, and tube bundles. The steam from the kettle passes upward through the coil into the shell, condenses and collects at the bottom, and is discharged as distilled water. The water from the heated cooling water supplements the water in the kettle, and it can be automatic if needed. Defin...

 For many companies, industrial machinery is absolutely necessary, and industrial machinery may cost tens of thousands of dollars or more. Purchasing machinery from an affordable and capable supplier or manufacturer usually means that the company can Resume competitiveness in the domestic market.
