Mind/Though Controlled Robot Arms

The human mind is an excellent feature of God’s creation. Only with our mind, our body parts are controlled and made to do certain activities. Thus, when a person is brain dead, he cannot move his body or lift his arms and legs. The mind is the main thing needed to make the whole body function more effectively. Now, according to the new research study, the human mind can control robot arms. Robot arms are fitted to persons who have lost theirs in an accident or through some other means. For those who are disabled, just a mere robot arm which does actions only when a button is pressed doesn’t help. To make a more efficient and effective robot arm, scientists have created a robot arm that can be controlled by the person’s mind. The mind is used now though to control robot arms. The Rehabilitation Institute of Chicago introduced the first woman to be fitted with robot arms or bionic arm technology. This woman met with an accident, and her left arm was amputated from the shoulder. She has now been fixed with a robot arm with which she can now think and make the arm do the things…

Invisibility Technologies

Invisibility is often used in movies to express a magical feeling in the minds of the viewers. The word ‘invisible’ itself is magical and needs a lot of connotation. When something is invisible, it creates a magical effect and a questioning mind, and this makes the viewers probe into the field of invisibility technology. Really is there something called invisibility cloaking? Fictional movies have used invisibility cloaking to make something disappear for some time, and when the cloak is removed, the thing or the person appears again. In 2008, a physicist named Michio Kaku prophesied that a feasible invisibility device like the ones used in Star Trek could emerge from research laboratories. He also quoted David Smith of the Duke University who had used meta-material to bend light around an object. He also quoted that German scientists have found that a meta-material can make the red light around the object.

Fuel Cell Technology: Advantages and Disadvantages

In this age of technology, there is a development every minute in almost all the fields in one regard or the other. Such a significant result in a lot of alternate energy is the Fuel cell. A fuel cell, in simple terms, is an electrochemical energy generating device. It has been one of the most fascinating and interesting aspects of today’s world’s technology. Many things are yet to be developed in this field, and there are a huge scope and application for these Fuel Cells. These fuel cells are being under research by many people all around the world. Construction and Working There are many different types of fuel cells. But the basic construction and working of a fuel cell are the same, and the concept behind it is also the same. The Fuel cell works on the principle that energy is produced when some chemical reaction occurs. If this energy can be tapped, it can be converted into practical means. In a conventional fuel cell, the reaction occurs between hydrogen and oxygen, and water is formed. This is the primary chemical reaction that happens, and energy produced by this is tapped through proper channels and used for several applications.…

Automated Guided Vehicles

Automated Guided Vehicles help transport the raw materials, semi-finished products, and finished products within a workplace. Initially, in any industry or a workplace, the materials are transported from one work station to another work station manually or by using a vehicle that the human operates. Because of the manual interaction, the time taken for transporting the materials is high, and because of the increased time, the production rate of an industry comes down. To increase the production rate and utilize the resources like labor, machine efficiently in an industry, Automated Guided Vehicles have been brought into existence. The Automated Guided Vehicles cannot be installed in the workplace as such. It needs a lot of planning and design. This is because the Automated Guided Vehicles installation is costlier, and once installed, it would be difficult to change them. Thus, before installing the Automated Guided Vehicles, the Automated Guided Vehicles’ installation and movement region should be pre-determined. The layout of the company plays a vital role in the Automated Guided Vehicles system installation. Automated Guided Vehicles’ primary purpose is to reduce the travel time of the raw material or the workpiece. So the shortest route between the workstations has to be identified,…

Topobo – robot with kinetic memory

Robot toys are trendy among children these days. Especially DIY robot kits are getting more popular as these kits stimulate imagination and creativity. Topobo kit is becoming a most playful robot kit with kinetic memory where the assembled robot can memorize its motion and play it back. It is possible to teach robot various motions like animal walk, dance by simply guiding it. Three researchers of MIT Media Lab developed Topobo. This is not a new toy, but since 2003 it was used for various exhibits, and only a few lucky could try this toy. Now, this kit is widely accessible.
