Smart Dust

Smartdust is a system of many tiny microelectromechanical systems (MEMS) such as sensors, robots, or other devices, that can detect, for example, light, temperature, vibration, magnetism, or chemicals. They are usually operated on a computer network wirelessly and are distributed over some area to perform tasks, usually sensing through radio-frequency identification. Without an antenna of much greater size the range of tiny smart dust communication devices is measured in a few millimeters and they may be vulnerable to electromagnetic disablement and destruction by microwave exposure.

Nicknamed “Powder” or “Dust”, the surface area of the new chips is a quarter of the original 0.3 x 0.3 mm, 60µm-thick chip developed by Hitachi in 2003. And this RFID chip is only one-eighth the width of the previous model.

Hitachi expects this tiny size will open the way to new applications for wireless RFID chips. The RFID “powder” can be incorporated into thin paper, such as currency, creating so-called “bugged” money.

The RFID Loc8tor can identify special RFID tags from a distance of up to 183 meters (600 feet), and the RFID chips have GPS capabilities.

“By taking advantage of the merits of compactness, high authenticity and wireless communication, and combining it with Internet technology, the µ-Chip may be utilized in a broad range of applications such as security, transportation, amusement, traceability and logistics.”

Humanoid robot

A humanoid robot is a robot with its body shape built to resemble that of the human body. A humanoid design might be for functional purposes, such as interacting with human tools and environments, for experimental purposes, such as the study of bipedal locomotion, or for other purposes. In general, humanoid robots have a torso, a head, two arms, and two legs, though some forms of humanoid robots may model only part of the body, for example, from the waist up. Some humanoid robots may also have heads designed to replicate human facial features such as eyes and mouths. Androids are humanoid robots built to aesthetically resemble humans

Humanoid robots are used as a research tool in several scientific area.

Researchers need to understand the human body structure and behavior (bio mechanics) to build and study humanoid robots. On the other side, the attempt to the simulation of the human body leads to a better understanding of it.

Human cognition is a field of study which is focused on how humans learn from sensory information in order to acquire perceptual and motor skills. This knowledge is used to develop computational models of human behavior and it has been improving over time.

It has been suggested that very advanced robotics will facilitate the enhancement of ordinary humans. See transhumanism.

Although the initial aim of humanoid research was to build better orthosis and prosthesis for human beings, knowledge has been transferred between both disciplines. A few examples are: powered leg prosthesis for neuromuscularly impaired, ankle-foot orthosis, biological realistic leg prosthesis and forearm prosthesis.

Besides the research, humanoid robots are being developed to perform human tasks like personal assistance, where they should be able to assist the sick and elderly, and dirty or dangerous jobs. Regular jobs like being a receptionist or a worker of an automotive manufacturing line are also suitable for humanoids. In essence, since they can use tools and operate equipment and vehicles designed for the human form, humanoids could theoretically perform any task a human being can, so long as they have the proper software. However, the complexity of doing so is deceptively great.

They are becoming increasingly popular for providing entertainment too. For example, Ursula, a female robot, sings, play music, dances, and speaks to her audiences at Universal Studios. Several Disney attractions employ the use of animatrons, robots that look, move, and speak much like human beings, in some of their theme park shows. These animatrons look so realistic that it can be hard to decipher from a distance whether or not they are actually human. Although they have a realistic look, they have no cognition or physical autonomy. Various humanoid robots and their possible applications in daily life are featured in an independent documentary film called Plug & Pray, which was released in 2010.

Humanoid robots, especially with artificial intelligence algorithms, could be useful for future dangerous and/or distant space exploration missions, without having the need to turn back around again and return to Earth once the mission is completed.

RoboBee

RoboBee is a tiny robot capable of tethered flight, developed by a research robotics team at Harvard University. The culmination of twelve years of research, RoboBee solved two key technical challenges of micro-robotics. Engineers invented a process inspired by pop-up books that allowed them to build on a sub-millimeter scale precisely and efficiently. To achieve flight, they created artificial muscles capable of beating the wings 120 times per second.

The goal of the RoboBee project is to make a fully autonomous swarm of flying robots for applications such as search and rescue and artificial pollination. To make this feasible, researchers need to figure out how to get power supply and decision making functions, which are currently handled via a tiny tether to the robot, on board.

The 3-centimeter (1.2 in) wingspan of RoboBee makes it the smallest man-made device modeled on an insect to achieve flight.

Design challenges

According to the RoboBee researchers, previous efforts to miniaturize robots were of little help to them because RoboBee's small size changes the nature of the forces at play. Engineers had to figure out how to build without rotary motors, gears, and nuts and bolts, which are not viable on such a small scale. In 2011, they developed a technique where they cut designs from flat sheets, layered them up, and folded the creation into shape. Glue was used to hold the folded parts together, analogous to origami. The technique replaced earlier ones that were slower and less precise and used less durable materials. The manufacturing process, inspired by pop-up books, enables the rapid production of prototype RoboBee units.

At micro scale, a small amount of turbulence can have a dramatic impact on flight. To overcome it, researchers had to make RoboBee react very rapidly. For the wings, they built "artificial muscles" using a piezoelectric actuator - a thin ceramic strip that contracts when electric current is run across it. Thin plastic hinges serve as joints that allow rotational motions in the wings.The design allows the robots to generate power output comparable with an insect of equal size. Each wing can be controlled separately in real time.

The ultimate goal of the project is to make colonies of fully autonomous and wireless RoboBees. As of 2013, two problems remain unsolved. First, the robot is too small for even the smallest encapsulated microchips, meaning there is no way for the robots to make decisions. Currently, the RoboBee has onboard vision sensors, but the data requires transmission to a tethered "brain subsystem" for interpretation. Work continues on specialized hardware accelerators in an aim to solve the problem.

Second, the researchers have not figured out how to get a viable power supply on board. "The power question also proves to be something of a catch-22", remarked Wood. "A large power unit stores more energy but demands a larger propulsion system to handle the increased weight, which in turn requires an even bigger power source." Instead the robots have to be tethered with tiny cords that supply power and directions.

Bermuda Triangle

Bermuda Triangle

The Bermuda Triangle, 

Bermuda Triangle has always been a mystery to solve. Many flights and ships have disappeared in the Bermuda Triangle, many scientists had stated many theories related to the Evil Triangle and its mysterious powers. But none of the theories have solved the mystery of Bermuda Triangle.

Bermuda Triangle was known as the EVIL TRIANGLE because peoples believed that the triangle has some paranormal power, missing of ships and aircraft is due to the giant beast that lives in that region, this was said in the past. And now in the present, people says that “the mystery of the Bermuda Triangle is because of the ALIENS”.

Whatever it may be, as a human I need some logical reason behind the mystery of Bermuda Triangle. And now after going through all the theories and assumption made by the popular people, I am here to say some of the things that gave me a solid reason for the mystery of Bermuda Triangle.

There are too many and I have put them all together into a single one

At First, there is a lot of Electromagnetic pulses* in that particular region that could destroy the electronic devices, Electromagnetic pulses * can dry out batteries and can cause a worse effect on ships and planes that could lead to the distraction, any mode of communication cannot be effective during the attack of the EMP*.

Secondly, Bermuda Triangle have many underground volcano that erupt Methane bubbles in a huge amount that causes disturbance of surface level of the sea water. Disturbance of surface level of the sea water causes surface tension that may lead to the collapse of the Tidal Waves. And this tidal waves can have a maximum height depending on the speed of the Methane gas and oil released by the volcano. This huge Tidal Waves can take down the ships.
