Robot Record Volcano Eruption in Seabed
Yes, a robotic submarine named Jason had already witnessed the eruption of a volcano which is 4,000 feet below the water surface.
Mountain, located in the Pacific Ocean, precisely bordered by Fiji, Tonga, and Samoa, discovered by researchers in May last.
In a conference in San Francisco, high-definition video footage of volcanic activity is then displayed.
Scientists from NOAA and the National Science Foundation had never witnessed the eruption of a deep and detailed as this.
"We have not seen this before. And now for the first time, we saw lava flowing on the seabed," said Joseph Resing, mission chief scientist as well as staff of the chemical oceanographer at the University of Washington.
Mission to record the volcanic eruption in the sea using these robots requires a period of 25 years in the making. However, waiting for so long been paid off already.
From the records of results of the expedition "Western Eyes", the scientists hope the image, data, and samples obtained can shed light on how Earth's crust formed.
The research may also help explain how some sea creatures survive and thrive in extreme environments, and how the Earth behaves when tectonic plates collide.
With these findings, scientists are also expected to learn how to survive in the underwater environment. Meanwhile, the researchers could also see the creation of rare material - only happen in a million years - the so-called boninite.
Basic Robot Making
"Man can run, but our capabilities are not nothing compared to insects or other animals," said John Schmitt, a professor in the OSU School of Mechanical Engineering who led the cockroach robot project.
If the robot cockroaches runner style made this a success, Schmitt believes any point will vary. Robots will do the heavy duty operations such as for military, law enforcement, or space exploration.
Researchers at OSU trying to identify the mechanical and biological principles why certain animals can run very well and almost without effort. Through computer models, they created the concept of robot-like.
It is hoped one day, cockroach-inspired robot is going to materialize for hazardous areas visited. And because of his running so fast, they can get the hell out if it gets threats.
Line Follower Robot
There are several systems that are important in making a line follower robot is a robot Mechanical, Electronic and robot programming language. Associated with mechanical robots is how to choose the material physical robot builders. As for the electronic robot is a robot that includes a series of robot main controller (main controller), a series of sensors, and driver circuit. And the system is important in making line follower robot that is language programmer (software). Is the part that is used to program (fill) IC microkontroler. Programmable software which is often used is the Assembly Language, C / C, Bascom (compailler language).
There are two kinds of line follower robot line follower without using the program and the regular line follower with microkontroler program. Basically it works the same way that distinguishes between black and white surfaces. it's just that using the program microkontroler more complex and more perfect if the appeal is without a line follower using the program. In terms of cost is very clear that the line follower using the program microkontroller more expensive in the making.
The components that need to be in siapka to build a line follower is
Robot Body
To build a robot body we can use acrylic, that looks like glass. For the simplest pembutan we can use a CD, a few modifications will result in a pretty good body.
Akuator robot.
Akuator robots here we use a DC motor maknet permanent. Dc motor can be obtained from children's toys, or from a dc motor from a toy Tamia. To penyetabilan motion required a gearbox.
Wheel
We need 3 rear wheels is 2 wheels and one front wheel. For the rear wheel we associate with dc motors. For the front wheel to move freely at the time of inflection, using only one wheel. Wheels are in use Castrol / idle wheel. Untuh simplest materials we can use BB Rexona packaging.
Censorship
The sensor is like a robot eye. Only by the robot sensors can determine the direction of motion. There are various sensors used in making a line follower. To membgaun simple line follower we use infrared sensors because pembuatanya very simple.
Electronics Line Follower
Electronics for a robot is as organs of support work for other systems. Additional electronic components: resistors, capacitor, condenser, Diodes (LEDs), transistors, switches.

Historical development of robot technology
Then the definition what is a robot itself? According to the site inventors.about.com robot is an automated device that performs functions normally ascribed to humans or a human-shaped machine. Perhaps a definition is less precise because there are some robots that are shaped like a human being or a part of human organs and replace the jobs previously done by humans even though many of its goals the creation of the robot is to it. Due to the fact that robots have successfully created and later became famous, it's not a robot that resembles the shape of human body organ or part. For example the robot dog Aibo ERS-210 made by SONY company.
Starting from a short story
Since when is a human robot knows? The legend says that first popularized the term robot in a short story (short story) entitled Runaround, written by Isaac Asimov in 1942. Actually the term robot already used by Karel Capek, a playwright from Czechoslovakia. Short story tells about the robot therapy. Inspired on the short story Runaround, Joseph Weizenbaum, a professor at the Institute of Massachusetts, making Eliza program in 1966. There are about 240 lines of code created by Weizenbaum to simulate a psikotherapy.
It was not only Prof. Weizenbaum are obsessed with the work of Asimov's short story Runaround it. Ten years before Prof. Weizenbaum makes the program Elilza, George Devol and Joseph Engelberger had already been talking about making a robot based on the idea that the story of the short story Runaround. They both then set up a company called Unimation, an abbreviation of the term Universal Automation. Unimation became the first company in the world to produce commercial robots. Even until now the company is reportedly still in production.
Period Robot Technology
Although there are some who may not be defined as a robot, but the results are arranged in order of creation or period below is considered as a development from the embryo of robot technology.
1. Sebelem year 270 BC, Ctesibus, in ancient Greece has made organs and water clocks that can make certain movements.
2. In 1818, Mary Shelley wrote the novel "Frankenstein" the famous and forbidding it. The story of the man who was created by Dr. Frankenstein.
3. 1921, the term "robot" was first used in a play called "RUR" or "Rossum's Universal Robots" written by authors from the Czech Republic, Karel Capek. Simply put this drama about human mengkisahkan making robots and robots that eventually kill the human who created it.
4. 1941, science fiction writer Isaac Asimov first used the word "robot" to describe the technology of robots and predicted the emergence of strong industrial robots.
5. In 1942, Asimov wrote "Runaround", a story about robots and introducing "Three Laws of Robotics".
6. In 1948, Cybernetics ", an article about the influence on the results of artificial intelligence which was published by Norbert Wiener. In those days, was also a pioneer of robotic technology in the UK, William Grey Walter created a simple robot, named Elmer and Elsie that mimic lifelike behavior using electronics.
7. George Devol and Joseph Engleberger create a robot arm that is programmed for the first time and created the term Universal Automation for the first time also.
8. In 1956, George Devol and Joseph Engelberger formed the company producing the world's first robot. In this year also an electronic robot squirrel-shaped and named Squee created.
9. In 1959, Computer Assisted Manufacturingg Servomechanisms was demonstrated in the laboratory at MIT.
10. In 1961, the first industrial robot was exhibited at the General Motors automobile factory in New Jersey. The robot was called UNIMATE.
11. In 1963, artificial robotic arm controlled by computer were first designed. Arm (hand) robot is designed as a tool for the disabled with the completeness of the six joints that provide the flexibility of the human arm.
12. In 1965, the first manufacture of advanced systems and called DENDRAL. This program is designed to carry out the accumulated knowledge of the subject experts.
13. In 1968, Marvin Minsky made arm Octopus tentacles called.
14. In 1969, the manufacture of the Stanford arm which is driven by electricity. This robotic arm controlled by computer.
15. In 1970, the emergence of Shakey the robot is touted as the first mobile robot controlled by artificial intelligence. This robot was created by SRI International.
16. In 1974, the design of a robotic arm that works based on feedback and pressure sensors. The robot, called by the name of the Silver Arm is used for assembling the components in the field of industry.
17. In 1979, the first time demonstrated the ability of a robot passing by in a room full of chairs. Stanford robot dubbed it can avoid crashing into the chairs are placed randomly in the room. This robot is equipped with cameras that convey images to the computer field laluan. Furthermore, the computer account object distance and the barriers that exist in the field.
In the period following the creation of robots can be obtained through a lot of information published by mass media. Please you are seeking information through electronic media or print media.
robot asimo(honda corp)
Honda Motor Company developed ASIMO, which stands for Advanced Step in Innovative Mobility, and is the most advanced humanoid robot in the world. According to the ASIMO Web site, ASIMO is the world's first humanoid robot that can walk independently and climb stairs.
In addition to ASIMO the ability to walk as we did, it also can understand body language and speaking programmed commands, recognize faces and voices and interface with IC Communication cards. ASIMO has arms and hands so they can do things like turn on lights, open doors, carry objects and push carts.
Rather than building a robot that will be another toy, Honda wanted to create a robot that would be a helper for people - a robot to help around the house, helping the elderly, or helping someone in a wheelchair or bed. ASIMO is 4 feet 3 inches (1.3 meters) tall, the height of the right to see eye to eye with someone seated in a chair. This allows ASIMO to do the job it was created to do without too big and threatening. Often referred to as looking like "a child wearing a spacesuit," ASIMO's friendly appearance and nonthreatening size work well for the purposes Honda had in mind when creating it.
Unless you know a lot about robots, you may not fully understand the incredible milestone it is that ASIMO to walk as we lakukan.Bagian most important of ASIMO's walk is the ability to change. Instead of having to stop and shift, and random stops, and stopped and shifted into a new direction, ASIMO bent and smoothly changed just like humans. ASIMO can also adjust the steps in case it tripped, pushed, or come across something that changes the normal flow.
To achieve this, ASIMO's engineers must find ways to work with the inertial forces created when walking. For example, Earth's gravity creates a force, as well as the speed when you walk. Those two forces are called "total inertia force." There is also the force generated when you connect your feet to the ground, called the "ground reaction force." These forces have to balance out, and the posture of the body must work to make it happen. This is called "time zero point" (ZMP).
To control ASIMO's posture, engineers worked in three areas of control:
Floor reaction control means that the soles of the feet absorb floor is not flat retaining the position of the company.
Target ZMP control means that when ASIMO can not stand up straight and the body begins to fall forward, it maintains the position by moving the upper body in the opposite direction with the arrival of autumn. At the same time, it speeds up a running quickly offset the fall.
Kicking foot planting location control when the target ZMP control has been activated. It adjusts the length step to regain the true relationship between body position and velocity and step length.
ASIMO's capabilities and Pengedalian
ASIMO robot is not autonomous. Unable to enter the room and make your own decisions about how to navigate. ASIMO either has to be programmed to perform certain jobs in certain areas that have a marker that he understands, or must be manually controlled by a human.
ASIMO can be controlled by four methods:
PC
Wireless controller (sort of like a joystick)
Gestures
Voice commands
Using 802.11 wireless technology and laptop or desktop computer, you can control ASIMO as well as see what ASIMO sees through the eyes of the camera. ASIMO can also use the PC connection to access the Internet and retrieve information for you, such as weather and news.
Wireless joystick controller operates ASIMO's movement in the same way you would operate the remote control car. You can make ASIMO forward, backward, sideways, diagonally, in circles, running in a corner or walk in lingkaran.Membuat ASIMO move by remote control may not seem that advanced, but ASIMO does have the ability to adjust step. If you have walked to the front, and he met with a slope or a kind of obstacle, ASIMO will automatically adjust the measures to accommodate the plains.
ASIMO can recognize and react to some of the movements and posture, allowing the user to Asimo nonverbal commands. You can indicate a specific place you want to ASIMO to walk towards, for example, and will follow your lead Anda.Jika wave to ASIMO, he will respond with its own wave. It can even recognize when you want to shake his hand.
and the need to move, and then control that moves. Servos use a position-sensing device (also called a digital decoder) to ensure that the motor shaft is in the right position. They usually use power proportional to the mechanical loads they carry. A lightly loaded servo, for example, do not use much energy.
ASIMO has 34 servo motors that move the body in the body, arms, hands, legs, feet, ankles and other moving parts. ASIMO manage a series of servo motors to control each type of movement.
ASIMO is powered by a rechargeable, 51.8 volt lithium ion (Li-Ion) battery that lasts for one hour on a single charge. ASIMO is stored in the battery pack and weighs about 13 pounds. ASIMO's battery takes three hours to fully charge, so the second (and third) battery is very important when you need ASIMO to operate for a long time. Users can charge the battery onboard ASIMO through a power or remove the backpack to be filled separately.
ASIMO, Robot from Honda Japan
One reason for Honda's ASIMO robot created in a few years ago was to develop a robot that can run itself, which is biased to help humans as well as their use in community practice. ASIMO robot research and development began in 1996 with a prototype robot P2, and in 1997 in the format of P3 robot.
Including the prototype of the robot Asimo P3, which can run smoothly and without noise. With ASIMO's height is about 120 cm visible eyes will align with the eyes of adults when adults sit in a chair. ASIMO is lighter than the P3, the higher 40 cm and 87 kg heavier than the Asimo. With a weight of 43 kg, Asimo can operate household appliances, grabbed the door knob, dance, and perform household tasks.
Advanced Walking Robot ASIMO has Technology that can predict and control the movement in the direction of gravity, which combined with the existing control run, ie, technology iWalk (intelligent real-time flexible walking). The combination of both technologies can produce a subtle change in direction, so it looks natural and stable like a human. Operation of the robot using the Simple Operation To, to facilitate the course of robots, flexible walking control, and operation buttons (from the motion cues and hand waving) which can be operated from a workstation or portable control mounted on the hand. The expansion of distance movement Asimo can be done by adding the angle of movement shoulder high around 20 degrees and elbow about 15 degrees horizontal, vertical arm motion also angle of 105 degrees, which is much broader than P3 robot.
