Korean scientists have created the robots that are small enough to explore the human body and driven by the heart muscle.
Sukho Park at Chonnam National University, Korea, and colleagues have designed a micro-robots driven by the cell. Park team to make the robot with the heart muscle to grow the network from a mouse on the small-frame robots are made from polidimetilsiloksana (PDMS). PDMS is a polymer biokompatibel make robots that are suitable in pengaplikasian biomedik.
A special on robots this, Park said, is they do not require an external energy supply. But the cells of the heart muscle berelaksasi and berkontraksi that provide energy. Muscle cells get the energy own heart from a glucose culture medium. Cells that beat themselves, allowing the robot moves six feet.
This robot has three short front legs (400 micrometer long) and three feet behind the longer (1200 micrometer long), all mounted on a body segiempat. At the heart cells berkontraksi, feet behind the long bend into. This difference in friction between the front foot and back foot, pressing the robot move forward. The researchers measure the average speed of robots is about 100 micrometer per second.
Park said that robots like this crab can be used in the body cavity to clean up or clog the vessel, with a release agent solvent to clean the stoppage of them .

Grassroots Robotics
With financial support from the Indiana Department of Workforce Development (IDWD)—a state agency—IRE is able to provide free workshops and competitions that benefit teachers, students and schools. At the end of the three-day teacher workshops, the teachers get free software, curriculum guides and a VEX Starter Kit each to take back for use in their classrooms. 
As part of the deal, teachers must field one or more student teams to compete in robot competitions held locally in the state. This has been a boon for the teachers because the students are extremely enthusiastic and highly motivated, and the resources for the new robotics programs are almost entirely paid for by the state, i.e., by taxpayer dollars. The IRE program costs teachers only two or three days of their time at a training workshop; the teachers and their school boards are not asked to pay for anything.
Backing for the IRE’s robotics programs has come from the IDWD because that agency is charged with ensuring a flow of technically trained graduates into the local workforce. IDWD partners in this program with Ivy Tech Community College of Indiana—a statewide college system that provides the facilities for the teacher workshops and that ultimately trains technical majors for Indiana industry.
Dan: I was on a visit to the Indiana Statehouse to give a robotics demonstration to our legislature. I was there with my brother, Luke, who works with me on grant projects. We were trying to convince the state legislature that it was a good idea to fund educational robotics. To set the context, the Indiana Workforce Development agency has been a big supporter of FIRST in our state. We were there with our FIRST machines, probably 10 teams. We were offering quite a show, making a lot of noise; a lot of robots were moving around.
The people from Workforce Development had heard we were coming and stopped by and asked what was the biggest hurdle in getting more schools involved with robotics programs like FIRST. I said, “training.” That’s the first hurdle; the second is money. They asked, “What is the best way to solve this?” And I told them “Let us train them. We will use your funding and give the teachers the equipment they need so that they won’t have to get it from their school.”
They then asked how much it would cost; now, I was on the spot. I turned to my brother and we whispered back and forth and then I turned around and said that it would cost in the vicinity of X dollars. Based on that, they figured that their cost per teacher would only be around $300 for three days of training and all of this equipment. They had never seen anything like it and asked me to commit this to writing in a proposal. This was on a Tuesday, and I said I could have it to them by Friday, so I spent a couple of sleepless nights putting the proposal together. What happened next?
Dan: The following week was business as usual until Wednesday, when we jumped in the car to drive to Atlanta for that year’s FIRST national competition. While we were there, my cell phone rang; it was our school business office manager at Ivy Tech, who said that a check had shown up with my name on it and that it was for a substantial sum of money, and nobody knew what it was for. The DWD thought the proposal was such a good idea they jumped on it in less than a week! When that later played out, we actually surpassed our first year’s projected numbers; we came in under budget.
Dan: All have been given free VEX Starters, current Autodesk Inventor software, a DVD with a curriculum that we have developed over the years and robot project and competition notes. This is provided in Microsoft Word format so that they can edit it. They also build a robot during the workshop and compete with it on the third day . Read More..

class="style1">Everybody Wins
This expanding program is a win-win for all. It has long been recognized that robots are a learning accelerant—a catalyst that galvanizes students’ interest in STEM subjects (science, technology, engineering and math). Because robots are entertaining and fun to build, operate and compete with, students progress more quickly in their studies and become more aware of technical career opportunities along the way. From the viewpoint of engineers, educators and government, this is of critical importance in a changing world in which our technological leadership is being challenged.
Teachers progress in their professional development and the performance of their schools is recognizably enhanced. The Ivy Tech campuses where the workshops are held benefit through a strengthened working relationship with the teachers who are educating the students who will soon be going to college. Even hobbyists in general benefit because the program heightens the demand for robotics technologies that squarely overlap with those enjoyed by hobbyists of all ages; in other words, the robotics market itself is expanding as a result of the IRE initiatives.
The Leaders behind the IRE
Dan Ward is the Design Technology Program chairman at Ivy Tech, the only community college system in Indiana. Dan and his brother, Luke, an assistant professor at Ivy Tech, have been pioneering IRE robotics educational programs since 2000 with the goal of inspiring high school students to pursue technical careers. Kyle Wiley, assistant professor at Ivy Tech, joined their team, and what they have achieved in two short years is nothing short of phenomenal. Their accomplishments could serve as a role model to change the landscape in technical education nationwide to our country’s benefit. In fact, Dan and his IRE associates have been contacted by educators in several states who wish to replicate the successes spearheaded there in Indiana.
When did you first launch a robotics program in Indiana, and how did that come about?Dan: I was on a visit to the Indiana Statehouse to give a robotics demonstration to our legislature. I was there with my brother, Luke, who works with me on grant projects. We were trying to convince the state legislature that it was a good idea to fund educational robotics.

class="response_title">Robot:When and where are the workshops held?
Dan: Teacher workshops are held in the summer, June through August, on Ivy Tech campuses around the state. We have a 10-week window to hold eight workshops.
Robot: Can you characterize the process of writing a grant? What do you put into it?
Dan: Those in a position to allocate money want to see sustainability; that’s first. The grant writer must say that with the history here, there is this much more we can do, and that it will be self-perpetuating—that we have people who are involved and that they are going to stay involved. That’s the important part. Even if you don’t have it at the moment, you have to prove that it will be sustainable in the end.
Robot: How many have you trained, and when did your workshops begin?
Dan: The first year, we trained 35. That was a proof of concept on an old grant. We did that on donations; I put a little money into it. We scraped and got the information together. We had really good luck. The teachers really seemed to enjoy it.
The next time around, summer of 2006—and that is the same time as we partnered with the Workforce Development people—we had 121 participants. That was without advertising—just word of mouth. We had requirements defining what we could use the money for. We were able to get 121 people representing 102 high schools.
In 2007, we did a little marketing and sent out some emails. The Department of Education had a mailing list, and the science technology teachers received this on their list serve as well. I think word of mouth did more for us than any other channel, quite honestly. At this point, we have trained 560 teachers—560 robots have been delivered into teachers’ hands.
Dan: All have been given free VEX Starters, current Autodesk Inventor software, a DVD with a curriculum that we have developed over the years and robot project and competition notes.

ISLAM IS BEAUTYFUL
Did you feel in life is how beautiful Islam? If not, how I felt that a Muslim living under the auspices of religious past. All the guide of life in the Al-Quran. This is the real source of happiness creator of the universe and all its contents, including humans.
Unfortunately, many people still dig various science is not useful in the search for happiness. Human search for diamonds in the earth in the light of diamonds are in the room. Human resources do not find happiness from the place.
Islam as a peaceful means, then peace will be achieved in the embrace of Islam wholeheartedly. They never felt that in the shade enjoying the world of Islam because Islam consider the eye. Syumuliatul Islam is not felt in himself.
For example, the beauty of Islam can be felt in peribadahan. How beautiful harmony with human nature in the context of Him. Sun has been working for years to Launch Almighty Creator, with rises in the east and sinking in the West. Sun still accompany every thing every day. He was never absent. Loyalty being named the sun rise this gratitude will feel themselves in favor of worship Him.
When bow down in prayer feels once syahdunya umbrella in the beauty of Islam peribadahan every day. But of course this can feel happy for them direngkuh believe 100 percent that will guide the content of the life of Islam . Read More..

FAILURE NOT ANY OBSTACLES
Failure is a label that often we connect with an action that is not successful, and so applied, the label is to make people who said we could not afford. This is the spirit lower our people to become successful. At the moment we are still small, the failure does not have meaning, because we do not have the concept of "failure". If we have the concept of failure, then we will not be able to speak, will not be able to write and will not be running. Due to speak, write and walk through failure that must be incalculable amount. Similarly in the business world can also emulate a failure in our infancy and we can learn from the failure. Coca-Cola experienced a failure in the first year of sales. Sales made by Coca-Cola beverages in place in the front desk and spend 73.96 dollars to the campaign through banner ads and coupons. Failure to make the Coca-Cola to create awareness of other media, the mass media, which have more strength disbanding other media at that time and promote Coca-Cola with the atmosphere of merriment. Matsushita accounted for the first time is a plug adapter. This adapter has indeed diusulkannya to her employer earlier but did not get a response. To create this product, along with four Matsushita i take four months. Once the product is so, it appeared that no one would buy this product. In 1993, Compaq, which at the time as the sale of the PC market leaders, through cutting the price to rival Dell. The result Dell Computer suffer losses 65 million dollars in the first six months, which caused almost bankrupt. Dell to learn from failure. He tried to find other ways to sell computers. Dell eventually make a very fundamental change in business process re-engineering that is called. in the business introduce the E-Commerce. In 1999, Dell can sell 1.7 million dollars per day through the site E-Commercnya. Dell shares rose 2,000 percent in two years. Dell is able to compete with world-class companies such as IBM, Compaq, HP, and Bell-NEC. Even the market share and profits continue to increase and eventually become the largest PC seller in the world. When I started the business with friends, I experienced repeated failure of the back. I started with the failure of a book salesman, salesmen telex by phone, and car salesmen pengkilap materials. Primagama that only get 2 students in this campaign has been doing quite frequently. CV. Wijaya, the company that serves the car care services, which eventually die. Similarly start a business center computer education "IMKI", only 3 students and AMIKOM trusted by only 6 students. I'm with friends to try to learn from failure, and then make corrections and fix mecoba to achieve success | ||
