Hello everybody and Mr Fernandez i am very excited about the fireworks it is very fun to edit pictures and do very fun things in the fireworks and i am mentioning the debate between jaleed and ahmad i think that these both were pretty awesome because they were not just repeating the notes but they were actually doing live debate and now i have much left to say and goodbye
IF YOU fancy an extra pair of hands, why not take a leaf out of Dr Octopus’s book? A pair of intelligent arms should make almost any job a lot easier.
The semi-autonomous arms extend out in front of the body from the hips and are strapped to a backpack-like harness that holds the control circuitry. The prototype is the handiwork of Federico Parietti and Harry Asada of the Massachusetts Institute of Technology, who suggest that one of the first uses could be to help factory workers, or those with tricky DIY tasks to perform.
“It’s the first time I’ve seen robot arms designed to augment human abilities. It’s bold and out of keeping with anything I’ve ever seen to attach two arms to a human,” says Dave Barrett, a roboticist and mechanical engineer at Olin College in Needham, Massachusetts.
So how are the arms controlled? Parietti and Asada designed the limbs to learn and hopefully anticipate what their wearer wants. The idea is that the algorithms in charge of the limbs would first be trained to perform specific tasks.
To demonstrate what the prototype can do, a camera observed a pair of workers helping each other drill into a loose metal plate. The camera measured the distances between the tools and work surface, while feedback from sensors on the workers’ bodies tracked their movements. This taught the arms where to grab and how much force to apply, so it could then assist a lone worker to both hold the drill and secure the plate.
If you think the idea of free-roaming robotic arms holding power tools sounds alarming, you aren’t alone. “If a robotic arm can do useful work, it can also hurt you badly,” says Barrett. “Traditionally, people are kept far away from robot arms because the arms are dangerous. The concept of strapping robotic arms onto a person is terrifying,” he says.
Parietti and Asada have tried to address some of those safety fears by building the arms from softer material. Flexible components in the robotic arm, called series elastic actuators – invented in the 1990s by Gill Pratt and Matt Williamson at MIT – mean that less damage will be done if the arms do lose control.
Dennis Hong at Virginia Tech in Blacksburg says that roboticists have spent the last 30 years attempting to make robots more rigid, but now understand they need compliance and springiness to operate safely alongside humans. He says he has never come across robotic arms designed to be worn on the body.
The limbs were described at the Dynamic Systems and Control Conference in Florida last week. Funded by Boeing, their first use could be to help workers build aircraft. The broader goal, say the researchers, is for the limbs and their users to work seamlessly so that “humans may perceive them as part of their own bodies”.
The robotic hands were known only as a fiction but now it has become a reality and it is actually is pretty cool and awesome and it can do pretty much work that is very hard for humans.
This legendary invention could absolutely change the way we live and it will have a very massive effect on the military because the soldiers can use this technology to shoot the enemy without even putting their hands in risk and it can be used in warehouses .
Hello world this week was much serious than fun because the teacher told us about much dangerous people who just hack other people accounts just for fun and some do it for sake of money and the teacher showed us a video about the “mafia boy” the boy who hacked all the important networks just at the age of 15 i think it was pretty tough for him to admit that he had brought down yahoo by himself and i think it was pretty cool and also fun to be computer expert just at the age of 15 however this week was also fun like usual and bye.
this week was very fun because this week we did the typing practice because most of us had horrible typing like me and this week the teacher also told us about the implications of using facebook and its impacts and about the people who can track us if we have not enabled privacy everybody can track us and and i also checked my password strength and it was pretty awesome and it said it will take a thousand years to crack it
and i have not too much to say now goodbye
Flying cars aren’t just science fiction anymore.
Woburn, Massachusetts-based Terrafugia Inc. said that its prototype flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year.
The vehicle – dubbed the Transition – has two seats, four wheels and wings that fold up so it can be driven like a car. Last month, it flew at 1,400 feet for eight minutes. Commercial jets fly at 35,000 feet.

Around 100 people have already put down a $10,000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don’t expect it to show up in too many driveways. It’s expected to cost $279,000.
And it won’t help if you’re stuck in traffic. The car needs a runway.
The flying car has always had a special place in the American imagination. Inventors have been trying to make them since the 1930s, according to Robert Mann, an airline industry analyst who owns R.W. Mann & Co. in Port Washington, New York.
But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The government has already granted the company’s request to use special tires and glass that are lighter than normal automotive ones, to make it easier for the vehicle to fly.
The government has also temporarily exempted the Transition from the requirement to equip vehicles with electronic stability control, which would add about six pounds to the vehicle. The Transition is currently going through a battery of automotive crash tests to make sure it meets federal safety standards.
Mann said Terrafugia was helped by the Federal Aviation Administration’s decision five years ago to create a separate set of standards for light sport aircraft. The standards govern the size and speed of the plane and licensing requirements for pilots, which are less restrictive than requirements for pilots of larger planes.
Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a relatively low hurdle for pilots.
The Transition can reach around 70 miles per hour on the road and 115 in the air, spokesman Steven Moscaritolo said. It flies using a 23-gallon tank of automotive fuel and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.
Mann questions the size of the market for the Transition. The general aviation market has been in decline for two decades, he said, largely because of fuel costs and the high cost of liability for manufacturers. Also, fewer people are learning how to fly.
‘This is not going to be an inexpensive aircraft to produce or market,’ he said.
‘It has some uniqueness, and will get some sales, but the question is, could it ever be a profitable enterprise?’
Mann sees the western US as the most likely market, where people could fly instead of driving long distances.
Terrafugia has been working on flying cars since 2006, and has already pushed back the launch once. Last summer the company said it would have to delay expected 2011 deliveries due to design challenges and problems with parts suppliers.
With the appearance in New York, the company hopes to attract the eye of customers as well as investors.
‘We are introducing ourselves as a viable company to the automotive world,’ Moscaritolo said.
it is a technology that can change the way we live and it can also be very useful for business people who have to go on business meetings so it will be easy for them to travel to anywhere they want immedietly and because of this there will a decrease in traffic and it will be lot fun for a man who buys this car-plane.
IT will have a very massive effect on society because a lot of traffic will be converted into air traffic because all the rich people will buy it for their luxury and it will cause a very big problem to air planes because a lot of people will be in air cars but still it will be the best thing ever made.it will also rise up some serious issues such as does the driver has the required qualification for flying a car plane it will also require more air traffic controllers and it can also be used by criminals to escape the place after robbing it .however it is a great invention.
Hello Mr Fernandez this week was very hard because we had to work very hard to research on the topics the teacher had given us to research and present it on friday in the front of class and explaining all the questions the students will ask us and it is also very difficult for me because i have never done that before and it will be also very exciting because again i have never done that before now i have not much left to say ok then goodbye.
This week was very fun and also very frightening because today we discovered what lies beneath these very kind and good people who upload these “Torrents” they are actually like troy people who used the trojans to make them think that they are their friends but actually they were worst enemies like these the people who upload torrents seem to be very nice but in reality they are the people who actually want to hurt us and this we also learned that there are some people in this world who just want to hurt people for just fun
they can even take control of your computer.
