Researches at Johns Hopkins University's. Applied Physics laboratory ( APL) in Laurel , Maryland have designed a new human-like robot, Its name is Robo Sally. The machine can be controlled from a distance and can he used to do work that is dangerous for human beings.

Roho Sally has two long arms with human-like hands. She can use her fingers to pick up small objects .examine them in detail and do most things that human hands can do Each finger contains a tiny motor capable of squeezing 20 pounds of pinch foree ,.enough to defuse a bomb under the direction of an operator. She sits on a metal base with wheels that let her move around. turn in tight spaces and climb over small objects, .

Mike McLoughlin is the main investigator for the Applied Physics Laboratory's Prosthetics Program. "The purpose of that program is to develop prosthetic arms that have all the capability of your natural arms .and you do all the complex motions that we can do with the natural arm- with the robot. "

It was a difficult job. Mr. McLoughlin says the device had to have many small motors to. have the ability to do what a human hand does; It also needs to have human-like strength. The thumb was especially difficult because it permits the hand .to hold objects. And everything had. to fit into a space about the size of a human hand.

The next problem .he says .was to figure out how to control the artificial hand. " So we had to figure out how to make the connection between the brain and this arm.

For search-and-rescue duties.Roho Sally will be operated by a human being using a wire- less machine that is far from the robot. The operator will also wear special gloves and glasses. The glasses permit the operator to see the robot's hands .even though they are far away.

Mr. McLoughlin says this kind of robots could be used in what he calls "dull , dirty or dan- gerous" situations where fine human finger movements are required. He says the technology is not ready for everyday application .but he predicts that within five years we will see some won- derful improvements.

Braille is a tactile writing system used by people who are blind or visually impaired. It is traditionally written with embossed paper. Braille users can read computer screens and other electronic supports thanks to refreshable braille displays. They can write braille with the original slate and stylus or type it on a braille writer, such as a portable braille notetaker or computer that prints with a braille embosser.

Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at age 15, he developed a code for the French alphabet as an improvement on night writing. He published his system, which subsequently included musical notation, in 1829. The second revision, published in 1837, was the first binary form of writing developed in the modern era.

Braille characters are rectangular blocks called "cells" containing tiny bumps called "raised dots". The number and arrangement of these dots distinguish one character from another. Since the various braille alphabets originated as transcription codes for printed writing, the mappings (sets of character designations) vary from language to language. Furthermore, in English Braille there are three levels of encoding: Grade 1 a letter-by-letter transcription used for basic literacy; Grade 2 an addition of abbreviations and contractions; and Grade 3 various non-standardized personal shorthands. What are the answers to this following set of questions: 1. Who came up with Braille?
2. Is it named for him?
3. When was he trying to make night writing better?
4. What did his code represent?
5. How old was he then?

Spain, officially the Kingdom of Spain (), is a sovereign state located on the Iberian Peninsula in southwestern Europe, with two large archipelagoes, the Balearic Islands in the Mediterranean Sea and the Canary Islands off the North African Atlantic coast, two cities, Ceuta and Melilla, in the North African mainland and several small islands in the Alboran Sea near the Moroccan coast. The country's mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar; to the north and northeast by France, Andorra, and the Bay of Biscay; and to the west and northwest by Portugal and the Atlantic Ocean. It is the only European country to have a border with an African country (Morocco) and its African territory accounts for nearly 5% of its population, mostly in the Canary Islands but also in Ceuta and Melilla.

With an area of , Spain is the largest country in Southern Europe, the second largest country in Western Europe and the European Union, and the fourth largest country in the European continent. By population, Spain is the sixth largest in Europe and the fifth in the European Union.
