  2. 2. INTRODUCTION TO LEGO • Lego[a] is a popular line of construction toys manufactured by The Lego Group, a privately held company based in Billund, Denmark. • The company's flagship product, Lego, consists of colourful interlocking plastic bricks and an accompanying array of gears, minifigures and various other parts. • Lego bricks can be assembled and connected in many ways, to construct such objects as vehicles, buildings, and even working robots. • Anything constructed can then be taken apart again, and the pieces used to make other objects. Lego began manufacturing interlocking toy bricks in 1949. • Since then a global Lego subculture has developed, supporting movies, games, competitions, and six themed amusement parks.
  3. 3. HISTORY AND DEVELOPMENT 1890s–1950s • The Lego Group began in the workshop of Ole Kirk Christiansen (born 7 April 1891), a carpenter from Billund, Denmark, who began making wooden toys in 1932.In 1934, his company came to be called "Lego", from the Danish phrase leg godt, which means "play well". • It expanded to producing plastic toys in 1947. • In 1949 Lego began producing, among other new products "Automatic Binding Bricks". These bricks were based in part on the Kiddicraft Self- Locking Bricks, which were patented in the United Kingdom in 1939 and then there released in 1947. • Lego modified the design of the Kiddicraft brick after examining a sample given to it by the British supplier of an injection- molding machine that the company had purchased. • The bricks, originally manufactured from cellulose acetate.
  4. 4. 1960s – 21st century  Since the 1960s, the Lego Group has released thousands of sets with a variety of themes, including town and city, space, robots, pirates, trains,Vikings, castle, dinosaurs, undersea exploration, and wild west.  In 1978, Lego produced the first mini figures, which have since become a staple in most sets  Even used in the sets of Star wars, Indiana Jones andToy Story making it very realistic  In May 2011, Space Shuttle Endeavour mission STS-134 brought 13 Lego kits to the International Space Station, where astronauts will build models and see how they react in microgravity, as part of the Lego Bricks in Space program. The results will be shared with schools as part of an educational project
  5. 5. DESIGN • Lego pieces of all varieties constitute a universal system. Despite variation in the design and purpose of individual pieces over the years, each remains compatible in some way with existing pieces. • Each Lego piece must be manufactured to an exacting degree of precision.When two pieces are engaged they must fit firmly, yet be easily disassembled.The machines that make Lego bricks have tolerances as small as 10 micrometres • As of September 2008 the design teams use 3D modelling software to generate CAD drawings from initial design sketches.The designs are then prototyped using an in-house stereolithography machine.
  6. 6. MANUFACTURE • Since 1963, Lego pieces have been manufactured from a strong, resilient plastic known as acrylonitrile butadiene styrene (ABS) • As of September 2008, the engineers use the NX CAD/CAM/CAE PLM software suite to model the elements. The software allows the parts to be optimised by way of mould flow and stress analysis. • Manufacturing of Lego bricks occurs at a number of locations around the world. Moulding is done in Billund, Denmark; Nyíregyháza, Hungary; andMonterrey, Mexico.
  7. 7. TECHNOLOGICAL ADVANCEMENTS WITH LEGO Robotics sets  Lego initiated a robotics line of toys called 'Mindstorms' in 1998, and has continued to expand and update this range ever since.  There are several robotics competitions which use the Lego robotics sets. The earliest is Botball, a national U.S. middle- and high-school competition stemming from the MIT 6.270 Lego robotics tournament.  Merlin Entertainments operates six Legoland amusement parks, the original in Billund, Denmark, the second in Windsor, England, the third inGünzburg, Germany, the fourth in Carlsbad, California, the fifth in Winter Haven, Florida, and the sixth in Nusajaya, Malaysia
