A wagon (also alternatively and archaically spelt waggon in British and Commonwealth English) is a heavy four-wheeled vehicle pulled by draught animals or on occasion by humans (see below), used for transporting goods, commodities, agricultural materials, supplies and sometimes people. Wagons are immediately distinguished from carts (which have two wheels) and from lighter four-wheeled vehicles primarily for carrying people, such as carriages. Wagons are usually pulled by animals such as horses, mules or oxen. They may be pulled by one animal or by several, often in pairs or teams. However, there are examples of human-propelled wagons, such as mining corfs. A wagon was formerly called a wain and one who builds or repairs wagons is a wainwright. More specifically, a wain is a type of horse- or oxen-drawn, load-carrying vehicle, used for agricultural purposes rather than transporting people. A wagon or cart, usually four-wheeled; for example, a haywain, normally has four wheels, but the term has now acquired slightly poetical connotations, so is not always used with technical correctness. However, a two-wheeled "haywain" would be a hay cart, as opposed to a carriage. Wain is also an archaic term for a chariot. Wain can also be a verb, to carry or deliver, and has other meanings. The wagon has four wheels made out of wood and steel. The wagon wheel had an average weight of upwards of 300 pounds. The wagon wheels had a steel outer edge of about 1 inch thick and a wooden inner edge of about two inches thick. There are up to 40 spokes in an average wagon wheel all made out of wood. There are two steel rings around the middle of the wheel to hold the spokes on the wheel. A person who drives wagons is called a "wagoner", a "teamster", a "bullocky", a "muleskinner", or simply a "driver".

A walker or walking frame is a tool for disabled or elderly people who need additional support to maintain balance or stability while walking. In the United Kingdom, a common equivalent term for a walker is Zimmer frame, a genericised trademark from Zimmer Holdings, a major manufacturer of such devices and joint replacement parts. Walkers started appearing in the early 1950s. The first US patent was awarded in 1953 to William Cribbes Robb, of Stretford, UK, for a device called "walking aid", which had been filed with the British patent office in August 1949. Two variants with wheels were both awarded US patents in May 1957, and the first non-wheeled design that was called a "walker" was patented in 1965 by Elmer F. Ries of Cincinnati, Ohio. The first walker to resemble modern walkers was patented in 1970 by Alfred A. Smith of Van Nuys, California.

Walkers are vehicles from the Star Wars universe that traverse the landscape on mechanical legs. The AT-at is the four leg Star Wars walker showed in the 5 movie of the Star Wars and it was showed at it attack the rebels on the planet hoth. ((They was not used by the old republic the At-Te was the republic walker)) The Galactic Empire used the At-at for ground assault or transport. Throughout the saga, walkers have played a pivotal role in the fate of characters and the outcome of battles. Industrial Light and Magic (ILM) is responsible for their animation and design, often using models, stop-motion animation, and relevant matte paintings to depict their presence in the films. There are a variety of walkers: The Empire Strikes Back introduces the All Terrain Armored Transport (AT-AT) and All Terrain Scout Transport (AT-ST). The Prequel Trilogy, Star Wars: Episode II – Attack of the Clones and Star Wars: Episode III – Revenge of the Sith introduced earlier models of walkers, such as the AT-TE, and the Star Wars expanded universe features numerous others. Walker variants have been merchandised and featured in popular culture.

Walkman is a Sony brand tradename, originally used for portable audio cassette players from the late 1970s onwards. In later years, it has been used by Sony to market digital portable audio/video players, as well as a line of mobile phones introduced in 2005. The original Walkman cassette player, released in 1979, changed music listening habits by allowing people to listen to their music whilst on the move. This could turn everyday tasks like commuting and running into pleasurable experiences, give commuters a sense of privacy, and add a soundtrack to urban surroundings. The Walkman was devised by Sony co-founder Masaru Ibuka, and first built by audio-division engineers Nobutosi Kiraha and Kozo Osohne in 1979. Ibuka loved listening to opera on his frequent trans-Pacific flights, but felt Sony's existing portable player - the notebook-sized, five pound TC-D5 - was far too unwieldy for everyday use, and far too expensive to ever sell successfully. Sony thus began work on a portable player that could combine light weight and stereo sound with a price an ordinary consumer could afford. The original prototype was built from a heavily modified Sony Pressman, a lightweight, compact tape recorder designed for journalists. By replacing the recording head with a playback head, and the speaker with an amplifier, Sony engineers were able to combine the portability of the Pressman with the stereo experience of the TC-D5. By using lower-end components to reduce the price, and enclosing the parts in an attractive casing, they had solved Ibuka's challenge. The original idea for a portable stereo is ultimately credited to Brazilian-German inventor Andreas Pavel, who patented the Stereobelt in 1977. Though Sony agreed to pay Pavel royalties, it refused to recognize him as the inventor of the personal stereo until a legal settlement in 2003. The player was released in Japan in 1979 as the "Walkman", a nod to the player's ancestor, the Pressman. This was followed by a series of international releases under several other names - "Soundabout" in the United States, "Freestyle" in Sweden, and "Stowaway" in the UK. Overseas sales companies objected to the name “Walkman” as they felt it was too much of a Japanese-English name, and proposed others. Sony America initially suggested “Disco Jogger”, which was not chosen because it would have limited appeal. Eventually "Walkman" caught on globally and Sony used the name worldwide. The names "Walkman", "Pressman", "Watchman", "Scoopman", "Discman", and "Talkman" are trademarks of Sony, and have been applied to a wide range of portable entertainment devices manufactured by the company. Sony continues to use the "Walkman" brand name for most of their portable audio devices, after the "Discman" name for CD players was dropped in the late 1990s.

A wall is a structure that defines an area, carries a load, or provides shelter or security. There are many kinds of walls: Defensive walls in fortification Walls in buildings that form a fundamental part of the superstructure or separate interior sections, sometimes for fire safety Retaining walls, which hold back dirt, stone, water, or noise sound Walls that protect from oceans (seawalls or rivers levees) Permanent, solid fences Border barriers between countries Brick wall Stone wall Glass wall (only when most of the wall, in smaller amounts it is called a window) Doors are mobile walls on hinges which open to form a gateway.

WALL-E (stylized with an interpunct as WALL·E) is a 2008 American computer-animated science fiction film produced by Pixar Animation Studios for Walt Disney Pictures. It was directed and co-written by Andrew Stanton, produced by Jim Morris, and co-written by Jim Reardon. It stars the voices of Ben Burtt, Elissa Knight, Jeff Garlin, Fred Willard, John Ratzenberger, Kathy Najimy, Sigourney Weaver, and the MacInTalk system, and was the overall ninth feature film produced by the company. It follows a trash compactor robot in a deserted world, left to clean a largely abandoned city. However, he is visited by a probe sent by the Axiom ship, whom he falls in love with and pursues across the galaxy. After directing Finding Nemo, Stanton felt Pixar had created believable simulations of underwater physics and was willing to direct a film set largely in space. WALL-E has minimal dialogue in its early sequences; many of the characters do not have voices, but instead communicate with body language and robotic sounds designed by Burtt. The film criticizes consumerism, corporatism, nostalgia, waste management, human environmental impact and concerns, obesity, and global catastrophic risk. It is also Pixar's first animated film with segments featuring live-action characters. Following Pixar tradition, WALL-E was paired with a short film titled Presto for its theatrical release. WALL-E was released in the United States and Canada on June 27, 2008. It was an instant blockbuster, grossing $533.3 million worldwide over a $180 million budget, receiving overwhelming acclaim from critics, and winning the 2008 Golden Globe Award for Best Animated Feature Film, the 2009 Hugo Award for Best Long Form Dramatic Presentation, the final Nebula Award for Best Script, the Saturn Award for Best Animated Film and the Academy Award for Best Animated Feature with five nominations. The film also topped Time's list of the "Best Movies of the Decade", and in 2016 was voted 29th among 100 films considered the best of the 21st century by 117 film critics from around the world.
