The origin may be Dutch or German as Walker is the modern German for 'Fuller,' with weavers fleeing religious persecution in North West Europe settling along the North Eastern English coast (cf the town of Walker near Newcastle). The name is also found within African Kenyan tribes.

Walker is a 1987 American- Mexican Acid Western film directed by Alex Cox and starring Ed Harris, Richard Masur, Rene Auberjonois, Peter Boyle, Sy Richardson, Xander Berkeley, Alfonso Arau, Marlee Matlin and Miguel Sandoval. The film is based on the life story of William Walker (1824–1860), the American filibuster who invaded Mexico in the 1850s and made himself President of Nicaragua shortly thereafter. It was written by Rudy Wurlitzer and scored by Joe Strummer, who also plays a small role as a member of Walker's army.

The film is intentionally full of anachronisms such as helicopters, Zippo lighters, automatic rifles and a car passing a horse carriage. It was filmed in Nicaragua during the Contra War.

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.

In BEAM robotics, a walker is a walking machine that has a driven mode of locomotion by intermittent ground-contacting legs. They usually possess 1 to 12 (generally, three or less) motors. "Muscle wired" walkers utilizes Nitinol (nickel - titanium alloy) for its actuators.

BEAM walking robots contain Nv networks, which consist of NV neurons each of which is a very simple oscillator setup. The most common form of BEAM walker is the master slave Bicore, which uses two suspended Bicore arrangements.

A BEAM walker does not use a processor, nor is it programmed in any way—it walks and responds to terrain via resistive input from its motors. This is an extremely clever method for creating locomotion.

Walkers are fictional vehicles from the Star Wars universe that traverse the landscape on mechanical legs. They are used by the Old Republic and the Galactic Empire 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). In 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. The Star Wars expanded universe features numerous others. Walker variants have been merchandised and featured in popular culture.
