Real Walking Vehicles
There are a few prototypes of walking vehicles. Currently almost all of these are experimental or proof of concept, and as such may never see mass production.
A "walking vehicle" is a vehicle that moves on legs rather than wheels or tracks. Walking vehicles have been constructed with anywhere from one to more than eight legs. They are classified according to the number of legs with common configurations being one leg (pogo stick or "hopper"), two legs (biped), four legs (quadruped), and six legs (hexapod).
While the mobility of walking vehicles is arguably higher than that of wheeled or tracked vehicles, their inherent complexity has limited their use mainly to experimental vehicles. Examples of manned walking vehicles include General Electric's Walking truck, the University of Duisburg-Essen's ALDURO. Timberjack, a subsidiary of John Deere, built a practical hexapod Walking Forest Machine (harvester).
Some walking machines such as the BigDog have been designed by the military. The largest walking machine ever made is the Big Muskie dragline excavator, used primarily in mining operations.

Famous quotes containing the words real, walking and/or vehicles:
“No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.”
—T.S. (Thomas Stearns)
“A woman preaching is like a dog’s walking on his hinder legs. It is not done well; but you are surprised to find it done at all.”
—Samuel Johnson (1709–1784)
“Television programming for children need not be saccharine or insipid in order to give to violence its proper balance in the scheme of things.... But as an endless diet for the sake of excitement and sensation in stories whose plots are vehicles for killing and torture and little more, it is not healthy for young children. Unfamiliar as yet with the full story of human response, they are being misled when they are offered perversion before they have fully learned what is sound.”
—Dorothy H. Cohen (20th century)
