Walkers
They're propelled by legs which lift to make intermittent contact with the ground

Walkers are legged robots that lift their legs in sequence as they move. [画像:Fang's walker]There are a large number of walking BEAM robots around (you have to admit, they just plain look neat!). The simplest is based on a single motor, two legs, and a little "idler" wheel that's drug along behind -- go here for details.

The most common design by far is some variation or another on a theme -- a 4-legged, 2-motor robot. These rely on clever balance, and inter-motor timing to create a walking gait.

Less-common, but increasingly popular, are walkers with 3, 4, or even more motors. Obviously, the more motors a walker has, the more varied its behavior can be (but along with this comes an increase in both mechanical and electronic complexity, as well as cost).

I've got more-detailed information in subsequent sections on various designs; I've organized these sections according to the number of motors a given walker design uses (note that any one of these can have various numbers of legs).

Note that walker circuits are discussed over in the circuits library.
