a walking tool for old and slightly disabled people
a doll that walks. Can be a "head turning walker" with a head that rotates from side to side as her legs move. Some dolls are "pin jointed walkers" - there legs are attached by pins (or rods) at the hips.
A walker is a tool for disabled people who need additional support to maintain balance or stability while walking. It consists of a frame that is about waist high, approximately twelve inches deep and slightly wider than the user. Walkers are also available in other sizes such as Pediatric (for children) or Bariatric (for overweight or obese persons).
A walker is a vehicle that moves on legs rather than wheels or tracks. Walkers have been constructed with anywhere from one to over eight legs; common configurations are one leg Pogo stick (hopper), two legs (biped), four legs (quadruped) and six legs (hexapod). However, also worthy of mention within this category are the fictitious tripods that appear within H.
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 motors. (ed. motors numbering above 3 are uncommon) "Muscle wired" walkers ultilizes Nitinol (nickel - titanium alloy) for its actuators.
