A vertical actuator mechanism for the legs of a walking machine, including four links arranged in a pantograph mechanism, with one corner of the pantograph providing the main mounting point for each leg, which permits the use of swinging links in the vertical actuator mechanism and retains complete isolation between the vertical and horizontal drive mechanisms. Vertical actuation of the pantograph mechanism is accomplished by means of a pair of long, swinging struts connected between a drive nut mounted on a lead screw and a point on the pantograph mechanism. The struts are connected to the pantograph mechanism at a location other than the true pantograph point, the point being selected so that the foot moves approximately linearly as the strut pivots around the drive nut. |
