The stimulus for this paper is the expressed need in proposals for legged vehicles both to propel the vehicle in rectilinear translation parallel to the mean ground-profile beneath it and to allow the chassis-height to be adjustable. Energy considerations point toward having a single propulsion-actuator on each leg-linkage rather than adopting the less economical option of simultaneous actuation at two or more serially connected leg-joints. Of the linkages whose kinematics are here studied some relate more closely to legged vehicles than others do; the paper should be viewed in a general rather than a specific context. Exact and approximate straight-line planar linkages are covered. Derivatives of Richard Roberts’s linkage are put forward as those that are the most promising adjustable linkages whose joints are all turning pairs.

Cut And Fill

A method for simplifying irregular ground profile of roadway cross sections by a straight line is presented. The presented method does not affect the accuracy of earthwork volume computations. Two types of cross sections are considered: cut (or fill) and transition sections. For a cut (or fill) section, the simplified section is designed such that its area equals that of the original section. This is accomplished by adjusting the least-squares (LS) parameters. Three cases of adjustments that depend on the area of the original section and the unadjusted LS parameters are presented. These cases preserve the section type (cut or fill) and, as much as possible, the general shape of the original section. For a transition section, the simplified section is designed such that its cut and fill areas equal those of the original section. These conditions of equal areas are used to develop formulas for designing the simplified section directly. Application of the method is illustrated by numerical examples. Key words: roadway, cross section, irregular, least squares, linear profile, earthwork volume.

Leg Prosthesis

The field of control of powered lower-leg prostheses has advanced due to the improvements in sensors and computational power. Much effort has been done to improve the capabilities of prostheses, such as mimicking the stiffness, weight, and mobility of a human ankle-foot [1] and autonomously commanding the robotic prosthesis for gait [2].
