Workspaces of a walking machine and their graphical representation. Part I: kinematic workspaces

This paper addresses the kinematic workspaces of a walking machine and their graphical representation. The workspaces for walking machines are defined and the methods for investigating various workspaces are presented ; the kinematic workspace constraints are established ; the displacement is analysed ; an algorithm for investigation of kinematic workspaces is presented ; and the position and orientation kinematic workspaces are analysed and graphically represented for an example walking machine design.
