A study of the kinematic characteristics of a three degree-of-freedom (dof) parallel
mechanism is presented. The architecture of the mechanism is comprised of a mobile
platform attached to a base through three identical prismatic-revolute-spherical jointed
serial linkages. The prismatic joints are considered to be actuated. These prismatic ac-
tuators lie on a common plane and have radial directions of action. The mechanism’s
inverse displacement solution is obtained. Since the mechanism has only 3 dof, constraint
equations describing the inter-relationship between the six motion coordinates are de-
rived. These constraints allow the definition of parasitic motions, i.e., motions in the three
unspecified motion coordinates. Architecture optimization of the device is undertaken
demonstrating that specific values of design variables allow minimization of parasitic
motion. @S1050-0472~00!00101-X#
