| Abstract: |
A three-axis machine is disclosed. The machine includes a machine component to which a workpiece or tool can be attached. An actuator, such as three powered extensible legs, is connected between the machine component and a support structure. Three control arms also are connected between the machine component and the support structure. Preferably, each control arm is pivotably connected to the support structure and the machine component and includes a pair of four-bar linkages connected in series. The control arms are oriented to permit rapid movement of the machine component along any or all of the three linear axes, while restricting rotational movement of the machine component along the rotational axes.

What is claimed:
1. A machine that can be mounted to a support structure, the machine being designed to move an object along a path with the potential motion of the object being defined by three linear axes and three rotational axes, comprising:
- a machine component configured to carry the object;
- an actuator connected to the machine component and configured for connection to the support structure to selectively move the machine component with respect to the support structure; and
- a rotational control system including a control arm having a first end attached to the machine component and a second end configured for pivotable attachment to the support structure, the control arm further including a pair of four bar linkages connected in series, the pair of four bar linkages of the control arm remaining oriented generally parallel to a common plane during movement of the machine component, wherein the control arm permits movement of the machine component along the three linear axes while preventing motion along at least two rotational axes.
