ABSTRACT:
A durable, frictionless remote controlled manipulator, which is compact, stable, easy to construct, and has good dynamic capability, is a cradle suspension of lever arms, joined by crossed spring hinges to form a parallelogram suspension. The suspension creates vertical motions that have minimal cross-coupled horizontal error. Vertical cross-coupling error that arises at the extremes of parallelogram displacement in the two horizontal axes is hydraulically corrected by the remote controller. Thus, displacements are more nearly mutually perpendicular, and the position of the microtool more faithfully corresponds to the micromter settings. Being compact, the device can be mounted on a microscope stage to minimize cantilevering of the microtool, which is an unwanted source of vibration and also limits the load bearing in larger devices that can only be placed alongside the microscope.
