Abstract
A hermetically sealed multi-axis articulated arm apparatus for use within a sealable isolator chamber is disclosed. In one general aspect, it comprises a rotational shaft that passes through an opening in the chamber, a sealing member disposed within the chamber for sealing the shaft to an inner surface of the chamber, interconnected hermetically sealed arm segments operably attached to the linear motion shaft; an end effector operably attached to a terminal arm segment among the arm segments, and at least one fully enclosed drive system for driving and controlling the shaft and the arm segments. The rotational shaft can further be a linear motion shaft for which the sealing member is a bellows. The materials for the parts of the apparatus exposed to the atmosphere of the chamber can be compatible with an aseptic and cleanable environment and the surfaces of the arm segments can be shaped to avoid pooling of contaminants.
