Abstract:
A multi-set robot adapted to transfer multiple substrates comprising:a first robot set comprising: a first motor coupled to a first rotatable member that is rotatable about an axis of rotational symmetry; a second motor coupled to a second rotatable member that is rotatable about the axis of rotational symmetry; a first plurality of blades vertically spaced from one another and each adapted to support a substrate; and a first linkage adapted to enable coordinated movement of the first plurality of blades on rotation of the first and second rotatable members; and at least a second robot set positioned above the first robot set comprising: a third motor coupled to a third rotatable member that is rotatable about the axis of rotational symmetry; a fourth motor coupled to a fourth rotatable member that is rotatable about the axis of rotational symmetry; a second plurality of blades vertically spaced from one another and each adapted to support a substrate; and a second linkage adapted to enable coordinated movement of the second plurality of blades on rotation of the third and fourth rotatable members.
