An end effector for a robot arm couples to the arm at a mounting fixture.
The end effector includes a first paddle head assembly, the assembly
including a paddle head and a solenoid controlling extension and
retraction of the paddle head away from and toward the mounting fixture.
In addition, the effector includes a vacuum region positioned in the
first paddle head assembly adapted to receive a disk and coupled to an
extendable vacuum arm. A method for operating a dual paddle end effector
includes the steps of: connecting at least a first paddle head assembly
including a paddle head to a robotic arm; positioning the arm adjacent to
a disk in a carrier; and providing a vacuum suction to a vacuum region in
the paddle head assembly sufficient to lift the disk into the vacuum
region in the paddle head assembly.
