Claim 17:
18. A method of operating a robot apparatus, comprising:
rotating an upper arm of a robot apparatus about a first rotational axis;
rotating a forearm relative to the upper arm and about a second rotational axis spaced from the first rotational axis;
rotating a first wrist member coupled to a first end effector and a second wrist member coupled to a second end effector relative to the forearm and about a third rotational axis spaced from the second rotational axis to a first end effector distance between the first end effector and the second end effector while the first end effector and the second end effector are extended a first distance from the first rotational axis to concurrently enter adjacent slit valves of a processing chamber; and
dependently rotating the first wrist member and the second wrist member in relation to each other about the third rotational axis to a second end effector distance while the first end effector and the second end effector are extended a second distance from the first rotational axis to concurrently place substrates on adjacent processing locations within the processing chamber, wherein the first end effector distance is different than the second end effector distance.
