Abstract:
1. A substrate transport apparatus comprising: a substantially rigid upper arm having a first upper arm section and a second upper arm section coupled to each other at a common axis of rotation by a releasable coupling to form the substantially rigid upper arm having opposing ends; a first forearm rotatably coupled to a first one of the opposing ends; a second forearm rotatably coupled to a second one of the opposing ends; and at least one end effector rotatably coupled to each of the first forearm and second forearm, each of the at least one end effector being configured to hold at least one substrate; wherein the releasable coupling is configured to change a size of an inclusive angle between the first upper arm section and the second upper arm section, where the inclusive angle is fixed for transporting substrates.
