Electronic device manufacturing apparatus and robot apparatus are described. The apparatus are configured to efficiently pick and place substrates wherein the robot apparatus includes an upper arm and three blades B1, B2, B3 that are independently rotatable. The three blades are configured to service a first dual load lock and second dual load lock wherein each dual load lock includes a different pitch. In some embodiments, a first pitch P1 is smaller than a second pitch P2. Blades B2 and B3 (or optionally blades B1 and B2) can service the first dual load lock with Pitch P1 and blades B1 and B3 can service the second dual load lock including the second pitch P2. Methods of operating the electronic device manufacturing apparatus and the robot apparatus are provided, as are numerous other aspects.
