The overhead hoist transport vehicle of claim 1, wherein the gripper is further configured to move in a downwards vertical direction towards a process tool load port of a process tool on an integrated circuit chip manufacturing floor and to place the material unit on the process tool load port. 3. The overhead hoist transport vehicle of claim 2, wherein the gripper is further configured to retract to a starting position after placing the material unit on the process tool load port. 4. The overhead hoist transport vehicle of claim 3, wherein the process tool load port is an interface where a material unit is exchanged between an automated material handling system and the process tool. 5. The overhead hoist transport vehicle of claim 1, wherein the wherein the movable stage and the gripper are configured to work in concert to move the gripper to a storage location directly below the overhead hoist transport vehicle. 6. The overhead hoist transport vehicle of claim 1, wherein the hoist is configured to move the gripper vertically when the moveable platform is in the retracted position. 7. The overhead hoist transport vehicle of claim 1, wherein the moveable stage is configured to move the gripper without rotation or angular displacement. 8. The overhead hoist transport vehicle of claim 1, wherein the material unit is a front opening unified pod. 9. The overhead hoist transport vehicle of claim 1, wherein the moveable stage and the hoist are configured to work in concert to move the gripper gripping the material unit from a first position proximate to the overhead hoist transport vehicle to at least one of a second position proximate to a process tool load port and a third position proximate to a storage location, the movement of the moveable stage and the hoist allowing the overhead hoist transport vehicle to load the material unit on at least one of the process tool load port and the storage location. 10. The overhead hoist transport vehicle of claim 1, wherein the overhead hoist transport vehicle is configured to couple to an overhead rail in a semiconductor fabrication plant. 11. An overhead hoist transport (OHT) vehicle comprising: a gripper configured to hold a material unit;a moveable stage coupled to the gripper, wherein the moveable stage is configured to extend from a retracted position in the vehicle to an unretracted position outside the vehicle, and thereby move the gripper along a horizontal axis from a first position beneath an overhead rail to a second position adjacent to a side of the OHT vehicle; anda hoist coupled to the movable stage and to the gripper, with the hoist being configured to retract with the moveable stage into the vehicle, wherein the hoist is configured to move the gripper along a vertical axis to a position that is directly below the moveable stage in the unretracted position;wherein the OHT vehicle is configured in the retracted position of the moveable stage to carry the material unit beneath the overhead rail in a semiconductor fabrication plant;wherein the moveable stage is further configured to extend a distance greater than the width of the material unit laterally from a retracted position along a single axis to a first side of the OHT and to extend a distance greater than the width of a material unit laterally from the retracted position along the single axis to a second side of the OHT vehicle. 12.
