1. A robotic retrieval vehicle comprising:
a first portion comprising:
a first mechanism that facilitates vertical movement of the robotic retrieval vehicle along a vertical shaft of a high density storage system, wherein the first mechanism comprises a drive mechanism configured to raise or lower the robotic retrieval vehicle in the vertical shaft, wherein the drive mechanism is positioned at a location other than a corner of the first portion; and
a second drive mechanism that facilitates lateral movement in the high density storage system, wherein the second drive mechanism comprises a set of four wheels that can maneuver the robotic retrieval vehicle on a rail network in the high density storage system and can maneuver the robotic retrieval vehicle in a first direction and a second direction orthogonal to the first direction; and
a second portion that is rotatable relative to the first portion.
