Self-contained, remotely operated, mobile measurement and inspection systems for stand-off inspection of large target objects located at sites distant from an operations center. The systems comprise a mobile platform with on-board instrumentation capable of making dimensional measurements in the local coordinate system of the target object. The systems comprise multiple hardware and software components networked to a control interface that enables the operator at the operations center to teleoperate the equipment. Various embodiments include rough-terrain and floatable mobile measurement and inspection systems.
