## Background
CLAIM OF PRIORITY
This application is the National Stage of International Application Serial No. PCT/GB2013/052989, filed Nov. 13, 2013, which claims the benefit of United Kingdom Application Serial No. GB1220401.2, filed Nov. 13, 2012, the entire disclosures of which are incorporated by reference herein.
BACKGROUND
The present invention relates to a combined multi-axial manipulator and guided vehicle. Particularly, though not exclusively, the present invention relates to a combined multi-axial manipulator and guided vehicle for use in the industrial, simulation, medical, entertainment and/or amusement industries. The combined multi-axial manipulator and guided vehicle may be used to carry passengers. Alternatively, the combined multi-axial manipulator and guided vehicle may be used to carry equipment such as, for example, still or moving image recording apparatus, still or moving image projection apparatus, scenery or prop items, or visual effects equipment.
Passenger carrying manipulators are well known, and are exemplified in the current art by, for example, U.S. Pat. No. 6,871,596 and U.S. Pat. No. 6,776,722 and have been effectively adopted in the simulation, research, medical and entertainment industries.
The art is however limited to the motion envelope provided by the reach of the manipulator system. Such limitations had been sought to be mitigated by the addition of open or closed loop track solutions, and have proved to be successful in expanding both the operational volume and passenger capacity of such solutions. The motion range remains however restricted to the provision of complex and substantial track infrastructure to facilitate such increases in motion ranges. The provision of such track hardware additionally limits the flexibility and adaptability of such motion ranges.
The invention seeks to redress this limitation by adapting such a passenger carrying purpose with a trackless passenger moving means by incorporating a passenger carrying manipulator with a trackless guided vehicle, such that the integrated system can perform passenger-carrying operations without the limitation of such track hardware or related infrastructure.
According to the present invention there is provided an autonomously guided vehicle for use in the industrial, simulation, medical, entertainment or amusement industries comprising:
