Claim Text:
1. A robotic strong arm (RSA) for assisting in the transfer of a person from a first surface to a second surface, comprising: first and second members, wherein each member comprises a prismatic joint having first and second ends and comprising inner and outer shells and a motor for powered linear movement of the outer shell with respect to the inner shell; a first powered joint interconnecting the second end of the first member with the first end of the second member, wherein the first powered joint provides movement of the second member with respect to the first member; wherein the first end of the first member is attached to a rotatable base and wherein the rotatable base is movably attached for powered movement along a component associated with, and extending around at least a portion of a periphery about, the first surface; a computer controller for controlling movements of the outer shells, first powered joint, rotation of the rotatable base and movement of the rotatable base and RSA along the component; a sensor associated with one or both outer shells for sensing position information for one or both outer shells and providing said position information to the computer controller; and a user interface to the computer controller for inputting commands for movement of the RSA; wherein the computer controller detects an onset of a dangerous positioning of the RSA and warns the user before and/or during said dangerous positioning of the RSA.
