1. A self-propelled hospital bed navigation control system, comprising:

  • an operator-guided vehicle navigation controller includingone or more sensors operable to detect at least one human operator within an operator-guide zone associated with a self-propelled operator-guided hospital bed havinga bedframe structure including a surface configured to support an individual subject,a plurality of rotatable members operable to frictionally interface the self-propelled operator-guided hospital bed to a travel path and to move the self-propelled operator-guided hospital bed along the travel path,a steering assembly operable to vary a steering angle of at least one of the plurality of rotatable members,a power source, anda motor for driving one or more of the plurality of rotatable members,the operator-guided vehicle navigation controller operable to provide one or more control signals to navigate the self-propelled operator-guided hospital bed to a target location based on one or more inputs indicative of a change in health status of the individual subject; and

    an operator movement mapping module operably coupled to the operator-guided vehicle navigation controller and to at least one of the plurality of rotatable members, the power source, and the motor;

    the operator movement mapping module configured tomap one or more physical movements of the at least one human operator within the operator-guide zone to at least one input correlated with one or more navigation control commands for controlling the self-propelled operator-guided hospital bed, andgenerate a control signal to at least one of the plurality of rotatable members, the power source, and the motor to navigate the self-propelled operator-guided hospital bed based on the one or more navigation control commands.
