Abstract: The present disclosure provides a navigation method and system which does not require a remotely located tracking system, or additional targets or other devices to be installed on the patient or object being tracked. The system uses one flexible component in physical contact with the patient/object and measures relative position as a function of forces that are generated by the flexing component as it is bent. The system translates forces into navigational commands for a robot, other manipulator, or for human manual navigation. A method for transforming a pre-planned motion pathway into a sequence of forces for this mode of navigation is also described. This system is also applicable in the field of manufacturing robotics, where the locations of objects or assemblies may not be precisely known or constant. The method and system disclosed herein can be used to maintain known position of an object/assembly or to navigate movement of a robot relative to an object/assembly as in the case of machining.

Abstract: Systems, methods, and devices relating to a sensor array for use with a user's finger segment and which indirectly maps the topography of a surface under the finger segment. Each sensor array is worn on a user's finger segment and has multiple sensitive strain gauges as well a positioning sensor. The multiple strain gauges are deployed around the periphery or sides of the finger segment. Each strain gauge measures the deformation of the finger segment pad as the finger segment passes over the surface topography. The relative ratios of the deformation detected indicates the location of a feature or contact point on the topography relative to the group of strain gauges. The positioning sensor determines the array's orientation as well as its location relative to a predetermined global reference frame.
