Six-degrees-of-freedom movement sensor having strain gauge mechanical supports

摘要: A user-manipulable sensor apparatus is provided for allowing a user to input, through hand manipulation of movable member, motion in six degrees freedom: translational the X, Y, and Z axes, rotation about each those three axes. The includes central member which acts as stationary reference, such spherical, hollow substantially surrounds member. Flexible wire or in-line strain gauges are coupled between inside surface hold quiescent position, relative position Accordingly, there no need additional support members holding position. Manipulation causes tension on various ones gauges. produce signals, from may be computed.
