ABSTRACT:
A force sensor is disclosed in which strain is measured exclusively by shear strain gages mounted on L or T-shaped legs. Each such leg has at least two arms which are orthogonal to one another. That is, the arms of the L or T each have a lengthwise or longitudinal axis, and two of these longitudinal axes are oriented at approximately 90.degree. with respect to one another. Each leg also has at least two shear strain gages mounted on orthogonal arms to measure forces in orthogonal directions. Three or more of these L or T shaped legs are integrated in a generally cylindrical and hollow body defining the force sensor. The shear strain gage outputs from the arms of this structure are sent to a digital signal processor which determines the magnitude and direction of any force/moment applied to the cylindrical body. Further, the shear strain gages are mounted in pockets sized to hold the strain gages and provide increased sensitivity to shear strain.
