Experimental analysis on a 4 leg-type force-torque sensor

This paper presents an experimental analysis on a new force-torque sensor with a 4 leg-type elastic structure. Cross coupling effect in the sensor is minimized using compliance matrix. The positions of strain gauges in the elastic structure are determined using surface strain distribution of the elastic structure via FEM analysis. For user convenience, USB communication between the sensor body and the control PC is realized through C and Visual Basic programming using PIC microcontrollers.
