Abstract
A fingerpad force sensor system is disclosed which is useful for detecting process variations during manufacturing processes in which a plurality of force sensors are applied to the gripper of a robot in order to monitor shear forces applied to the workpiece held by the robot during, for example, sheet-metal bending manufacturing processes. Each sensor is encapsulated in rubber pads which are secured to the gripper of the robot such that they monitor the status of the workpiece during all phases of automated bending: material acquisition, material handling, machine loading and unloading.
