Binary Image Coding Algorithm Using Tactile Data Information

This paper describes the formulation and design principles of operation of a pneumatic proximity-to-tactile sensing device for automated recognition of objects within flexible manufacturing environments. This sensing device utilises a densely packed line array of piezoresistive pressure sensors, providing continuous variable output. The sensing head or plane of the device incorporates a corresponding line array of air jets which form boundary layers or air cushion when striking a target of interest. The back pressure data information obtained from the proposed tactile sensing device form the basis for the tasks of object detection and recognition. Therefore the device can be used to provide sensory information from a proximate location to object as well as when it is in contact with the same object. The proximity data corresponds to intrinsic information as object profile and local dimensions being monitored. The device is also capable to detect and monitor the amount of slip generated by the object of interest.
