==METHOD AND APPARATUS FOR ESTIMATING TOUCH LOCATIONS AND TOUCH PRESSURES - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17553321 titled 'METHOD AND APPARATUS FOR ESTIMATING TOUCH LOCATIONS AND TOUCH PRESSURES

==Simplified Explanation==

The abstract describes a tactile sensing system for a robot that uses piezoelectric elements to detect touch input on an object's surface. The system includes a transmitter (TX) piezoelectric element and a receiver (RX) piezoelectric element. 

* The TX piezoelectric element generates an acoustic wave with a chirp spread spectrum (CSS) at regular intervals along the object's surface.
* The RX piezoelectric element receives the acoustic wave signal corresponding to the generated wave.
* The system selects frequency bands from the received acoustic wave signal.
* A neural network is used to analyze the selected frequency bands and estimate the location of the touch input on the object's surface.

Potential applications of this technology:

* Robotic systems that require precise touch sensing capabilities.
* Human-robot interaction scenarios where robots need to respond to touch input.
* Industrial automation processes that involve delicate handling of objects.

Problems solved by this technology:

* Provides a reliable and accurate method for robots to detect touch input on objects.
* Enables robots to interact with their environment more effectively.
* Improves the ability of robots to perform tasks that require tactile sensing.

Benefits of this technology:

* Enhanced robot capabilities in various industries, such as manufacturing, healthcare, and entertainment.
* Improved safety in human-robot interaction scenarios.
* Increased efficiency and accuracy in robotic tasks that involve touch sensing.


==Original Abstract Submitted==

A tactile sensing system of a robot may include: a plurality of piezoelectric elements disposed at an object, and including a transmission (TX) piezoelectric element and a reception (RX) piezoelectric element; and at least one processor configured to: control the TX piezoelectric element to generate an acoustic wave having a chirp spread spectrum (CSS) at every preset time interval, along a surface of the object; receive, via the RX piezoelectric element, an acoustic wave signal corresponding to the generated acoustic wave; select frequency bands from a plurality of frequency bands of the acoustic wave signal; and estimate a location of a touch input on the surface of the object by inputting the acoustic wave signal of the selected frequency bands into a neural network configured to provide a touch prediction score for each of a plurality of predetermined locations on the surface of the object.
