Title:
METHOD AND APPARATUS FOR ROBOT COLLISION AVOIDANCE BY FULL SURFACE PROXIMITY DETECTION
Document Type and Number:
WIPO Patent Application WO/2022/186532
Kind Code:
A1
Abstract:
An apparatus includes a plurality of piezoelectric elements, a memory storing instructions, and at least one processor configured to execute the instructions to control a first one among the piezoelectric elements to generate an acoustic wave along a surface of an object, receive, via a second one among the piezoelectric elements, an acoustic wave signal corresponding to the generated acoustic wave, filter the received acoustic wave signal, using a band-pass filter for reducing noise of the received acoustic wave signal, obtain a proximity signal for proximity detection, from the filtered acoustic wave signal, by using a linear time-invariant filter, predict whether an obstacle is within a first distance from the surface of the object by inputting the obtained proximity signal to a neural network. and control the object to avoid collision with the obstacle, based on the obstacle being within the first distance from the surface of the object.
