Abstract
The present disclosure is applicable to robot technology. A method, an apparatus and a terminal device for robot fall prediction are provided. The method includes: searching for a gravity center offset weighting value corresponding to a posture of a robot; correcting a gravity center offset of the robot basing on the gravity center offset weighting value; correcting an acceleration of the robot basing on a gravity center offset direction of the robot; and determining whether the robot will fall or not basing on the corrected gravity center offset and the corrected acceleration. The present disclosure improves the real-time performance and accuracy of the prediction for the fall of a robot through the fusion calculation of various data.
Claims17
A computer-implemented method for robot fall prediction, comprising executing on a processor the steps of:
- searching for a gravity center offset weighting value corresponding to a posture of a robot;
- correcting a gravity center offset of the robot basing on the gravity center offset weighting value;
- correcting an acceleration of the robot basing on a gravity center offset direction of the robot;
- and
- determining whether the robot will fall or not basing on the corrected gravity center offset and the corrected acceleration.
An apparatus for robot fall prediction comprising a processor and a memory storing instructions executable for the processor, wherein the instructions functions as:
- a search module configured to search a gravity center offset weighting value corresponding to a posture of a robot;
- a gravity center offset correction module configured to correct a gravity center offset of the robot basing on the gravity center offset weighting value;
- an acceleration correction module configured to correct an acceleration of the robot basing on a gravity center offset direction of the robot;
- and
- a determination module configured to determine whether the robot will fall or not basing on the corrected gravity center offset and the corrected acceleration.
A terminal device comprising a processor and a memory storing a computer program executable for the processor, wherein the processor is configured to execute the computer program to implement the steps of:
- searching for a gravity center offset weighting value corresponding to a posture of a robot;
- correcting a gravity center offset of the robot basing on the gravity center offset weighting value;
- correcting an acceleration of the robot basing on a gravity center offset direction of the robot;
- and
- determining whether the robot will fall or not basing on the corrected gravity center offset and the corrected acceleration.
