Abstract

A method, computer system, and a computer program product for payload stabilization is provided. The present invention may include, in response to receiving at least one sensor data associated with a suspended payload, detecting an unstable movement in the suspended payload during a transport of the suspended payload. The present invention may also include implementing at least one sail coupled to the suspended payload to stabilize the detected unstable movement of the suspended payload.

First claim

What is claimed is:

1. A computer-implemented method comprising:
in response to receiving at least one sensor data associated with a suspended payload, detecting an unstable movement in the suspended payload during a transport of the suspended payload; and
implementing at least one sail coupled to the suspended payload to stabilize the detected unstable movement of the suspended payload.

2. The method of claim 1 , wherein the at least one sensor data associated with the suspended payload is selected from the group consisting of a first set of movement data from at least one platform sensor, a second set of weather data from at least one external weather sensor, and a third set of imaging data from at least one image sensor.

3. The method of claim 2 , further comprising:
tracking, based on the first set of movement data from the at least one platform sensor, a position and orientation of a platform supporting the suspended payload during the transport of the suspended payload, wherein the at least one platform sensor is selected from the group consisting of a tilt sensor, a rotation sensor, an accelerometer, a gyroscope, and a wind sensor.

4. The method of claim 2 , further comprising:
determining, based on the second set of weather data from the at least one external weather sensor, a wind speed and a wind direction in a work environment.

5. The method of claim 2 , further comprising:
generating, based on the third set of imaging data from the at least one image sensor, at least one three-dimensional (3D) model of a work environment, wherein the generated at least one 3D model of the work environment is selected from the group consisting of a building model representing at least one building in proximity of the suspended payload during the transport of the suspended payload and a payload model representing the suspended payload located on a platform during the transport of the suspended payload.

6. The method of claim 2 , further comprising:
calculating, based on the at least one sensor data associated with the suspended payload, a predetermined movement of the suspended payload associated with the transport of the suspended payload.

7. The method of claim 2 , wherein detecting the unstable movement in the suspended payload further comprises:
detecting, based on the first set of movement data from the at least one platform sensor and the second set of weather data from the at least one external weather sensor, at least one external force acting on the suspended payload.

8. The method of claim 7 , wherein implementing the at least one sail coupled to the suspended payload to stabilize the detected unstable movement of the suspended payload further comprises:
determining, based on the first set of movement data from the at least one platform sensor, the second set of weather data from the at least one external weather sensor, and the third set of image data from the at least one image sensor, a controlled implementation of the at least one sail to counteract the at least one external force acting on the suspended payload.

9. The method of claim 1 , wherein the at least one sail coupled to the suspended payload is selected from the group consisting of a fabric sail and a rotary sail.

10. A computer system for payload stabilization, comprising:
one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage media, and program instructions stored on at least one of the one or more computer-readable tangible storage media for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
in response to receiving at least one sensor data associated with a suspended payload, detecting an unstable movement in the suspended payload during a transport of the suspended payload; and
implementing at least one sail coupled to the suspended payload to stabilize the detected unstable movement of the suspended payload.

11. The computer system of claim 10 , wherein the at least one sensor data associated with the suspended payload is selected from the group consisting of a first set of movement data from at least one platform sensor, a second set of weather data from at least one external weather sensor, and a third set of imaging data from at least one image sensor.

12. The computer system of claim 11 , further comprising:
tracking, based on the first set of movement data from the at least one platform sensor, a position and orientation of a platform supporting the suspended payload during the transport of the suspended payload, wherein the at least one platform sensor is selected from the group consisting of a tilt sensor, a rotation sensor, an accelerometer, a gyroscope, and a wind sensor.

13. The computer system of claim 11 , further comprising:
determining, based on the second set of weather data from the at least one external weather sensor, a wind speed and a wind direction in a work environment.

14. The computer system of claim 11 , further comprising:
generating, based on the third set of imaging data from the at least one image sensor, at least one three-dimensional (3D) model of a work environment, wherein the generated at least one 3D model of the work environment is selected from the group consisting of a building model representing at least one building in proximity of the suspended payload during the transport of the suspended payload and a payload model representing the suspended payload located on a platform during the transport of the suspended payload.

15. The computer system of claim 11 , further comprising:
calculating, based on the at least one sensor data associated with the suspended payload, a predetermined movement of the suspended payload associated with the transport of the suspended payload.

16. The computer system of claim 11 , wherein detecting the unstable movement in the suspended payload further comprises:
detecting, based on the first set of movement data from the at least one platform sensor and the second set of weather data from the at least one external weather sensor, at least one external force acting on the suspended payload.

17. The computer system of claim 16 , wherein implementing the at least one sail coupled to the suspended payload to stabilize the detected unstable movement of the suspended payload further comprises:
determining, based on the first set of movement data from the at least one platform sensor, the second set of weather data from the at least one external weather sensor, and the third set of image data from the at least one image sensor, a controlled implementation of the at least one sail to counteract the at least one external force acting on the suspended payload.

18. The computer system of claim 10 , wherein the at least one sail coupled to the suspended payload is selected from the group consisting of a fabric sail and a rotary sail.

19. A computer program product for payload stabilization, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
in response to receiving at least one sensor data associated with a suspended payload, detect an unstable movement in the suspended payload during a transport of the suspended payload; and
implement at least one sail coupled to the suspended payload to stabilize the detected unstable movement of the suspended payload.
