Application: Control device, unmanned aerial vehicle, and control method (Patent ID: US20240043118A1)
The patent filed by Rakuten Group Inc. describes a control device for an unmanned aerial vehicle (UAV) that includes a winch, an attachment member, and a linear member. The control device is designed to acquire distance information indicating the distance between the UAV and an article positioned underneath it, and then control the winch to unreel the linear member based on this distance information. The device includes program code stored in memory that allows the processor to acquire the distance information and determine the unreeling length of the linear member, as well as generate reaction forces for reeling the linear member when necessary. The control method executed by the computer involves acquiring distance information and controlling the winch to unreel the linear member accordingly.
Overall, the patent focuses on a sophisticated control system for UAVs that enables precise and automated control of the winch and linear member based on the distance between the UAV and the target article. The system includes features such as acquiring distance information in a time series, generating reaction forces for reeling the linear member, locking the unreeling when necessary, and controlling the winch based on vertical positions. The technology described in the patent aims to enhance the efficiency and accuracy of UAV operations, particularly in scenarios where the UAV needs to interact with objects on the ground.
