Decoupled Nose and Velocity Control for Motion-Sensing Drones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motion-sensing remote controllers for movable platforms, such as aircraft, provide low degrees of freedom in control due to the movement direction always changing with the nose direction, limiting user interaction and camera movement styles.
Innovation Solution
A control method and apparatus that allows for an angle greater than 0° to be formed between the nose direction and the horizontal component of the velocity vector of the movable platform by receiving multiple operations on a motion-sensing controller, including joystick and trigger inputs, enabling decoupled control of the nose direction and velocity vector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motion-sensing control is used to control the movable platform, then the ease of operation is improved, but the degree of freedom of control deteriorates because the movement direction always changes according to the nose direction
Solution Approach 1:
The control system is segmented into independent control channels: one for nose direction control and another for velocity vector control. This allows the user to independently adjust the nose direction and the movement direction, breaking the coupled relationship in traditional motion-sensing control and enabling greater control freedom.
Solution Approach 2:
The control system adds a new dimension of control by introducing independent velocity vector control alongside nose direction control. This transforms the control from a single-axis motion-sensing approach to a multi-dimensional control system where nose direction and movement direction can be independently adjusted, increasing the degree of freedom.
2Adaptability or versatility
If multiple operations are received from the motion-sensing controller, then the degree of freedom of control is improved, but the device complexity increases
Solution Approach 1:
The motion-sensing controller is designed with multi-functionality, where a single device can perform both nose direction control and velocity vector control through different operation modes. This eliminates the need for separate control devices and maintains simplicity while achieving enhanced control freedom.
Solution Approach 2:
The control system dynamically switches between different control modes based on the operations received. The controller can adaptively adjust the control parameters and control laws in real-time, allowing flexible implementation of multiple control functions without requiring a complex fixed architecture.

AI summary
A control method and apparatus for a movable platform, a movable platform and a storage medium are provided. The method comprises: receiving a first operation and a second operation input by a user, where the first operation and the second operation are operations on different objects of a motion-sensing controller, and one of the first operation and the second operation is a motion-sensing control operation of the motion-sensing controller; and in response to the first operation and the second operation, generating a control instruction, where the control instruction is used to control the movable platform, and the control instruction causes an angle greater than 0° to be formed between a nose direction of the movable platform and a horizontal component direction of a movement velocity of the movable platform.
