Gimbal Balance Control Using Tilt Feedback and Slider Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting the balance of a gimbal apparatus are inefficient when center-of-gravity information of the mounted object is unavailable, leading to prolonged balance adjustment times.
Innovation Solution
A gimbal apparatus equipped with a slider, rotator, position detectors, and a processor that controls the slider and rotator based on detected position and rotation angle information to adjust the center of gravity, allowing for rapid balance adjustment without continuous power application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If center-of-gravity information of the mounted object is unavailable, then balance adjustment cannot be performed using prior art methods, but this results in prolonged balance adjustment time
Solution Approach 1:
The gimbal apparatus performs self-diagnosis by automatically detecting its own tilt angle using the tilt detector, and autonomously calculates the required slider movement to correct the imbalance. The system serves itself by using its own sensor data to identify and correct balance issues without requiring external center-of-gravity information from the mounted object
Solution Approach 2:
The system uses feedback from the tilt detector to continuously monitor the tilt angle of the mounted object, processes this information through the processor to determine the appropriate slider movement amount, and adjusts the slider position accordingly. This closed-loop feedback mechanism enables automatic balance adjustment without needing prior center-of-gravity data
2Stability of the object's composition
If slider position is adjusted frequently for balance adjustment, then center of gravity can be aligned, but continuous power application is required which increases energy consumption
Solution Approach 1:
The balance adjustment is performed as a preliminary action during system initialization or when imbalance is detected, rather than continuously. The slider is positioned correctly in advance to align the center of gravity, and once positioned, the system maintains this state without requiring continuous power application to the slider motor
Solution Approach 2:
Instead of continuous operation, the slider adjustment mechanism operates periodically or event-drivenly - specifically when balance adjustment is needed. The system transitions the slider to the appropriate position and then maintains it statically, reducing energy consumption by eliminating continuous power application while preserving center of gravity alignment

AI summary
A gimbal apparatus to which a mounted object is detachably attachable includes a slider translatable in a predetermined direction, a rotator rotatable around a predetermined axis, a slide position detector configured to detect position information on the slider, a rotation position detector configured to detect rotation angle information on the rotator, a memory storing instructions, a processor that, upon execution of the instructions, is configured to control the slider based on the position information and control the rotator based on the rotation angle information, a fixed unit configured to fix the mounted object, and a tilt detector configured to detect a tilt angle of the mounted object fixed to the fixed unit relative to a predetermined position. The processor is configured to determine a moving amount of the slider so as to reduce the tilt angle.
