Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spherical household robots experience unstable motion and difficulty in maintaining a specific visual angle due to the camera's rotation with the rolling motion, leading to aberrant vision angles and poor image stability.
Innovation Solution
A gravity center adjustment mechanism comprising a circuit board with an angle detecting unit and a weight component, connected via an adjusting module, which dynamically adjusts the camera's gravity center to maintain a stable visual angle by detecting inclined angles and adjusting the weight component's position, utilizing a pendulum and counterweight system to balance the camera device.

Engineering Contradiction Analysis
1Speed
If the camera is simultaneously rotated with rolling of the spherical housing, then the spherical robot can move rapidly on the ground, but the camera cannot keep at the specific predetermined vision angle and the vision angle becomes unstable
Solution Approach 1:
The patent introduces a counterweight component that can be adjusted to compensate for the weight distribution changes during rolling motion. By dynamically adjusting the counterweight position, the system offsets the gravitational torque that causes camera angle instability, allowing the camera to maintain a predetermined vision angle even while the spherical robot moves rapidly.
Solution Approach 2:
The patent implements a dynamic adjustment mechanism that actively modifies the counterweight position based on real-time detection of the camera's orientation and the robot's rolling state. This dynamic compensation system continuously adapts to changing motion conditions, maintaining vision angle stability throughout the rolling motion rather than relying on fixed mechanical constraints.
2Device complexity
If the camera is fixed on the rolling spherical housing, then the structure is simple, but the camera experiences violent reversal and cannot maintain stable image capture
Solution Approach 1:
The patent adds a counterweight adjustment mechanism that compensates for the instability caused by fixed mounting during rolling. The counterweight system creates balancing torque to counteract the gravitational effects that cause violent camera reversal, thereby maintaining image capture reliability without requiring complete structural redesign.
Solution Approach 2:
The patent incorporates sensors that detect the camera's orientation and position during rolling motion, feeding this information back to a control system. The control system then adjusts the counterweight position in real-time based on the detected deviations, creating a closed-loop feedback system that maintains stable image capture despite the dynamic rolling environment.
