Robot Suspension Damping Control for Shock Absorption and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot technologies struggle to balance shock absorption performance and stability, as setting low suspension stiffness improves shock absorption but compromises stability, while high stiffness sacrifices shock absorption.
Innovation Solution
A robot design incorporating a controllable damping rotating shaft and suspension shock absorber that work together to provide an opposing force to the robot's swing direction, ensuring stability even with low suspension stiffness, and a controller adjusts rotational resistance based on pose information from a detector.

Engineering Contradiction Analysis
1Object-affected harmful factors
If suspension stiffness is reduced to improve shock absorption performance, then shock absorption performance is improved, but robot body stability deteriorates
Solution Approach 1:
The patent combines the suspension shock absorber and controllable damping rotating shaft into a unified shock absorption and stabilization system. The suspension shock absorber handles vertical vibrations while the rotating shaft counteracts body swinging, creating a coordinated dual-mechanism system that resolves the contradiction between shock absorption and stability.
Solution Approach 2:
The controllable damping rotating shaft dynamically adjusts its rotational resistance based on real-time pose detection feedback. The controller modulates the damping coefficient according to the robot's current state, enabling adaptive stabilization that maintains stability even with reduced suspension stiffness.
2Stability of the object's composition
If active stabilization methods are used to maintain robot stability, then robot body stability is improved, but energy consumption increases
Solution Approach 1:
The controllable damping rotating shaft utilizes the robot's own motion and pose information to generate stabilizing forces. By detecting pose deviations and automatically adjusting rotational resistance, the system achieves self-stabilization without requiring additional active actuators or energy-intensive control mechanisms.
Solution Approach 2:
The patent replaces traditional active stabilization mechanisms (such as active suspension actuators or stabilization motors) with a passive controllable damping system. The damping rotating shaft uses controlled rotational resistance rather than active force generation, significantly reducing energy consumption while maintaining stability.
