Robot Tip-Over Prevention Member for Stable Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots face challenges in relocation due to tip-over issues during movement, as the weight distribution and frictional forces are not effectively managed, leading to instability and difficulty in navigating surfaces.
Innovation Solution
The robot incorporates a base with a flat mounting surface and a movable unit, featuring a switchable tip-over prevention member that protrudes during relocation to enhance stability and a friction-reducing mechanism like wheels that ascend and descend to minimize friction, allowing for safe and efficient movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the robot uses casters and outrigger for relocation, then the robot can be moved horizontally, but the robot may tip over during the relocating process due to unstable weight distribution
Solution Approach 1:
The tip-over prevention member is designed to be switchable between protruding and retracted states. During relocation, it protrudes forward to extend the base and prevent tipping. During installation, it is retracted to avoid interfering with the mounting surface. This dynamic adjustment allows the system to adapt its stability characteristics based on operational requirements.
Solution Approach 2:
The tip-over prevention member is positioned to protrude forward in advance before the robot begins moving. This preliminary positioning ensures that the extended base is already in place to counteract tipping forces before they occur during the relocating process.
2Stability of the object's composition
If the tip-over prevention member protrudes forward during relocation, then tip-over is prevented, but the member may hinder the installation space when the robot is set on the installation surface
Solution Approach 1:
The tip-over prevention member transitions from a protruding state during relocation to a retracted state during installation. This dynamic switching ensures that the member provides tip-over prevention when needed while clearing the installation space when the robot is being set up or operated in its installed position.
Solution Approach 2:
The tip-over prevention member is extracted from the protruding position during installation operations. By retracting the member, it is removed from the installation space, eliminating any interference with the mounting surface or surrounding equipment during setup and normal operation.
3Ease of operation
If the base is raised by causing the outrigger to ascend, then the weight is supported by casters for movement, but friction increases making relocation difficult
Solution Approach 1:
The tip-over prevention member acts as an intermediary element that extends the base forward during relocation. This extension creates a more favorable weight distribution and reduces the frictional resistance at the caster contact points, making it easier to move the robot horizontally while maintaining stability.

AI summary
A robot including a base having a flat mounting surface section to be set on an installation surface by a fixing part, and also including a movable unit that is movable relative to the base. The base includes a tip-over prevention member that is disposed in a switchable manner between a state where the tip-over prevention member at least protrudes forward from the mounting surface section in a moving direction when a relocating process is performed and a state where the tip-over prevention member does not protrude forward from the mounting surface section.
