Security Robot Camera Stabilization With Cable-Safe Rotation

Solution Overview

Problem

Security robots experience unstable image capture due to changing orientations and uneven terrain, leading to shaky or blurred video, and existing cable configurations hinder smooth rotation of camera devices.

Innovation Solution

A security robot with an image stabilization function that includes a base plate, turn gear, turn housing, and turn plate with hollow portions for cables, along with a tilty motor and gyro sensor to adjust the camera's orientation and minimize cable resistance, allowing the camera to track targets despite the robot's changing orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cables are wired to electrical and electronic devices with thick sheath or highly durable material to prevent damage during rotation, then cable durability is improved, but resistance to rotation increases and smooth rotation is hindered

Engineering Contradiction:

Improvecable durabilityVSAvoidrotation smoothness

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts the cable from the rotational path by routing it through a cable guide that separates the cable's power transmission function from the rotational motion function. The cable is positioned in a cable guide groove that prevents it from being twisted or damaged during rotation, while using thinner, more flexible cable material that does not resist rotation.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The cable guide acts as an intermediary component between the cable and the rotating camera device. It provides a protective pathway that allows the cable to remain stationary or move minimally while the camera rotates freely, eliminating direct contact and friction between the cable and rotating components.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the security robot moves to navigate obstacles and reach destination, then mobility and adaptability are improved, but image stability deteriorates due to changing orientation and posture

Engineering Contradiction:

Improveobstacle navigation capabilityVSAvoidimage stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent segments the robot system into independent rotational modules: the base plate for overall movement, the turn housing for horizontal rotation, and the tilting mechanism for vertical adjustment. The image stabilization unit operates independently within this segmented structure, compensating for orientation changes caused by robot movement to maintain stable imaging.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The image stabilization function uses feedback from sensors to detect changes in robot orientation and posture, then adjusts the camera angle in real-time to compensate for these changes. This closed-loop control maintains image stability despite the robot's dynamic movement through uneven terrain and obstacles.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the camera device rotates to track moving targets, then target tracking capability is improved, but cable damage risk increases due to interference and friction

Engineering Contradiction:

Improvetarget tracking capabilityVSAvoidcable integrity
