Solution Overview

Problem

Current tele-presence robots lack full visibility and control, leading to potential collisions and safety issues when navigating between destinations, and existing tele-manipulator robots are heavy and not portable, limiting their versatility and operational efficiency.

Innovation Solution

A mobile robotic manipulator with a telepresence system featuring a chassis assembly with omni drive wheels, a tilting arm assembly, and a rotary gripper assembly, equipped with anti-toppling arms and a door locking mechanism, allowing for flexible movement and precise control in various environments, including door handling and conferencing scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If tele-manipulator robots are designed with heavy structures for stability and manipulation capability, then manipulation precision and stability are improved, but portability and ease of movement deteriorate

Engineering Contradiction:
Improverobot stabilityVSAvoidrobot weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The patent implements anti-toppling arms that can dynamically extend and retract based on operational needs. During manipulation tasks, the arms extend to provide stability support. During movement, they retract to minimize weight and drag. This dynamic adjustment resolves the contradiction between needing heavy structures for stability and requiring light structures for portability.

Inventive Principle:
Principle #15Dynamics

2Weight of moving object

If tele-presence robots are designed to be lightweight and portable, then ease of movement and portability are improved, but stability and collision avoidance capability deteriorate

Engineering Contradiction:
Improverobot weightVSAvoidcollision avoidance reliability
Core Design Contradiction:
Weight of moving objectVSReliability

Solution Approach 1:

The patent incorporates anti-toppling arms that act as preliminary protective structures. Before a collision can occur, these arms are positioned to prevent toppling. The arms serve as a first line of defense that actively counteracts potential instability events, allowing the robot to maintain lightweight construction while improving reliability.

Inventive Principle:
Principle #9Preliminary anti-action

3Adaptability or versatility

If omni drive wheels are used to enable movement in all directions, then navigation flexibility and adaptability are improved, but device complexity and control difficulty increase

Engineering Contradiction:
Improvenavigation flexibilityVSAvoiddrive system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs omni-directional wheels that can function in multiple modes: they can roll forward and backward, move laterally, and rotate in place. This multi-functionality allows a single wheel design to replace what would otherwise require multiple specialized wheels or complex mechanical steering mechanisms, achieving navigation flexibility without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
