Autonomous Robot Distance Control for Natural Human Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robot technologies, despite advancements, fail to replicate the warmth and companionship of living beings, as they are designed with fixed operational controls and lack the ability to autonomously adapt to internal states and external environments.
Innovation Solution
An autonomously acting robot equipped with a filming unit for periphery observation and a movement control unit that adjusts distance based on target object size, allowing it to compute and maintain optimal positional relationships, thereby simulating vitality and interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot operates with fixed control programs, then the robot's operational reliability is improved, but the robot's adaptability to internal states and external environments deteriorates
Solution Approach 1:
The patent implements dynamic control by allowing the robot to adjust its operations based on internal states (hunger, fatigue, comfort levels) and external environmental conditions. The control system transitions from fixed programs to dynamic decision-making that adapts to changing conditions, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The robot incorporates feedback mechanisms through sensors that continuously monitor internal states and external environments. This feedback loop enables the robot to adjust its behavior in real-time, maintaining operational reliability while adapting to changing conditions, thus resolving the technical contradiction.
2Device complexity
If the robot maintains a fixed distance from target objects, then the robot's operational simplicity is improved, but the robot's ability to provide natural interaction deteriorates
Solution Approach 1:
The robot dynamically adjusts its distance from target objects based on object size and interaction context. Rather than maintaining a fixed distance, the robot modulates its position to provide natural-looking interactions, resolving the contradiction between operational simplicity and interaction quality.
Solution Approach 2:
The robot changes operational parameters (distance, position) based on target object characteristics. By adjusting the distance parameter according to object size and type, the robot achieves natural interaction without requiring complex operational procedures, thus resolving the technical contradiction.

AI summary
A robot includes a filming unit that films a periphery, and a movement control unit that controls a distance from a filmed target object in accordance with a size of the target object. The robot may further include an operation control unit that controls an operation of a head portion, and a recognizing unit that recognizes a face of the filmed target object. The operation control unit may control the operation of the head portion so that a line of sight of the head portion reaches an angle of looking up directed at the face of the target object. The movement control unit may control the distance from the target object in accordance with a height of the target object.
