Service Robot Rotating Display for User-Following Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing service robots lack dynamic display interaction capabilities, as their screens remain fixed and do not adapt to user proximity or movement, failing to provide an engaging anthropomorphic experience.
Innovation Solution
A service robot equipped with a human body recognition sensor to trigger device operation, distance sensors to determine user orientation and distance, and a camera for facial recognition, allowing the display screen to rotate and adjust angles to maintain focus on the user, enhancing interaction through anthropomorphic communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display screen remains fixed, then the device structure is simple, but the display interaction capability is poor and cannot adapt to user proximity or movement
Solution Approach 1:
The display screen is transformed from a fixed static structure to a dynamic adjustable structure that can rotate and tilt. The screen is mounted on a rotating mechanism that allows it to change orientation based on user position, enabling the display to adapt dynamically to different interaction scenarios while maintaining a relatively simple overall device structure.
Solution Approach 2:
A sensor system is introduced to detect user proximity and position, providing feedback signals to the control unit. The control unit processes this feedback and automatically adjusts the display screen orientation accordingly, creating a closed-loop adaptive interaction system that enhances display capability without requiring complex manual control mechanisms.
2Adaptability or versatility
If the display screen rotates to follow the user, then the anthropomorphic interaction is enhanced, but the device complexity increases due to additional sensors and control mechanisms
Solution Approach 1:
The sensor system serves multiple functions: it detects user proximity, determines user position, and triggers appropriate display responses. By making the sensor system multi-functional, the patent reduces the need for separate specialized sensors for each function, thereby limiting the increase in device complexity while achieving enhanced anthropomorphic interaction.
Solution Approach 2:
The system is designed to automatically detect user presence and adjust display orientation without requiring manual intervention. The control unit autonomously processes sensor data and commands the display mechanism, making the system self-regulating and reducing the need for complex external control interfaces.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables the service robot to interact more vividly with users by ensuring the display screen always faces and adjusts to the user, improving the overall user experience and anthropomorphic interaction.
Implementation Method 1
a human body recognition sensor configured to detect whether a user appears within a predetermined range around the service robot
Implementation Method 2
the distance sensor is configured to measure a distance between the user and the service robot after the operation is started
Implementation Method 3
the camera is configured to capture a camera view in the case where the controller receives the start signal; the controller is configured to recognize a face area in the camera view
Data Source
AI summary
Provided are a service robot and a display control method thereof, a controller and a storage medium. The service robot display control method comprises receiving a start signal sent by a human body recognition sensor, wherein the human body recognition sensor outputs the start signal to a controller in the case where a user appears within a predetermined range around the service robot, and controlling the mounted device to start operation in the case where the start signal is received. A first display screen of the robot is in a standby state when there is no user, and when a user approaches the robot, the first display screen starts to light up.
