Robot Elevator Boarding Control with Passenger-Aware Car Screening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots face challenges in navigating elevators safely and efficiently, often colliding with passengers or interfering with their operations, leading to discomfort and security risks.
Innovation Solution
A method and system for controlling robots to take elevators by receiving requests, acquiring passenger information, and determining if elevator cars meet pre-set conditions before allowing entry, prioritizing passenger operations, and using sensors to avoid conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If robots navigate elevators autonomously using radar-based navigation, then robots can take elevators independently, but collision and conflict with passengers may occur
Solution Approach 1:
The patent combines multiple sensing technologies (radar, cameras, depth sensors, ultrasonic sensors) into an integrated sensing system that merges data from different sources to achieve both autonomous operation and reliable collision avoidance through multi-modal perception
Solution Approach 2:
The elevator control system acts as an intermediary between robots and passengers, managing robot access through virtual queues, priority-based scheduling, and coordinated door control to prevent conflicts while maintaining autonomous robot operation
2Adaptability or versatility
If robots are allowed to take elevators freely, then elevator service coverage is expanded, but passenger comfort and security may be compromised
Solution Approach 1:
The system performs preliminary actions by pre-assessing elevator car conditions (weight, capacity, passenger presence) before allowing robot entry, and by establishing virtual queues and priority levels in advance to prevent conflicts and ensure passenger comfort
Solution Approach 2:
The patent implements dynamic control mechanisms where robot access rights are adjusted in real-time based on elevator load conditions, passenger presence, and priority levels, allowing flexible adaptation between expanding service coverage and ensuring passenger safety
3Measurement precision
If multiple sensors are used to detect passenger information, then collision detection accuracy is improved, but system complexity increases
Solution Approach 1:
The sensing system is segmented into specialized modules (radar for distance, cameras for visual identification, depth sensors for spatial mapping, ultrasonic sensors for proximity detection), where each sensor type handles specific detection tasks to improve overall accuracy while managing complexity through functional division

AI summary
A method for controlling a robot to take elevator, a system for controlling a robot to take elevator, an elevator system, a robot system, and a computer-readable storage medium. The method for controlling a robot to take elevator includes receiving an elevator-taking request from a robot; acquiring current passenger information in at least one elevator car; and determining whether the elevator car meets a pre-set carrying condition according to the acquired current passenger information: if yes, instructing the robot to board the elevator car in response to the elevator-taking request; otherwise, rejecting the elevator-taking request.
