Mobile Robot Stair Detection and Automatic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic systems require manual operator intervention to transition between operational modes for traversing stairs, which is inconvenient and potentially dangerous, especially if the operator fails to switch modes correctly.
Innovation Solution
A mobile robot equipped with sensors and a processor that automatically detects stairs and transitions into a specialized 'stairs mode' as it moves along a path, using decision trees and setting values to adjust settings for effective stair perception and traversal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operator intervention is used to transition between operational modes, then the operator can control the robot's behavior, but the operation becomes inconvenient and potentially dangerous
Solution Approach 1:
The robot automatically detects stairs using sensor data and transitions to stairs mode without operator intervention. The system monitors its own environment and autonomously adjusts its operational mode based on detected terrain conditions, eliminating the need for manual mode switching while maintaining safety.
Solution Approach 2:
The robot continuously receives feedback from sensors about the environment and uses this information to automatically transition between operational modes. The feedback loop enables the robot to detect stairs and respond by switching to the appropriate mode, ensuring safe operation without manual intervention.
2Adaptability or versatility
If the robot uses multiple operational modes for different terrains, then the robot can adapt to various environments, but the device complexity increases
Solution Approach 1:
The robot dynamically transitions between operational modes based on real-time sensor data and detected terrain conditions. Rather than requiring manual configuration or complex pre-programming, the system automatically adjusts its operational mode to match the current environment, maintaining versatility while simplifying operation.
Solution Approach 2:
The robot pre-configures multiple operational modes for different terrain types and automatically selects the appropriate mode based on sensor detection. This preliminary preparation of modes allows the robot to adapt to various terrains without increasing operational complexity during execution.
Data Source
AI summary
According to one disclosed method, one or more sensors of a robot may receive data corresponding to one or more locations of the robot along a path the robot is following within an environment on a first occasion. Based on the received data, a determination may be made that one or more stairs exist in a first region of the environment. Further, when the robot is at a position along the path the robot is following on the first occasion, a determination may be made that the robot is expected to enter the first region. The robot may be controlled to operate in a first operational mode associated with traversal of stairs when it is determined that one or more stairs exist in the first region and the robot is expected to enter the first region.
