Mobile Robot Route Adjustment Through Touch Points on Camera View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile robot control systems are inconvenient for users as they restrict the ability to freely change planned routes, limiting user interaction and flexibility in route adjustments.
Innovation Solution
A control method using a terminal apparatus with a camera and display, allowing users to easily modify planned routes by detecting contact points on the screen and transmitting these changes to the mobile robot's control circuit, enabling real-time route adjustments and intuitive route changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile robot uses a predetermined response range for route changes, then the system maintains control reliability, but the user cannot freely change the direction of the planned route
Solution Approach 1:
The patent transitions from a one-dimensional constraint (predetermined response range) to a two-dimensional solution by overlaying the planned route visually on the display screen. This allows users to interact with any point on the displayed route, effectively adding a spatial dimension to route modification capabilities while maintaining system control through coordinate-based instructions.
Solution Approach 2:
The display screen acts as an intermediary between the user and the mobile robot's route control system. By displaying the planned route and detecting touch coordinates on the screen, the system mediates user intent into precise directional changes without requiring complex control algorithms or sacrificing reliability.
2Ease of operation
If the system displays only the planned route without visual reference, then the control system remains simple, but the user cannot easily grasp or modify the route
Solution Approach 1:
The patent merges the camera image and the planned route into a single composite display. This overlay technique combines visual reference (camera image) with route information in one view, enabling users to easily grasp and modify routes by touching the displayed image without requiring separate displays or complex interfaces.
Solution Approach 2:
The system creates a visual copy of the environment through the camera image and overlays the planned route on this copy. This allows users to interact with a digital representation rather than the physical robot directly, simplifying the interface while enhancing ease of operation.
3Adaptability or versatility
If the system requires complex processing to allow free route changes, then route flexibility improves, but the response time and processing load increase
Solution Approach 1:
The patent replaces complex mechanical control processing with a simplified coordinate-based system. By detecting touch coordinates on the display screen and converting them to directional instructions, the system achieves fast route modifications without requiring complex algorithms, thereby reducing processing time and improving response speed.

AI summary
A terminal apparatus includes a camera, a display that displays a display screen including a mobile robot that autonomously travels, and a control circuit. The control circuit acquires a first planned route of the mobile robot, displays, on the display, a screen having the first planned route superimposed on a camera image taken by the camera, detects a contact point on the display on which the screen is displayed, generates a second planned route of the mobile robot that travels through the contact point, and transmits the second planned route to the mobile robot.
