Mobile Robot Safety Projection for Dynamic Travel Area Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile robots lack the ability to effectively project visual information for safety areas, failing to address changing conditions and ensuring travel safety, particularly in situations where obstacles or communication with other robots is unstable.
Innovation Solution
A mobile robot equipped with a projector that projects visual information to mark safety areas, adjusting the projection based on travel state and surrounding conditions, including changes in speed, direction, obstacles, and connected loads, without requiring direct communication with other robots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a projector is mounted on the mobile robot to provide visual information, then safety area marking capability is improved, but device complexity increases
Solution Approach 1:
The projector is integrated into the mobile robot to serve multiple functions: displaying entertainment content and marking safety areas. This multi-functionality approach allows the robot to enhance safety capabilities without adding separate dedicated safety marking devices, thereby improving reliability while controlling device complexity.
2Ease of operation
If the projector displays fixed safety guide information, then ease of operation is improved, but adaptability to changing conditions deteriorates
Solution Approach 1:
The projector dynamically adjusts the displayed safety area markings based on real-time sensor data about obstacles, robot velocity, and environmental conditions. The safety guide information is not fixed but adapts continuously to changing conditions, resolving the contradiction between ease of operation and adaptability by making the display both simple to understand and responsive to dynamic environments.
Solution Approach 2:
The system uses sensor feedback from obstacle detection devices and velocity sensors to continuously update the projected safety area markings. This feedback mechanism ensures the safety guide remains accurate and adaptable to current conditions while maintaining clear visual guidance for operators.
3Adaptability or versatility
If the safety area marking is updated in real-time based on sensor data, then adaptability to changing conditions is improved, but use of energy increases
Solution Approach 1:
The projector updates safety area markings at periodic intervals based on changes in sensor data rather than continuously. The system monitors obstacle detection and velocity data, triggering projector updates only when significant changes occur, thereby reducing energy consumption while maintaining real-time adaptability to critical safety conditions.

AI summary
A mobile robot can include a projector configured to project visual information onto one or more surfaces, and a controller configured to project, via the projector, first visual information for marking a safety area onto a ground surface in a vicinity of the mobile robot while the mobile robot is traveling, and in response to determining a change in at least one of a traveling state of the mobile robot or a surrounding situation of the mobile robot, generate changed first visual information and project the changed first visual information onto the ground surface.
