Remote Steering Display for Communication-Lagged Mobile Body Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote piloting systems, communication lag between the pilot seat and the mobile body leads to a lapse between steering timing by the operator and the actual mobile body, causing instability due to unnecessary adjustments.
Innovation Solution
A remote operating device with a steering unit, display unit, and control unit that receives and displays actual steering information, allowing operators to accurately ascertain the mobile body's movement by comparing predicted and actual trajectory lines, and adjusting the display format based on overlap thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote piloting is implemented with external pilot seat, then operator can control mobile body from distance, but communication lag causes lapse between steering timing in pilot seat and actual mobile body
Solution Approach 1:
The system displays actual steering information from the mobile body alongside steering information for the steering unit, creating a feedback loop that shows the operator the real-time relationship between their steering inputs and the actual mobile body movement, compensating for communication lag
Solution Approach 2:
The display unit acts as an intermediary between the steering unit and the mobile body, visually mediating the relationship by showing both the steering commands issued and the actual movement received, bridging the information gap caused by communication delay
2Device complexity
If steering information is displayed without visual comparison, then display is simple, but operator cannot accurately ascertain relationship between steering input and mobile body movement
Solution Approach 1:
The system adds a visual dimension to steering information by displaying trajectory lines that show the relationship between steering input and mobile body movement, transforming abstract timing data into intuitive spatial visual representation
3Loss of information
If trajectory lines overlap heavily, then visual comparison becomes difficult, but displaying all information simultaneously provides complete data
Solution Approach 1:
The system applies different visual properties (line types, colors, patterns) to different trajectory lines in the same display space, allowing complete information to be presented while maintaining visual distinction through local quality variations

AI summary
A remote operating device including a steering unit configured to steer a mobile body, a display unit configured to display steering information, and a control unit. The control unit includes a memory and a processor coupled to the memory. The processor is configured to receive actual steering information regarding the mobile body, acquire steering information for steering the steering unit, determine a difference between the actual steering information regarding the mobile body and the steering information for steering the steering unit, and cause the steering information for steering the steering unit and the actual steering information regarding the mobile body to be displayed on the display unit based on the difference.
