Vehicle Simulator Motion Feedback for Unmanned Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned vehicle operators lack tactile feedback and a sense of physical motion, leading to reduced situational awareness and control effectiveness compared to manned vehicle pilots.
Innovation Solution
A mobile and versatile vehicle simulator is integrated with a vehicle control system to provide motion feedback in multiple axes, simulating turbulence, bumps, and other vehicle motions based on actual vehicle conditions, allowing operators to feel the orientation and motion of the vehicle without visual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a control interface similar to video games is used, then ease of operation is improved, but tactile feedback and sense of physical motion are lost
Solution Approach 1:
A motion simulator platform acts as an intermediary device between the operator and the unmanned vehicle. The simulator receives motion data from the vehicle and reproduces it as physical movements of the operator's seat, providing tactile feedback without interfering with the simple video game-style control interface.
Solution Approach 2:
The control system is segmented into separate functional components: the video game-style control interface for ease of operation, the motion simulator for tactile feedback, and the feedback processing system. This allows each component to optimize its specific function without compromising the others.
2Device complexity
If visual and audio input only is provided, then device complexity is reduced, but situational awareness is diminished
Solution Approach 1:
The information feedback system is segmented into multiple channels: visual display, audio feedback, and tactile motion feedback. Each channel provides different types of situational information, creating a comprehensive awareness system without requiring a single complex interface.
Solution Approach 2:
The motion simulator serves multiple functions simultaneously: it provides tactile feedback about vehicle motion, enhances situational awareness through physical sensation, and maintains operator comfort by using realistic motion patterns that match actual flight conditions.
3Loss of information
If motion feedback is provided to simulate actual vehicle motion, then sense of presence is improved, but operator disorientation may occur
Solution Approach 1:
The system uses feedback from the actual vehicle motion data to control the simulator's movements. By accurately reproducing only the real motion experienced by the vehicle, the simulator maintains a realistic sense of presence without creating artificial or disorienting motion patterns.
Solution Approach 2:
The motion simulator provides partial motion feedback by reproducing only the relevant vehicle motions that contribute to situational awareness, while filtering out excessive or redundant movements that could cause operator disorientation.

AI summary
A mobile and versatile vehicle simulator is integrated with a vehicle control system to provide a mobile simulator based vehicle control system such as the exemplary system. The vehicle simulators included in the simulator based control system allows for a vehicle operator to be moved in two or even three axis of rotation while, in some embodiments, also allowing for sudden jolts or motion similar to what might be encountered when a pilot encounters air turbulence or a driver encounters ruts or pot holes.
