Remote Robot Switching with Continuous Movement Transition

Solution Overview

Problem

Existing remote operation systems cause discomfort to operators when switching between robots due to deviations in movement or speed, disrupting the continuous movement experience.

Innovation Solution

An operation system that switches the operation target from a first moving object to a second moving object based on movement information, such as after the second object starts moving, the first object starts moving, or a video is adjusted according to the first object's movement, ensuring a seamless transition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operation terminal temporarily terminates the video from the switching source robot to transition to the robot selection screen, then the operator can select another robot, but the continuous movement experience is interrupted causing discomfort

Engineering Contradiction:

Improverobot switching operationVSAvoidcontinuous movement experience

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary actions by having the switching destination robot start moving based on the switching source robot's movement information before the actual switching occurs. This preliminary movement preparation ensures that when switching happens, the destination robot is already in motion, maintaining the operator's sense of continuous movement and reducing discomfort during the transition.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses an intermediary approach by displaying adjusted video content that bridges the gap between switching source and switching destination. The video adjustment uses the switching source robot's movement information to create a seamless visual transition, acting as an intermediary that maintains the continuous movement experience while enabling robot switching.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Speed

If the operation terminal switches the operation target immediately upon receiving a switching request, then the switching speed is fast, but the deviation in movement or speed between robots causes uncomfortable feeling

Engineering Contradiction:

Improveswitching speedVSAvoidoperator comfort

Core Design Contradiction:

SpeedVSEase of operation

Solution Approach 1:

The system performs preliminary actions by having the switching destination robot start moving based on the switching source robot's movement information before the actual switching occurs. This preliminary movement preparation ensures that when switching happens, the destination robot is already in motion, maintaining the operator's sense of continuous movement and reducing discomfort during the transition.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies parameter changes by adjusting the video content parameters based on the switching source robot's movement information. The video adjustment modifies playback speed, position, or other parameters to match the movement characteristics, creating a smooth transition that maintains operator comfort while enabling fast switching.

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If the video is displayed without adjustment during switching, then the display process is simple, but the deviation in movement creates discontinuous movement experience

AI summary

The operation system controls a moving object selected from a plurality of moving objects. The operation system includes a display unit that displays display information including an image of the surroundings of the moving body, and a switching unit that switches the control target from the first moving body to the second moving body by using the operation information indicating the operation of the moving body. The switching unit switches the control target from the first moving body to the second moving body in at least one of a case where the second moving body starts the operation based on the operation information of the first moving body, a case where the first moving body starts the operation based on the operation information of the second moving body, and a case where the display unit displays an image adjusted in accordance with the operation information of the first moving body.
