Work Machine Remote Operation Alerts for Operator Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of a work machine may experience unexpected activation due to simultaneous on-board and remote operations, leading to misunderstandings and panic, as both operators may not be aware of the other's actions.
Innovation Solution
A work machine and remote operation support system that includes an actuator, operator's seat, operation device, processing circuitry, and output device to notify operators of remote operation status, ensuring awareness and coordination between on-board and remote operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the work machine allows both onboard operator control and remote operation, then operational flexibility and versatility are improved, but the risk of unexpected activation and operator confusion increases
Solution Approach 1:
The system implements feedback by notifying the onboard operator through the output device when remote operation is active or when remote operation capability is available. This feedback mechanism provides continuous information about the operation mode, eliminating operator confusion and preventing unexpected activations while maintaining both onboard and remote control capabilities.
2Loss of information
If the system provides continuous notification to the onboard operator about remote operation status, then operator awareness and safety are improved, but information processing load and potential distraction increase
Solution Approach 1:
The notification system uses partial action by providing notifications only when necessary - specifically when remote operation is currently active or when remote operation capability is available. This selective notification approach maintains operator awareness without creating constant distractions or excessive information processing requirements.

AI summary
A work machine includes an actuator; an operator's seat; an operation device configured to receive an input by a first operator in the operator's seat to operate the actuator; processing circuitry configured to activate the actuator according to one of an input of a remote operation from outside the work machine and an input to the operation device; and an output device configured to perform at least one of notifying the first operator that the work machine is being remotely operated when the actuator is being activated according to the input of the remote operation, and notifying the first operator that there is a possibility of the work machine being remotely operated when there is a possibility of the actuator being activated according to the input of the remote operation.
