Remote Mobile Body Control Using Posture-Based Input Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for mobile bodies, such as drones, are difficult for operators unfamiliar with the operation to navigate due to a lack of intuitive control, making it challenging to align the operator's intended movement direction with the mobile body's movement direction.
Innovation Solution
A control device and mobile body system that includes sensors to detect posture, generate and transmit posture data, and correct operation data based on relative postures to align the operator's intended movements with the mobile body's movements, allowing for intuitive remote control.

Engineering Contradiction Analysis
1Ease of operation
If traditional remote control operation is used where nose direction is regarded as forward movement direction, then the control system is simple, but it is difficult for operators unfamiliar with the operation to remotely operate the mobile body intuitively
Solution Approach 1:
The system detects the actual posture of the mobile body using sensors (accelerometers, gyroscopes) and feeds back this information to the control device. The operation data is then corrected based on the detected posture, creating a closed-loop feedback system that enables intuitive control while maintaining manageable complexity through automated posture compensation.
Solution Approach 2:
The patent introduces posture detection sensors and a correction mechanism as intermediaries between the operator's input and the mobile body's actual movement. This intermediary layer translates the operator's intended direction (based on control device posture) into corrected operation data that accounts for the mobile body's actual orientation, enabling intuitive control without requiring the operator to mentally calculate directional transformations.
2Ease of operation
If posture detection and correction mechanisms are added to enable intuitive control, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The posture detection sensors (accelerometers, gyroscopes) serve multiple functions: they detect the control device posture for operation data correction, track mobile body orientation for flight stability, and provide data for both control and navigation systems. This multi-functionality reduces the need for separate dedicated sensors, thereby limiting the increase in device complexity while achieving intuitive control.

AI summary
A control device according to one aspect of the present disclosure is a device that remotely operates a mobile body. The control device includes an operation unit and a sensor unit. The operation unit that performs reception of an operation for the mobile body. The sensor unit performs detection of a posture of the control device or the mobile body. The control device further includes a generation unit and a communication unit. The generation unit generates posture data of the control device on the basis of a result of the detection performed by the sensor unit. The communication unit transmits, to the mobile body, the posture data generated by the generation unit and operation data obtained by the reception performed by the operation unit.
