Motion Request Verification for Remote Medical Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional master-slave control systems lack safety verification for remote operation of devices, particularly in scenarios where the device's motion request execution may pose risks to the operation target, such as in remote medical procedures.
Innovation Solution
An information processing apparatus with a motion request verifying unit that assesses the safety of device operations by using device state information and target state information, updated in real-time, to ensure safe execution of motion requests, incorporating a simulation device to verify the safety of the operation target before executing the request.

Engineering Contradiction Analysis
1Ease of operation
If a simulation device generates a virtual environment for the slave device and presents it to the master device, then the master device can control the slave device in a remote area, but no safety verification is performed for the motion request execution result
Solution Approach 1:
The system performs preliminary simulation of the motion request in the virtual environment before executing it on the actual slave device. The simulation device predicts the execution result and verifies safety conditions in advance, preventing unsafe motions from being executed on the real device.
Solution Approach 2:
The simulation device acts as an intermediary between the master device and the slave device. It receives motion requests from the master device, simulates them in the virtual environment, and only transmits approved requests to the slave device, thereby ensuring safety verification.
2Measurement precision
If device side information is updated in real-time between the first point in time and the second point in time, then the accuracy of safety verification is improved, but the complexity of the information processing system increases
Solution Approach 1:
The simulation device performs multiple functions using the same updated device side information: it reconstructs the virtual environment, simulates the motion request, and verifies safety conditions. This multi-functional approach avoids the need for separate processing systems for each function.
Solution Approach 2:
The system continuously updates device side information and uses this feedback to reconstruct the virtual environment and re-simulate motion requests. This feedback mechanism ensures that the simulation reflects the current state of the slave device, improving verification accuracy.

AI summary
There is provided an information processing apparatus that includes a motion request verifying unit controlling execution of a motion request for a device, on the basis of the motion request based on device side information including device state information indicating a state of the device at a first point in time and target state information indicating a state of an operated target, and device side information updated during time after the first point in time and before a second point in time at which the motion request is received.
