Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robot control technologies over wide area networks face security issues due to insecure connections between control terminals and robots, and are limited in the actions they can perform, failing to meet user needs.
Innovation Solution
A robot control method and device that establishes a secure connection with a robot via a local area network by scanning a two-dimensional code, using a mobile terminal to acquire and send operation instructions via a wireless communication network, while interrupting and reestablishing the local area network connection to send working information to a remote monitoring center via a wide area network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If robot control is implemented over wide area network, then remote control capability is improved, but connection security deteriorates
Solution Approach 1:
The network connection is segmented into two distinct modes: local area network for control commands and wide area network for data transmission. This segmentation allows each network type to be optimized for its specific purpose while maintaining security boundaries between control and data planes.
Solution Approach 2:
A gateway device is introduced as an intermediary between the mobile terminal and robot. The gateway establishes secure local connections and manages wide area network communications, acting as a security buffer that prevents direct exposure of the robot to untrusted wide area network connections.
2Ease of operation
If robot control is implemented over wide area network, then remote control capability is improved, but robot action capability deteriorates
Solution Approach 1:
The system implements multi-functionality by enabling the robot to perform both traditional manufacturing tasks and new actions through mobile terminal control. The control interface supports diverse action types including movement, manipulation, and interaction, making the robot adaptable to various user needs while maintaining remote control capability.
Solution Approach 2:
The robot's action capability is made dynamic through real-time control from mobile terminals. Users can dynamically adjust robot actions, add new commands, and modify behavior patterns during operation, allowing the system to adapt to changing requirements without hardware modifications.
3Speed
If local area network connection is maintained continuously, then control responsiveness is improved, but information security deteriorates
Solution Approach 1:
The system uses periodic disconnection and reconnection of the local area network to transmit working information through the wide area network gateway. The connection is interrupted only when necessary for data transmission, maintaining security while minimizing impact on control responsiveness. After information transmission, the connection is reestablished to resume normal control operations.

AI summary
A robot control method, a device, and a remote control system. A mobile terminal establishes a connection to a robot by means of scanning a two-dimensional code and by means of a local area network. A remote monitoring and control center connects to the mobile terminal by means of a wide area network, and when the mobile terminal and the remote monitoring and control center send information to each other, the mobile terminal breaks off connection with the robot, thereby ensuring the security of information transmission. Operation instruction information from a user on an operation interface is acquired, the operation instruction information comprising a control parameter and an action execution parameter (S101), and on the basis of the set control parameter and the set action execution parameter, first control instruction information is generated (S103), and sent to the robot by means of a wireless communications network, in order to cause the robot to execute a corresponding action on the basis of the first control instruction information (S104). Operation of the robot is controlled by a variety of application programs, greatly satisfying user requirements. Different factories are connected to the remote monitoring and control center by means of a wide area network, thereby enabling work information sharing and monitoring and control, improving production efficiency.
