Mobile Robot Network Connection State Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network disconnection between robots and control servers leads to reduced safety and productivity, as it prevents real-time monitoring and control of robots, causing them to remain in infinite standby states and potentially obstructing other robots or human movement.
Innovation Solution
Implementing a robot control method that uses a communication device to communicate with a control server based on multiple communication protocols, determining the network connection state, and controlling robot operations accordingly, ensuring safety and service quality by performing exception scenarios and minimizing data loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single communication protocol is used between robot and control server, then communication simplicity is maintained, but reliability and service quality deteriorate during network disconnection
Solution Approach 1:
The robot is configured to communicate with the control server using multiple communication protocols simultaneously. The communication device includes a first communication unit operating via a first protocol and a second communication unit operating via a second protocol, enabling the system to maintain service quality and reliability through protocol diversity while managing network disconnection scenarios.
2Reliability
If network connection state is determined once, then response time is reduced, but accuracy and safety of robot operation deteriorate
Solution Approach 1:
The robot performs preliminary determination of network connection state at specific intervals before actual operation begins. The controller determines the connection state at least twice based on settings from different communication protocols, establishing baseline knowledge of network status in advance to ensure accurate and safe robot operation without significant time delay.
3Productivity
If robot waits for control server commands, then command accuracy is maintained, but productivity and efficiency deteriorate during network disconnection
Solution Approach 1:
The robot performs self-service operations by autonomously determining its own network connection state and executing evasive movement commands based on locally stored information when network disconnection occurs. The controller stores collected data during operation and uses it to maintain productivity without requiring continuous external commands, while the communication device ensures data integrity through protocol-based verification.
4Reliability
If network connection state is determined multiple times, then service quality and safety are improved, but communication overhead and processing time increase
Solution Approach 1:
The robot performs network connection state determination at periodic intervals rather than continuously. The controller determines connection state at least twice based on protocol settings, balancing the need for reliable service quality with energy efficiency by spacing out determination operations while maintaining sufficient monitoring frequency for safe robot operation.
