Multi-Robot Task Relay for WiFi Disconnection Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In logistics robotics, the instability of WIFI networks causes robots to lose heartbeat connections, leading to discontinuous task processing and low success rates when task information cannot be sent to disconnected robots.
Innovation Solution
Implementing a task processing method that uses bidirectional communication modules, where a target sending robot is determined based on historical and current positions of connected robots to relay task information to disconnected robots, ensuring continuity and improving success rates through a combination of WIFI and long-range radio communication modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If WIFI network is used for communication between task processing device and robots, then communication speed and data transmission capability are improved, but network stability deteriorates causing heartbeat connection loss
Solution Approach 1:
The patent introduces a dual communication module system where robots have both first communication modules (WIFI) and second communication modules (long-range radio). When WIFI connection is lost, the system automatically switches to long-range radio communication as an intermediary channel to maintain heartbeat connections and task information transmission, thus resolving the contradiction between WIFI's high speed and poor stability.
2Loss of information
If robot loses heartbeat connection with task processing device, then task information delivery fails, but task processing continuity is disrupted
Solution Approach 1:
The patent implements preliminary action by establishing dual communication modules in advance before connection loss occurs. The system proactively configures both WIFI and long-range radio communication capabilities, and pre-defines automatic switching mechanisms. When heartbeat connection is lost, the task information can immediately be transmitted through the pre-configured long-range radio channel, ensuring task processing continuity without disruption.
3Device complexity
If single communication module is used, then device complexity is reduced, but communication reliability under varying conditions deteriorates
Solution Approach 1:
The patent applies universality by designing robots with multi-functional communication capabilities. Each robot is equipped with both first communication modules (WIFI for high-speed data transmission) and second communication modules (long-range radio for stable heartbeat connections). This multi-functionality allows the communication system to adapt to different conditions: using WIFI when available for fast communication, and switching to long-range radio when WIFI fails, thus improving communication adaptability without significantly increasing operational complexity.
