Wireless Robot Cell Control Using Broadcast Safety Data

The patent extracts the safety-critical communication functions from the centralized cloud controller and implements them locally in each robotic device. Each device independently receives broadcast/multicast control data and autonomously executes safety actions without relying on continuous two-way communication with the controller, thereby eliminating the need for complex field bus infrastructure while maintaining safety reliability.

The patent introduces broadcast and multicast wireless transmission as an intermediary mechanism that enables one-to-many communication from the cloud controller to multiple robotic devices simultaneously. This intermediary approach replaces complex point-to-point field bus connections with a simpler wireless broadcast infrastructure, reducing device complexity while maintaining communication reliability for safety-critical data.

The patent implements preliminary action by having each robotic device pre-process and autonomously execute safety actions based on broadcast control data before any potential collision or unsafe situation occurs. The devices continuously monitor their environment and independently trigger protective stops or avoidance maneuvers without waiting for controller confirmation, thereby eliminating communication delays while maintaining ease of remote operation.

The patent enables self-service by allowing each robotic device to independently handle safety-critical decisions and actions without requiring continuous communication with the cloud controller. Each device autonomously interprets broadcast control data, monitors its own state and environment, and executes necessary safety actions, thereby eliminating communication delays while maintaining centralized control architecture.

The patent applies dynamics by transitioning from static, centralized safety mechanisms to dynamic, distributed safety actions. Each robotic device dynamically processes broadcast control data in real-time and autonomously adapts its behavior based on current cell state, enabling existing safety logic to function effectively in wireless-controlled environments without requiring fundamental redesign.

The patent segments the centralized safety control function into distributed safety actions that reside in each individual robotic device. Instead of a single centralized controller making all safety decisions, each device independently executes safety logic based on its own state and broadcast control data, making the safety system adaptable to wireless control while maintaining collision avoidance capabilities.
