Remote Robot Firewall Bypass via Communication Server

The patent uses a communication server as an intermediary between the robot and remote control station. The server establishes relay connections that allow communication through the firewall without requiring the firewall to block incoming connections directly to the robot. The server acts as a mediator that translates and forwards messages between the protected robot and external users.

Instead of allowing incoming connections from the internet to reach the robot directly (traditional approach), the patent inverts the approach by having the robot initiate outgoing connections to a communication server. This reversal allows the robot to maintain connectivity while remaining protected behind the firewall, as outbound connections are typically permitted by firewalls.

The communication server serves as a mediator that bridges different networks. It receives connections from the robot on the local network and establishes separate connections to remote control stations on external networks, thereby enabling reliable communication across network boundaries while maintaining firewall protection.

The patent introduces an additional network dimension by deploying a communication server on a separate network infrastructure (such as the internet). This creates a multi-dimensional communication architecture where the robot remains on the protected local network while accessing remote stations through the server on a different network, thus maintaining both network flexibility and communication reliability.
