Frontend Clause Samples

Frontend. The frontend solution will be based on a Webserver implemented using JSON and PhP.7 on an Apache server 2.4.28. The webserver will employ WebSocket protocol (TCP based) for faster operation. The partners have verified that JSON can be interfaced with ROS node using ROSBridge libraries. Rosbridge provides a JSON API to ROS functionality for non-ROS programs. There are a variety of front ends that interface with ROSBridge, including a WebSocket server for web browsers to interact with.
