Application Deployment and Maintenance Strategies Node.js
Robots and devices from Festo, controlled in the FTL language, are not limited to replaying fixed motion paths. Thanks to the ability to communicate with vision systems (2D/3D) and sensors (e.g., force), they can actively adapt their operations to the current situation on the line. Below we present how FTL supports such intelligent collaboration:
Containerization and orchestration
