Coaty enables powerful any-to-any collaboration between your autonomously acting IoT devices, people, and services in ever-changing scenarios.
Key features
Distributed data - remote operations
Discover, query, share, and update data on demand in a distributed system. Request execution of context-filtered remote operations.
Powerful communication patterns for any-to-any collaboration
Use event-based communication flows with one-to-many and many-to-many request-response patterns to realize decentralized prosumer scenarios. Coaty’s standardized communication event patterns are build on top of exchangeable open-standard publish-subscribe messaging protocols such as MQTT or WAMP.
Query anywhere - retrieve anywhere - persist anywhere
Seamlessly query distributed domain-specific data across decentralized components. You can retrieve data from arbitary data sources by use of a Unified Object Storage API which is part of the framework.
Smart routing of IoT data based on context
Dynamically route IoT (sensor) data from sources to actors, i.e. consumers based on context. Coaty provides rule-based routing using smart backpressure strategies negotiated between sources and actors.
Incremental & dynamic scenario evolution
Coaty removes the need for a central coordination authority by decoupling interaction between agents. You can dynamically add new agents and new features without distracting the existing system in order to adapt to your ever-changing scenarios.
Lightweight & modular architecture
Coaty favors a declarative programming style with inversion of control and distributed lifecycle management. Choose from a set of core and specialized modules to achieve operational simplicity with minimal dependencies. Connect to heterogenous system landscapes by extensible connectors.
Reactive Programming for asynchronous event handling
Coaty adopts the Reactive Programming paradigm to handle incoming asynchronous events in context. It raises the level of abstraction of your code so you can focus on the interdependence of events that define the communication business logic.
Typed object model
Model your domain data with Coaty’s platform-agnostic typed object model. It provides an extensible hierarchy of core object types for distributed data exchange. Coaty objects are JSON compatible to be interoperable between languages and platforms.
Works across languages and platforms - even in browsers
Coaty applications are interoperable between framework implementations. Coaty JS is the reference implementation targeted at JavaScript and TypeScript. It runs not only in Node.js, but even in mobile and web browsers.
Ready to use
Get started with Coaty by using its best practice examples as application skeleton. In addition, Coaty comes with all you need to know: a developer guide, coding style guide, and complete framework API documentation.
Open source and free
Coaty is being developed on GitHub. It is open source which allows you to modify and extend it according to your needs. Moreover, its permissive, industry-friendly MIT license facilitates commercial use.
Reference projects
Decentralized job negotiation of Autonomous Guided Vehicles
A driverless transport system where all jobs are managed dynamically and without central authorities. Coaty builds the communication foundation to advertise jobs, discover necessary resources, and negotiate assignments in a decentralized way. Operation autonomy in technical and business sense is transferred as close as possible to heterogenous devices (e.g. SIMOVE, proANT).
SIMOVE - Maximize your Production Flexibility
Using the SIMOVE AGV system platform, Siemens demonstrates how AGV machine builders benefit from reduced planning and engineering effort as well as shorter commissioning times, and how users can design their logistics processes more flexibly and productively. Coaty will be used to realize next generation solutions that provide operation autonomy in decentralized dynamic ad-hoc scenarios.
FlowPro - AI and IoT powered Future Micrologistic Ecosystems
The FlowPro project researches technologies for future micrologistic systems integrating decentrally organized heterogeneous ground and air-bound autonomous transport units. Coaty is used to implement the interaction backbone for the envisioned self-organizing logistic multi-agent system.
pebbles - Managing decentralized energy systems by regional peer to peer energy trading based on blockchain
The pebbles project requires a decentralized implementation of a transaction platform for energy trading. Coaty is used to implement the first version of the communication backbone and will step by step be integrated with the planned Blockchain developments to a hybrid transaction platform.
SIEMoji – The AR-Take on diagnostics
SIEMoji combines Augmented Reality, smartphones, and IoT technology with the expressive language of social media to reach a new level of user experience for on-site industrial diagnosis. Coaty builds the communication foundation in order to discover all required data artifacts dynamically and ad-hoc and interprete in the right context for the mesh app SIEMoji.
IIoT Bazaar - Decentralized marketplace for industrial edge applications
IIoT Bazaar combines Industrial IoT, Augmented Reality, and Blockchain. Coaty builds the communication foundation to reach a software and device ecosystem which allows for advanced user experience, new fine-granular payment concepts and completely new business models for the industrial domain.
Digital Worker – An ecosystem to ease daily work in manufacturing and improve speed, quality, and safety
Coaty builds the communication foundation of Digital Worker applications, dynamically interconnecting smartphones, tablets, wearables, and glasses with machines, edge and cloud services in a context and task aware fashion. The Digital Worker always has the right information and control functionality available.
