FleetMeshCompare the job of the interface
Read each column with its version boundary: VDA 5050 v3.0.0 and the MassRobotics v1.0 PDF with its pinned repository materials. A feature outside one interface's scope is not evidence that the interface is inferior.
| Axis | VDA 5050 v3.0.0 | MassRobotics |
|---|---|---|
| Command / control | Fleet-control-to-robot orders and instant actions, with robot feedback and defined interaction rules. | Identity and operational information exchange; not a general command interface for controlling another vendor's robot. |
| Telemetry / state sharing | State, visualization, connection and factsheet messages within the controller/robot relationship. | Identity and status reports covering location, motion, operational state and optional operational context. |
| Tasking | Orders describe nodes, edges and actions for execution. Selecting and scheduling business work still belongs to the surrounding system. | Destinations and paths can share intention. A complete dispatch, task allocation and execution-control protocol is not provided. |
| Traffic coordination | Communication primitives support coordination, including route releases and v3 zone concepts. A traffic-planning algorithm is not supplied. | Shared robot observations may inform a separate coordinator. Reporting does not implement central arbitration or exclusive reservations. |
| Transport | MQTT with JSON payloads and defined topic conventions. | JSON over WebSockets in the v1.0 specification. |
| Schema | Eight official message schemas in the selected snapshot, declaring JSON Schema Draft 2020-12. | A published JSON schema describes identity/status structures. This snapshot does not declare its schema dialect. |
| Deployment intent | A common control interface for mobile robots and fleet control in intralogistics. | Shared information about heterogeneous AMRs operating in a common environment. |
| Interoperability scope | A common protocol and behavioral contract, still requiring compatible features, versions and integration tests. | A common reporting vocabulary, still requiring shared coordinate interpretation and consumer/producer agreement. |

Start with who makes the decision
If a system must assign robot work through a common control interface, examine the VDA controller/robot contract and the capabilities each implementation supports. If the immediate need is a shared view of independently operated AMRs, examine the MassRobotics reporting model. These are requirement questions, not automatic product recommendations.
For either path, write down who schedules work, who authorizes movement, who owns maps and who handles failure. Neither document is a replacement for a complete system design, commissioning process or safety assessment.
FleetMesh interpretation of the documented scopes; no vendor compatibility is asserted.
The interfaces can sit at different boundaries
A proposed architecture might use a controller-facing interface for execution and a separate reporting interface for shared awareness. That is an architectural possibility, not a standardized plug-and-play bridge between VDA 5050 and MassRobotics.
Any adapter needs explicit rules for identity, coordinate frames, timestamps, lost connections and state meanings. Information lost during translation must remain visible. Do not translate a reported destination into an authorized order, or a reported path into a traffic reservation, without an independently defined decision process.
FleetMesh architecture guidance. Neither specification is claimed to define this adapter.
Schema-valid is not compliant
Schema-valid does not mean VDA 5050 compliant.
Passing JSON Schema validation only confirms message structure. It does not prove correct robot behavior, interoperability, safety, timing, state handling or protocol semantics.
Our Message Explorer checks only VDA 5050 v3.0.0 message structure against pinned official schemas. It does not validate MassRobotics messages, simulate a controller, inspect an MQTT session or certify a robot.
Official PDF wins. For VDA 5050, the official repository explicitly gives the published VDA document precedence if GitHub material differs. A tool result must never reverse that priority.
