AMRs, cobots, drones and humanoids publish telemetry and events over MQTT, and your fleet manager sends missions back on their own topics. ConnectMQ connects every robot to your fleet manager, WMS or MES and the data pipeline for your physical-AI models.
No card required
You build the fleet manager and the AI pipeline, ConnectMQ moves the data. Robots publish once — often through an MQTT bridge next to ROS 2 on board — and your fleet manager, WMS or MES, AI data pipeline and safety alerts each subscribe in parallel. Missions go back on dedicated topics.
robots/amr-12/telemetry
robots/amr-12/mission/set
robots/amr-12/status (retained)A robot publishes its position, battery and state once. Your fleet manager, your AI data pipeline and your safety monitor each subscribe on their own — adding a new consumer never touches the robot. Missions travel back on their own topic, and only the fleet manager is allowed to publish there.
{"x":42.1,"y":7.8,"battery":64}robots/amr-12/mission/set{"goto":"dock-3"}A common MQTT setup in a warehouse: each AMR publishes telemetry, the fleet manager subscribes and sends missions back on the robot’s own topic. Robots and fleet manager both connect out to ConnectMQ over TLS.
14:32 AMR-12
Publishes its telemetry every second over the warehouse Wi-Fi. On its way to job 4471, the battery drops to 18 %.
robots/amr-12/telemetry → {"x":42.1,"y":7.8,"battery":18,"state":"moving"}14:32 Fleet manager
Subscribed through ConnectMQ: it moves job 4471 to AMR-07 and sends AMR-12 to dock-3, with QoS 1.
robots/amr-12/mission/set → {"goto":"dock-3","reason":"charge"}14:33 AMR-12
Its MQTT bridge hands the mission to the robot’s navigation; it drives to dock-3 and reports that it is docked.
robots/amr-12/mission/state → {"goto":"dock-3","state":"docked"}14:33 Shift lead
Gets a notification: AMR-12 is charging, and AMR-07 has already taken over the job.
A robot drops off the Wi-Fi: ConnectMQ publishes its Last Will robots/amr-12/status → offline as a retained message, so the fleet manager stops assigning it jobs right away.
