What you are watching
A simulated rover driving between the places on its map — the lake, the tree, the house, the mountain and its charging dock.
Every movement is commanded by an n8n workflow talking to ROS 2 over rosbridge. The trail colour is the rover's status LED.
What the rover offers
- Actions:
/rover/navigate_to,/rover/patrol - Services:
/rover/set_led,/rover/dock,/rover/emergency_stop - Topics:
/rover/status,/rover/battery,/rover/events
Why it moves on its own
- A scheduled workflow sends it on patrol.
- A battery watchdog turns the LED red and docks it below 25 %.
- Visitors can send it to a place through the destination form.
Workflows from the real rover
The robot above is a simulation. These are the actual n8n workflows that drive the physical FHNW rover — its drill, its arm and its tool changer — exported from the machine that runs them. They name hardware this simulation does not have, so they are here to read and download rather than to run. Internal hosts and identifiers have been replaced.
