Robot Task State Machine
The states of an autonomous mobile robot doing pick tasks: idle, navigating, picking, delivering, charging, and recovering from faults and blocked paths.
Drawing diagram…
What this diagram shows
- Low battery sends the robot to charge between tasks
- Blocked paths trigger re-planning before raising a fault
- Emergency stop overrides every other state
Prompt used
State machine for an autonomous warehouse robot: Idle, Assigned a task, Navigating to the pick location, Picking, Navigating to drop-off, Delivering, back to Idle. Low battery below 20% sends it to Charging. A blocked path goes to Replanning; if replanning fails 3 times it raises Fault and waits for an operator. Emergency Stop can happen from any active state.
