A delivery robot is carrying a parcel when it detects that its usual route is blocked. Explain how the robot makes decisions to complete the delivery safely.

The delivery robot completes the delivery safely in the following manner:

1. Its sensors detect the obstacle or blocked route and send this input to the controller.
2. The controller processes the sensor data and selects a safe alternate path to reach the destination. If no safe route is available, the robot stops.
3. The controller sends commands to the actuators to move the robot along the selected path. Updated sensor inputs provide continuous feedback so that the controller can adjust the path until the parcel is delivered safely.
