Observe the workflow of a mobile robot, which is used in a warehouse to transport packages and create similar workflows for different robots in the industry.

Step 1: Request: Receive transport request from the operator or warehouse manager.

Step 2: Navigation: Navigate in warehouse by using sensors and cameras. The sensor and camera input goes to the controller. It generates signals for the actuators to avoid obstacles and find a suitable path.

Step 3: Pickup the package: After reaching the destination, the robot uses a gripper to pick up the package. The package may be located at a shelf or conveyor.

Step 4: Send package: After picking up the package, the robot sends the package to the desired location, which may be an area within the warehouse, loading dock, or shipping area. For this, again, the robot navigates with the help of sensors, actuators and manipulators, and all the control signals are generated by the controller of the robot.

Step 5: Deliver package: The robot delivers the package to the designated location by releasing grippers or any other mechanism.

Step 6: Return: The robot goes back to its starting location or charging station and waits for the next request.

Sensors are used to measure environmental variables.
