Assume that you are leading a team that is assigned to design a remote controlled robotic humanoid system. The system composes of two distinct units: a robot unit (hardware/software) that can move freely on a set of wheels, and a remote-control unit (e.g. a smart phone app). The two units communicate via a wireless link. The minimum requirements for the robot unit are: Basic movements: Move Forward, Move Backward, Turn Left, Turn Right, and Wait Basic Human-machine interfacing (HCI): Greet when turned on, Transmit video from a webcam to the remote-control unit for real-time monitoring. Provide the followings in terms of UML: a) A list of Structural Things that is required at the minimum for the system. b) List 3 use cases for the system. c) Draw the following UML diagrams: 1. Class diagram 2. Deployment diagram 3. Use-case Diagram (corresponding to 1b) 4. StateChart diagram (at least 3 corresponding to b) 5. Sequence diagram (corresponding to 1b)
