$1.$ Consider a walking robot that has two legs and two arms. The robot walks towards a screen that has three buttons $($red$,$ yellow, and green$).$ On the path towards the screen, a block and a chair block the robot. The robot observes the block and makes a right turn of $55$ degree, walk $10$ cm and make left turn of $14$ degree walk forward $($to the screen$).$ Once observes the chair, after $30$ cm travels, an adjustment of $127$ degree to the right is needed. After $35$ cm$,$ robot makes left turn of $110$ degree towards the screen and finally reaches the target. The robot lifts left arm and uses color sensor to detect the color on the screen, put down the left arm and lift right arm to press button based on the detected color of the button. Prepare a state diagram of the above scenario using correct UML notations. Please use correct UML notations!!!
