Vinny the robot

My robot was designed to make people smile, but how will my robot do that, who will it make smile? My robot is targeted for children's hospitals. The abilities of my robot are to dance, play music, read, and delivering things. Some of the ways it can make people smile is by interacting with the kids at the hospital by dancing with them, playing music, reading a book, or bringing them something to eat or drink. It can also make the staff smile by helping them too. It can deliver things to the patients if the staff are busy or need a break. How does the robot complete the tasks, what does it look like? The robot is 5 feet tall and 5 feet long. He has a speaker and a screen with two different color eyes and uses grouser wheels. He has two arms with claws to grab things.
