Choco-Bot: Piece by Piece

My robot’s name is Bob the Choco-Bot. Bob’s designed to make someone smile. He is a machine that will bring someone chocolate whenever they ask for it. Bob will be assembled with metal and screws. He’ll have wheels that rotate both directions and go forward/backwards. He’ll have two arms with hands that rotate to pick up the bucket that he will carry around. He’ll have a square-like body with a spherical head. In his eyes, he’ll have two cameras so he can recognize his surroundings. He will have two “ears”. Each ear will have a hearing sensor. Bob will be automated, so he’ll have a computer system built into his head. There will be certain commands he’ll understand, one being “I want chocolate”, etc.. Bob will be able to fill out the person’s commands by locating the chocolate, which will also have to be programmed into his computer system.
