How About A Walking Humanoid B

How about a walking humanoid but with grippers on its head and 3 feet connected to a spinning servo on each side and a gyroscope on the neck and (if possible) a way for it to follow you so it can take your stuff and be sort of like a minion who can go up stairs. That way if you need to take the grocerys to your apartment and you have a lot, it can grab a bag on its head and take it up the stairs for you. You could even connect it to your phone and give it a microphone so it can do things like hand free text. So its basically a 3rd/4th arm.
