I Want To Create A Robot That

I want to create a robot that can move around and interact with our environment as a human could. It can open doors, it can pick things up and set them down, it can walk around, etc. I also want to infuse it with a chat bot so you can talk to it and it can respond to you with its own personality. Using voice commands you can ask it to get you something from another room, or give you an update on the weather, or order takeout from a restauranr. It would need sensors like some cameras so it can look around and recognize objects and people, some sonar sensors on the legs/base, and some touch sensors. I just want to make a robotic companion essentially.
