No, it's not. If you want to build robots at home you will have to accept they will be vacuum cleaner level robots. For "real" robotics we need better software

No, it's not. If you want to build robots at home you will have to accept they will be vacuum cleaner level robots. For "real" robotics we need better software for controlling robot body. And that requires artificial brain. And we don't know yet how to build it, because we don't know how our brain works in enough detail yet.
