My childhood dream was to buid robots. I left that dream when I realized doing robotics mostly meant industrial arms and pick-and-place machines. Seeing developments over the last few years is inspiring, to say the least. Maybe it's time to consider coming back in.
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.
