I always had a thing for robots and I loved Honda ASIMO when I was a child. I'm actually disappointing by how far the robotics technology has evolved. I haven't gone far researching. But it seems making apps for smartphones and making web services was cheaper and faster to spread throughout the world and gain better returns.
At least there are developments being made and I'm happy about them. It's also great to see that Microsoft Kinect 3D systems being used for things other tan just gaming. Good Hunt!
