It is good to visit trade shows on robotics. It gives you a good overview of the possibilities and the most important main stream developments in the industry.
Here is a recent clip from ‘Automate 2015′. It is fairly long, but I believe it provides a very nice overview of where the markets and the industry are at the moment. These are the things where people in robotics earn a living on, now and for the next five years or so. The Automate Show is held every two year in Michigan (US).
In the Netherlands there is a similar event every year, that I highly recommend: The Vision & Robotics trade show in Veldhoven. This year on June 1 en 2.
