I feel like robotics in a few years is what big data is today. So what is it that one should be doing to get ready to jump into robotics in a few years?
Most of the people I run into today working on "big data" could still effectively fit the workloads in a single powerful MySQL box.
Also, play with Arduino some.
Actually, a lot of the math for 3d game engines transfers directly to robotics. Matrix coordinate transformation to/from each joint to figure out where/how to place it.
