When Google went on a robotics buying spree last year, a lot of people wondered what they were up to. But in reality, it is a fairly sensible direction for them to move in. Most of the technical challenges in getting commercial robots to market are software problems. Although Boston Dynamics, a military contractor that builds robots like 'Cheetah' in the photo still seems a bit of an odd purchase.

I just hope that becoming part of Google's ballooning bureaucracy doesn't stifle any of these companies' innovation.
