#Google did not purchase the maker of the WildCat to penetrate the military world, but rather to expand into what it thinks will be the even more lucrative commercial robotics market. Even in areas such as agriculture, the demand for robotics is growing, with a report by WinterGreen Research suggesting that the market will reach $16.3 billion by 2020.
The issue is that there is no clear line between commercial and military developments in robotics. Just as with electronics and communications, many technological advances in robotics will be usable in both worlds. For example, the commercial sector is leading the way in developing automated driving technology, and the software that governs a self-driving car might well facilitate the design of a remotely driven tank. As off-the-shelf robotics become increasingly advanced, it will become easier for foreign militaries to close the gap in capabilities with the United States.
