We've talked here before about the extremely important (and often-overlooked) DIY aspect of science. Scientists are makers. They have to be. The tools they need often aren't available any other way. Other times, the tools are available, but they're far more expensive than what you could construct out of your own ingenuity.
In this video, researchers at Cambridge build LEGO robots that automate time-consuming laboratory processes at a fraction of the cost of a "real" robot.
