For Bloomberg Businessweek, I spent an afternoon in the Allen Discovery Center at Tufts University with scientists Sam Kriegman and Douglas Blackiston, who developed Xenobots, micro-scale "living robots" made from frog embryo stem cells.Kriegman designed the artificial intelligence system that created the structure for the xenobots and Blackiston is responsible for building them. As Blackiston put it, "Sam tests [the robots and other experimental setups] in the virtual world, and then I test it in the real world." The machines are capable of autonomously performing simple tasks including navigating mazes and gathering small particles together.

A big thanks to Jane and Dietmar at Bloomberg for the assignment!
