Douglas Blackiston holds a petri dish full of Xenobots, micro-scale "living robots" made from embryonic frog stem cells, in a lab at the Allen Discovery Center at Tufts University in Medford, Massachusetts, on Thu., Sept. 9, 2021. Blackiston is a Senior Scientist at the Allen Discovery Center at Tufts University, and Sam Kriegman, the other scientist involved in the creation of xenobots, is a postdoctoral fellow at the Weiss Institute for Biologically Inspired Engineering at Harvard University and the Allen Discovery Center at Tufts University. 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.
