Tiny, Programmable, Living Robots Guest: Sam Kriegman, Postdoctoral Researcher, University of Vermont Xenobots are computer-designed and controllable microorganisms built out of stem cells from a frog that open the door for some amazing technology and human health benefits down the road. Microbots, Move Out! Guest: Eric Diller, Assistant Professor of Mechanical Engineering, and Lead, Microrobotics Labratory, University of Toronto Innovation in tiny robot technology has resulted in microbots the size of a pinhead; they are remarkable for their minisculity (which could possibly allow them to move through tiny passageways in the human body), their ease of construction, and their precise maneuverability.
