1. Introduction: Redefining the Human-Machine Interface The history of wearable robotics has long been dominated by the visual and mechanical language of the exoskeleton: rigid, anthropomorphic frames of metal and carbon fiber, powered by heavy electric motors or hydraulics, designed to envelop the human limb and force it into motion. This design philosophy, popularized by science fiction and pursued vigorously by engineering labs for half a century, operates on the principle

Abstract The emergence of Xenobots—programmable biological machines derived from Xenopus laevis  embryos—represents a paradigm shift in the fields of robotics, synthetic biology, and developmental biophysics. First unveiled in 2020 by a multi-institutional team from Tufts University, the University of Vermont (UVM), and Harvard’s Wyss Institute, these constructs challenge the traditional dichotomy between the "born" and the "made." Unlike conventional robots constructed from
