Team builds First Living Robots that can Reproduce

Spontaneous kinematic self-replication. (A) Stem cells are removed from early-stage frog blastula, dissociated, and placed in a saline solution, where they cohere into spheres containing ∼3,000 cells. The spheres develop cilia on their outer surfaces after 3 d. When the resulting mature swarm is placed amid ∼60,000 dissociated stem cells in a 60-mm-diameter circular dish (B), their collective motion pushes some cells together into piles (C and D), which, if sufficiently large (at least 50 cells), develop into ciliated offspring (E) themselves capable of swimming, and, if provided additional dissociated stem cells (F), build additional offspring. In short, progenitors (p) build offspring (o), which then become progenitors...

Living Robots built using Frog Cells

Computer-designed organisms. Left is simulated design, right is deployed physical green and red organism.
On the left, the anatomical blueprint for a computer-designed organism, discovered on a UVM supercomputer. On the right, the living organism, built entirely from frog skin (green) and heart muscle (red) cells. The background displays traces carved by a swarm of these new-to-nature organisms as they move through a field of particulate matter. (Credit: Sam Kriegman, UVM)

Tiny ‘xenobots’ assembled from cells promise advances from drug delivery to toxic waste clean-up. Scientists repurposed living frog cells – and assembled them into entirely new life-forms. These tiny ‘xenobots’ can move toward a target and heal themselves after being cut. These novel living machines are neither a traditional robot nor a known species of animal...
