Apr 1, 2021 Scientists have created a new generation of biological – or living – robots that can assemble and heal themselves. The latest version of Xenobots are faster, live longer, and can now record information. Last year, a team of biologists and computer scientists from Tufts University and the University of Vermont (UVM) created tiny self-healing biological machines from frog cells called Xenobots that could move around, push a payload, and even exhibit collective behaviour in the presence of a swarm of other Xenobots. Now, the same team has now created life forms that self-assemble a body from single cells, do not require muscle cells to move, and even demonstrate the capability of recordable memory.
