Xenobots: An evolutionary epoch?

The world's first-ever living robots- Xenobots, were developed by a group of researchers from the University of Vermont and Tufts University, USA. These bots are named after the African clawed frog, Xenopus laevis from which their stem cells were harvested. Under one millimeter in size, these bots are self-healing and small enough to travel inside a human body. They can move forward, backward, and also spin in circles. While these Xenobots could create an evolutionary epoch, researchers believe that they also have potential risks, and experimenting with such living cells can create unforeseen consequences. The researchers from the University of Vermont and Tufts University wanted to figure out if they could take real-life cells and make them behave in a specific way, much like a traditional robot made of other materials.
