Scientists use stem cells from frogs to build first living robots

Scientists use stem cells from frogs to build first living robots.

 

They've listed a number of positive things such living robots could do, but I think that as they advance in capability, they'll probably be used to deliver small amounts of deadly poison to enemies of powerful people. And eventually, to create slaves.

 

From the article:

The robots, which are less than 1mm long, are designed by an “evolutionary algorithm” that runs on a supercomputer. The program starts by generating random 3D configurations of 500 to 1,000 skin and heart cells. Each design is then tested in a virtual environment, to see, for example, how far it moves when the heart cells are set beating. The best performers are used to spawn more designs, which themselves are then put through their paces.



Because heart cells spontaneously contract and relax, they behave like miniature engines that drive the robots along until their energy reserves run out. The cells have enough fuel inside them for the robots to survive for a week to 10 days before keeling over.
