Robot Frogs

Did You Know? Scientists use stem cells from frogs to build first living robots. US-based researchers have created living machines from cells cultured from African claw frogs. The machines are less than 1mm long and can be programmed. When damaged, the robots can heal themselves, and when their tasks are done, they can die and decay. These features make them ideal for tasks like cleaning up microplastic pollution in the oceans, locating and digesting toxic materials, drug delivery in the body, or removing plaque from artery walls.

The robots are designed by an evolutionary algorithm that runs on a supercomputer. It runs tests in virtual environments to see which designs are the best, and then after about 100 generations, a design is chosen to be built in the lab. They have blood vessels, nervous systems, and sensory cells. Some groups have raised concerns over the ethics of the creation and use of these robots. #trianglecompudocs #didyouknow #cyborgsarereal
