Scientists create 'army of tiny walking robots' in major breakthrough

Scientists have been able to create an army of tiny, walking robots in a new breakthrough. The objects are the first microscopic robots that are made out of semiconductor components. That allows them to be controlled and forced to walk with standard electronic signals, allowing them to be integrated into more traditional circuits. The researchers behind the discovery now hope that they can be built into even more complex versions. That could allow for future robots to be able to be controlled by computer chips, produced en masse – and built in such a way that they could travel through human tissue and blood, acting like surgeons, the researchers say.
