A major scientific breakthrough has occurred. Researchers from the University of Pennsylvania (UPenn) and the University of Michigan (U-M) have created a micro-robot smaller than a grain of salt. This research, published in the journal "Science Robotics," has given medical science a new direction.

This is the world's first tiny robot that can feel, think, and act independently. Its extremely small body is fitted with a computer, motor, and sensors. This robot runs on solar energy and uses two electrodes to swim.

According to researcher Mark Miskin, in the future, these robots could be used to deliver medicine to parts of the human body that doctors' instruments cannot reach. They would also help repair damaged tissue. They are made from silicon and titanium and coated with a glass-like layer to prevent damage from bodily fluids.

Nonetheless, this technology is yet in its infancy and not yet ready for application among humans. Scientist David Blau reveals that his next project will be to ensure that these robots have communication skills among each other, enabling them to work hand-in-hand as a team to combat big diseases.
