A miniature device is driven by external vibrations, such as ultrasound. In the future, these robots will monitor the condition of the body and accurately deliver the drugs.

Mankind has long dreamed of tiny robots capable of penetrating the human body and eliminating the causes of diseases. New technologies make it possible to translate this idea into reality, but before it becomes a mass, it is necessary to overcome a number of obstacles - for example, to choose a suitable power source for medical nanorobots.

A team of researchers from the University of Technology in Georgia, the work of which says Engadget, was able to circumvent this problem. Scientists have created tiny robots that move due to vibration applied to them - for example, ultrasound.

Some medical robots are already able to navigate inside the body. For example, US researchers created an autopilot system for a robotic catheter.
