Nano-Robotics
Research
Nano-robotics is a field of technology which will eventually design tiny robots whose components are close to the scale of a nanometer. Nanotechnology has already had an impact on electronic products including nano-transistors, nano-diodes, OLED and plasma displays.
Advantages
A lot of robots will take up very little space, Nanorobots can be implanted into people to help cure diseases
Risks
If a nanorobot breaks down inside a human body, it could cause lots of trouble Their development will be very expensive Such tint robots can get easily lost
Media
Application for Solving World Hunger
In the future, farms may have an army of tiny robots which are designed to kill specific bugs and treat diseased plants
