According to the thesis published on the 21st "Science · Robot" magazine, researchers at Cornell University in the United States installed the electronic "brain" smaller than the ant head of the ant head at 100 to 250 microns, so that they can be able to Walking independently without external control.

This innovation lays the foundation for the new generation of micro -equipment. These equipment can track bacteria, sniff chemicals, destroy pollutants, perform micro -surgery, and remove plaques in the arteries.

The "brain" of this new robotic robot is a complementary metal oxide semiconductor (CMOS) clock circuit. It contains 1,000 transistors, plus diode, resistor and capacitor array. Integrated the CMOS circuit to generate a signal, which generates a series of square wave frequencies of phase shifts, and then sets the robot's gait. The robotic legs are platinum -based brakes, and the circuit and legs are powered by photovoltaic.

The size of the new robot is only one thousandth of the large robots equipped with a large robot equipped on the CMOS electronic device, and can walk at a speed of more than 10 microns per second.

Researchers have previously developed a miniature robot that can crawl, swim, walk, and fold them, but there are always "lines" connected together. In order to generate exercise, this wire is used to provide current, or the laser beam must be directly focused on the specific location of the robot.

"In the past, we had to manipulate these 'lines' in order to get any form of reaction from the robot." Said Iteo Cohen, a professor of physics at Cornell University, said, "Now we have these brains, as if we can solve it from the puppet puppet. Open the rope, just like Pinocao has consciousness. "
