With solar cell technology and a few more wings have the insect-like drone – taught its trade Robobee started flying completely without a power cord. Thanks to six tiny solar cells, weighing only 10 milligrams of spare part and an extra vinegar eliminating Harvard Macrobiotics Laboratory latest version of Robobee now power cords and can fly under its own power.
It is apparent from a new study published in the scientific journal Nature. The updated model of the insect-like drone – taught its trade called Robobee X-Wing. It now has four wings and weighs just 90 milligrams, which is less than a paper clip and has a blade range of about 3.5 centimeters.
Complete with the electronics needed to robot bee should be able to fly without cord, a photovoltaic matrix and a signal generator, weighing system 259 milligrams. The low voltage of the solar cells generates, 5 volts, is transformed with the help of an electronic circuit to the 200 volts pulses that are required to operate the Robobees mechanics.
To increase the aerodynamic efficiency powered blades in new Robobee of two aluminum reinforced piezoelectric actuator. So far can robot bee just fly a few seconds at a time?
But the scientists have a drone – taught its trade to cope with longer tours are several advantages that it is so small. It would then be able to be used to explore the different environments in a more efficient and significantly less energy-intensive way. Robobee could be used for instance for rescue missions, thinking of researchers.
