The robots can measure wind speed, air pressure, humidity, sand vibration and wind erosion.
The robots, which are equipped with solar panels, use microwaves to relay data over an area of 25 kilometers. They can run for one hour.
Ningxia, a dry and barren region in northwest China, borders Tengger Desert, China’s fourth largest desert, which stretches over 43,000 square kilometers.
