China's first intelligent grain leveling robot has been put into use in the country's granaries, freeing workers from arduous tasks and significantly raising efficiency.

The robot has two unique wheels with spiral blades, enabling it to travel at two meters per second on grain piles and flatten peaks. Even while carrying an adult's weight, it can maintain high-speed movement without sinking into the grain.
"It takes three people three days to complete leveling grain in a 1,400-square-meter granary like this, but three leveling robots can finish the job within one day. They can free people from hard labor," said Guo Fengmin, a designer of the robot.
The robot has a dustproof surface to prevent short circuits while working in a dusty environment.
The intelligent system also features laser radars and sensors installed in the granary to help robots avoid obstacles and collect data for route planning.
During collective operations, the system would use intelligent algorithms to plan the robots' routes in a unified manner, so that they won't collide with one another.
