　　A little robot walks secretly in a large desert to look for proper areas. When it finds one,it reports the 1 and then plants seeds in the land. The robot, A'seedbot, could turn the desert 2 a land with grass and trees.

　　This tiny robot farmer was 3 by Mazyar Etehadi from the Dubai Institute of Design and Innovation. “I just hope that there are more plants, more green trees out there,”Etehadi said. "I think it was an easy way to come up with. But no one had 4 done it.”The problem of desertification(荒漠化) caused 5 to look for ways that were easier and more useful.

　　A'seedbot is about 20 cm long. Using solar 6 .the robot can recharge(充电)during the day and work by night. It has three 3D-printed 7 that can walk through sand in search of the proper areas to plant seeds. And farming companies or people like farmers could be 8 of A'seedbot.

　　And this little robot is far from alone. Earlier this year,a company 9 Flash Forest in Toronto thought of a similar method. They use the UAV(无人机）to plant trees ten times as quickly 10 a single worker. They hope to plant a full one billion trees by 2028.
