Flying Robot

A story about a boy in Tokyo making a flying robot
One day, four boys living in Tokyo gathered after school. They were named Takashi, Hiroshi, Kenta, and Yuuki. They were interested in science and robotics and dreamed of building their own flying robot one day.
Takashi said. "Hey guys, we already know what we can do. Why don't we use it to build a flying robot together?" Hiroshi replied, "That sounds like a lot of fun!"
