Football is so popular in China. Almost everyone is interested in the sport,young and old, boys and girls,and
now even robots.
Last week at Hangzhou Guangming Middle School, kids from several schools played football with their robots.
The robot football is very different from human football. Only two robots play in each match. The field is as big
as a ping-pong table. One half is black and the other is white. Each robot tries to catch the " football" and push it
into the goal. The robot with more goals won.
Gao Linge,a boy from Guangming Middle School, helped make one of the robots for the match.
" My school bought the main board (主板) ," said Gao,14. " Then I decided what my robot looked like and made
a computer programme for it. "
Gao's robot was eight cm tall and had two arms.It had four sensors (感应器 ) to " see " and "kick" the football.
Ying Xuehai, a 12-year-old student from Gao's school,also made a robot. His robot played against Gao's.The match
decided who would go to the final game. Ying lost the game. So he gave many of his robot's parts to Gao.
Even with the help, Gao's robot didn't win the final. It played well in the first five minutes.
Then it slowed down. By the end of the match,it could hardly move.
What was wrong?
Gao and Ying found the problem. Their robot ran out of batteries(电池) !
" We'll solve the problem and beat the other schools next time ! " said the two boys.
