VOA慢速英语 在FIRST机器人大赛中,学生和机器人进行竞赛

　　In January, the organization sent identical supplies for robots to each team. The teams had six weeks to build robots that could compete in the LUNACY game. The playing area had six robots, three on each team. Each robot had another vehicle, or trailer, connected to it. The robots had to pick up large balls and throw them into the trailers of opposing robots. The robots were moving on a surface where they could slide. An alliance of teams from California, Illinois and Michigan won the LUNACY competition.

　　A second competition involved building a robot that could travel on uneven surfaces, move objects with unusual shapes and withstand physical stress.

　　Another competition was for younger students, ages nine to fourteen years old. Eighty-four teams from twenty-seven countries competed with robots made with LEGO products. They had to design, build and program robots to explore the Earth's climate.
