①Google's company, DeepMind, recently announced that their research team has created a ping-pong robot. This robot can play at the same level as human amateur (业余) players.
②The research team wrote about their work on a website called arXiv. A team member said, "This is the first learning robot that can play ping-pong as well as human amateurs. " The robot has a six-axis robotic arm that can move back and forth and side to side on a rail at the bottom.
③In 29 games against human players, the robot won 13 times, which is a win rate of 45%. The human players were all new to the robot, and their skill levels ranged from beginners to advanced players. The researchers said, "The robot lost all the games against high-level players but won all the games against beginners and 55% of the games against intermediate players."
④To make the robot play at a human level, the team used a layered and modular strategy(分层和模块化的策略).This means the robot can do basic skills like forehand topspin and backhand blocks. It also has a high-level controller that acts like a brain. During a game, it can choose the best moves based on the game situation, the robot's abilities, and the opponent's skills. After the game, the robot can analyze (分析) the data and improve its skills.
⑤The researchers noted that the robot still has some weaknesses. For example, it is not very good at backhand shots and has trouble with fast, high, low, or strongly spinning balls. They plan to improve the robot by making better control algorithms(算法)and better hardware.

One company has already begun a space programme with trips costing about $ 200, 000. In the future, these high prices should become more affordable, and more space guides will be needed. ▲Robot Mechanic: The robots available now mostly clean carpets or mow lawns. Someday these machines will become cheaper, and more families will be able to buy robotic personal assistants or companions. Some people will work as robot mechanics to take care of the mechanical problems of these robots. www. sunshineschool. englishnewspaper. com.cn |
