人类研制机器人已经有十多年的历史了。这些机器人已经或将广泛用于许多对人类有危险的环境中。你能想像将来有一天,机器人能和宇航员一起在空间工作吗?美国国家航宇局约翰逊空间中心准备耗资300万美元研制一种太空机器人,取名为“机器宇航员”(Robonaut),它们将在不久的国际空间站任务中大显身手。 “机器人宇航员”的外形就象美国《星球大战》系列电影中专门负责追捕星际逃犯的Boba Fett,与人的大小相似,具有头、躯干、两个上臂和五个手指的手。它的“皮肤”由类似制造宇航服的纤维材料制成。与人的双手一样,这双灵巧的机械手能使用宇航员常用的各种工程工具,在有重力的环境下能举起9.5千克重的物体。与人相似的是,“机器宇航员”也有一个树形中枢神经系统,是由传感器组成的网络。它的每个手臂上有150多种传感器,将数据实时传送回“机器宇航员”体内的中央处理装置中。
Human development robot has more than ten years of history. These robots have been or will be widely used in many environments that are dangerous to humans. Can you imagine the robot working with astronauts some day in the future? The NASA Johnson Space Center prepared a $ 3 million space robot called Robonaut, It will be in the midst of a mission to the International Space Station in the near future. “Robot astronaut” looks like the Boba Fett in the Star Wars movie dedicated to the pursuit of interstellar fugacities, similar in size to humans, with head, torso, two upper arms and five fingers in hand. Its “skin” is made of fiber material that resembles spacesuits. Like human hands, these dexterous robots use a variety of engineering tools commonly used by astronauts to lift objects weighing up to 9.5 kg in a gravitational environment. Similarly, “machine cosmonauts” also have a tree-shaped central nervous system, which is a network of sensors. With more than 150 sensors on each arm, it transmits data in real time to the central processing unit in the Machine Astronaut.
