Space explorationRobots will not only help us on this world. But will also help us explore other worlds. In fact, space exploration is one of the most promising usages for robots. Since these machines are not so susceptible to the elements that could hurt or kill people. Robots can withstand radiation, heat, cold and can function without an atmosphere. Also robots have a much longer life span. So voyages to other solar systems as well as other planets would be possible. Robots could communicate with us and if something went wrong and destroyed, the space vehicle and a machine would be lost, not a human being.机器人用于空间探索机器人不仅会在这个星球上帮助我们，而且还将帮助我们探索别的星球。

实际上，空间探索就是机器人最有前途的用途之一，知识因为机器人对于机器人会使人伤亡的自然环境和条件不很敏感。

机器人能经受得住辐射，耐热又耐寒，而且能在没有大气的环境中的工作。

此外，机器人的使用寿命长得多。

因此不但可飞往别的行星，而且可飞往别的星系。

机器人可跟我们进行通信联络，要是有什么东西除了毛病，而损坏了宇宙飞行器的话，失去的是机器人而不是人。

科技英语原文及简单翻译

科技英语原文及简单翻译How ASIMO WorksIntroduction to How ASIMO WorksWant a robot to cook your dinner, do your homework, clean your house, or get your groceries? Robots already do a lot of the jobs that we humans don't want to do, can't do, or simply can't do as well as our robotic counterparts.Honda engineers have been busy creating the ASIMO robot for more than 20 years. In this article, we'll find out what makes ASIMO the most advanced humanoid robot to date.The Honda Motor Company developed ASIMO, which stands for Advanced Step in Innovative Mobility, and is the most advanced humanoid robot in the world. According to the ASIMO Web site, ASIMO is the first humanoid robot in the world that can walk independently and climb stairs.Rather than building a robot that would be another toy, Honda wanted to create a robot that would be a helper for people -- a robot to help around the house, help the elderly, or help someone confined to a wheelchair or bed. ASIMO is 4 feet 3 inches (1.3 meters) high, This allows ASIMO to do the jobs it was created to do without being too big and menacing.ASIMO's Motion: Walk Like a HumanHonda researchers began by studying the legs of insects, mammals, and the motion of a mountain climber with prosthetic legs to better understand the physiology and all of the things that take place when we walk -- particularly in the joints. For example, the fact that we shift our weight using our bodies and especially our arms inorder to balance was very important in getting ASIMO's walking mechanism right. The fact that we have toes that help with our balance was also taken intoconsideration: ASIMO actually has soft projections on its feet that play a similar role to the one our toes play when we walk. This soft material also absorbs impact on the joints, just as our soft tissues do when we walk.ASIMO has hip, knee, and foot joints. Robots have joints that researchers refer to as \degrees of freedom.\A single degree of freedom allows movement either right and left or up and down. ASIMO has 34 degrees of freedom spread over different points of its body in order to allow it to move freely. There are three degrees of freedom in ASIMO's neck, seven on each arm and six on each leg. The number of degrees offreedom necessary for ASIMO's legs was decided by measuring human joint movement while walking on flat ground, climbing stairs and running.ASIMO also has a speed sensor and a gyroscope sensor mounted on its body. They perform the tasks of:? ?sensing the position of ASIMO's body and the speed at which it is moving relaying adjustments for balance to the central computer These sensors work similarly to our inner ears in the way they maintain balance and orientation.ASIMO also has floor surface sensors in its feet and six ultrasonic sensors in its midsection. These sensors enhance ASIMO's ability to interact with its environment by detecting objects around ASIMO and comparing gathered information with maps of the area stored in ASIMO's memory.To accomplish the job our muscles and skin do in sensing muscle power, pressure and joint angles, ASIMO has both joint-angle sensors and a six-axis force sensor.Unless you know a lot about robotics, you may not fully grasp the incredible milestone it is that ASIMO walks as we do. The most significant part of ASIMO's walk is the turning capabilities. Rather than having to stop and shuffle, stop and shuffle, and stop and shuffle into a new direction, ASIMO leans and smoothly turns just like a human. ASIMO can also self-adjust its steps in case it stumbles, is pushed, or otherwise encounters something that alters normal walking.In order to accomplish this, ASIMO's engineers had to find a way to work with the inertial forces created when walking. For example, the earth's gravity creates a force, as does the speed at which you walk. Those two forces are called the \inertial force.\ground, called the \posture has to work to make it happen. This is called the \zero moment point\(ZMP). To control ASIMO's posture, engineers worked on three areas of control:? ?Floor reaction control means that the soles of the feet absorb floor unevenness while still maintaining a firm stance.Target ZMP control means that when ASIMO can't stand firmly and its body begins to fall forward, it maintains position by moving its upper body in the direction opposite the impending fall. At the same time, it speeds up its walking to quickly counterbalance the fall.?Foot-planting location control kicks in when the target ZMP control has been activated. It adjusts the length of the step to regain the right relationship between the position and speed of the body and the length of the step.ASIMO's Motion: Smooth MovesASIMO can sense falling movements and react to them quickly; but ASIMO's engineers wanted more. They wanted the robot to have a smooth gait as well as do something that other robots can't do -- turn without stopping.When we walk around corners, we shift our center of gravity into the turn. ASIMO uses a technology called \predictive movement control,\Intelligent Real-Time Flexible Walking Technology or I-Walk, to accomplish that same thing. ASIMO predicts how much it should shift its center of gravity to the inside of the turn and how long that shift should be maintained. Because this technolgy works in real time, ASIMO can do this without stopping between steps, which other robots must do.Essentially, with every step ASIMO takes, it has to determine its inertia and then predict how its weight needs to be shifted for the next step in order to walk and turn smoothly. It adjusts any of the following factors in order to maintain the right position:? ? ? ?the length of its steps its body position its speedthe direction in which it is steppingWhile reproducing a human-like walk is an amazing achievement, ASIMO can now run at speeds up to 3.7 miles per hour (6 kilometers per hour). In order to qualify as a true running robot, ASIMO must have both feet off the ground for an instant in each step. ASIMO manages to be airborne for .08 seconds with each step while running. Honda engineers encountered an entirely new set of challenges while trying to give ASIMO the ability to run. They gave ASIMO’s torso a degree of freedom to aid in bending and twisting so that the robot could adjust its posture while airborne. Without this ability, ASIMOwould lose control while airborne, possibly spinning in the air or tripping when landing.In order to make turns smoothly while running, the engineers enhanced ASIMO's ability to tilt its center of gravity inside turns to maintain balance and counteractcentrifugal force. ASIMO could even anticipate turns and begin to lean into them before starting the turn, much like you would if you were skiing or skating.ASIMO如何工作介绍如何工作。
