英语翻译Robotic Bodies Regardless of how the base of the robot is built,it is important that the upper body be built well.Many robots have functioning arms that are capable of performing tasks such as picking objects up and disarmimg a bomb.Both the arms and legs of robots move by implementing a method called robot kinematics.As any one robotic arm or leg moves,other components of that arm or leg will move with it.For example,in a human body,if a shoulder is rotated,its crresponding wrist and hands will also move.The fundamental task of a robotics engineer is to make it possible for robots to move in a coordinated fashion [5].If a robot does not move in such a manner,it will not be able to function well.There are two major types of movement that robots undergo,forward and reverse kinematics.Reverse Kintematics equations are easily solved by using of a series of six-by-six or four-by-four matrix transformations.Reverse kinematics can easily be seen in every day life through the movement of human arms and legs [3].The reverse kinematics problem is easily described in 3D space.Robots are built of individual components separated by a series of kinematic pairs,located at joints and axels and experiences a certain amount of allowable independent movements [6].Depending on the types of pairs present,and the number of degrees of freedom,the robot will have either a low or high range of mobility.Robotic Movement The other type of kinematic problem which arises in robotics and must be solved by engineers is that of the forward kinematic problem,described by experts as the “Mount Everest of kinematic problems” [3].While it may be an extremely difficult problem to solve,it is rather simple to explain.If a robot moves its hand to pick up an item,the robot’s shoulder and elbow move as well.While a human does not need to think about what the shoulder does while reaching for an object,the engineers must program the robot to do so.If they fail to program it correctly,the robot will be incapable of moving its arms in the proper manner.All forms of robotic movement are represented by a translation and a rotation along a single axis.This form of movement is known as screw displacement or twist [7].This form of motion can be thought of as a rotation about a fixed point and it is experienced in both robots and humans at all joints.This type of motion around a robot’s shoulders and elbows helps it to move its arm in every direction,

There are already
working age Americans that are not employed and
of the families in the entire country do not have a single member that has a job.
So what in the world are we going to do when robots start taking millions upon millions more of our jobs? Thanks to technology, the balance of power between employers and workers in this country is shifting dramatically in favor of the employers.
These days, many employers are wondering why they are dealing with so many human worker “headaches” when they can just use technology to get the same tasks done instead.
When you replace a human worker with a robot, you solve a whole bunch of problems.
Robots never take a day off, they never get tired, they never get sick, they never complain, they never show up late, they never waste time on the Internet and they always do what you tell them to do.
In addition, robotic technology has advanced to the point where it is actually cheaper to buy robots than it is to hire humans for a vast variety of different tasks.
From the standpoint of societal efficiency, this is a good thing.
But what happens when robots are able to do just about everything less expensively and more efficiently than humans can?
Where will our jobs come from?
And this is not something that is coming at some point in “the future”.
This is already happening.
According to , there will be 10,000 robots working to fulfill customer orders
warehouses by the end of ;
Amazon will be using 10,000 robots in its warehouses by the end of the year.
CEO Jeff Bezos told investors at a shareholder meeting Wednesday that he expects to significantly increase the number of robots used to fulfill customer orders.
Don’t get me wrong – I absolutely love Amazon.
And if robots can get me my stuff faster and less expensively that sounds great.
But what if everyone starts using these kinds of robots?
What will that do to warehouse jobs?
has just done a report on a new warehouse robot known as “UBR-1″.
This robot is intended to perform tasks “normally done by human workers”…
The UBR-1 is a 4-foot tall, one-armed robot that could make warehouses and factories more efficient by performing tasks normally done by human workers.
Unlike the industrial robots widely used in manufacturing today—usually large machines isolated from people for safety reasons—this robot can work alongside humans or autonomously in a workspace filled with people.
This little robot costs $50,000, and it can work all day and all night.
It just needs a battery change every once in a while.
The creators of this robot envision it performing a vast array of different tasks…
“We see the robot as doing tasks, they could be dull, they could be dirty, they could be dangerous and doing them repetitively all day in a light manufacturing environment,” said Melonee Wise, Unbounded Robotics CEO and co-founder. Those tasks include stocking shelves, picking up objects and assembling parts.
The UBR-1 isn’t designed for small component assembly, but it can manipulate objects as small as dice or a Lego piece, Wise said. Unbounded Robotics is targeting companies that want some automation to speed up their manufacturing process, but can’t afford to fully automate their businesses.
To many people this may sound very exciting.
But what if a robot like that took your job?
Would it be exciting then?
Of course you can’t outlaw robots.
And you can’t force companies to hire human workers.
But we could potentially have major problems in our society as jobs at the low end of the wage scale quickly disappear.
According to , restaurants all over the nation are going to automated service, and a recent University of Oxford study concluded that there is a 92 percent chance that most fast food jobs will be automated in the coming years…
Panera Bread is the latest chain to introduce automated service, announcing last month that it plans to bring self-service ordering kiosks as well as a mobile ordering option to all its locations within the next three years. The news follows moves from Chili’s and Applebee’s to place tablets on their tables, allowing diners to order and pay without interacting with human wait staff at all.
Panera, which spent $42 million developing its new system, claims it isn’t planning any job cuts as a result of the technology, but some analysts see this kind of shift as unavoidable for the industry.
In a widely cited paper released last year, University of Oxford researchers estimated that there is a 92% chance that fast-food preparation and serving will be automated in the coming decades.
It is being projected that other types of jobs …
Delivery drivers could be replaced en masse by , which are likely to hit the market within a decade or two, or even drones. In food preparation, there are start-ups offering robots for
and . A food processing company in Spain now uses robots to inspect heads of lettuce on a conveyor belt, throwing out those that don’t meet company standards, the Oxford researchers report.
Could you imagine such a world?
When self-driving vehicles take over, what will happen to the
that drive trucks for a living?
Our planet is changing at a pace that is almost inconceivable.
Over the past decade, the big threat to our jobs has been workers on the other side of the globe that live in countries where it is legal to pay slave labor wages.
But now even those workers are having their jobs taken away by robots.
For example, just check out what is happening …
to replace human workers and it looks like that change, albeit gradual, is about to start.
The company is allegedly paying $25,000 per robot – about three times a worker’s average salary – and they will replace humans in assembly tasks. The plans have been in place for a while – I spoke to
– and it makes perfect sense. Humans are messy, they want more money, and having a half-a-million of them in one factory is a recipe for unrest. But what happens after the halls are clear of careful young men and women and instead full of whirring robots?
Perhaps you think that your job could never be affected because you do something that requires a “human touch” like caring for the elderly.
Well, according to , robots are moving into that arena as well…
Imagine you’re 85, and living alone. Your children are halfway across the country, and you’re widowed. You have a live-in aide – but it’s not human. Your personal robot reminds you to take your medicine, monitors your diet and exercise, plays games with you, and even helps you connect with family members on the Internet.
And robots are even threatening extremely skilled professions such as doctors.
For instance, just check out this excerpt from a Bloomberg article entitled ““…
Johnson & Johnson
anesthesiologists during simple procedures such as colonoscopies — not with nurse practitioners, but with machines. Sedasys, which dispenses propofol and monitors a patient automatically, was recently approved for use in healthy adult patients who have no particular risk of complications. Johnson & Johnson will lease the machines to doctor’s offices for $150 per procedure — cleverly set well below the $600 to $2,000 that anesthesiologists usually charge.
And this is just the beginning.
In a , I discussed the
by Dr. Carl Frey and Dr. Michael Osborne of Oxford University which came to the conclusion that 47 percent of all U.S. jobs could be automated within the next 20 years.
47 percent?
That is crazy.
What will the middle class do as their jobs are taken away?
The world that we live in is becoming a radically different place than the one that we grew up in.
The robots are coming, and they are going to take millions of our jobs.
So what do you think of this robot invasion?

Performing Networking Tasks
Updated: October 17, 2013Applies To: Windows PowerShell 2.0, Windows PowerShell 3.0, Windows PowerShell 4.0, Windows PowerShell 5.0
Because TCP/IP is the most commonly used network protocol, most low-level network protocol administration tasks involve TCP/IP. In this section, we use Windows PowerShell and WMI to do these tasks.
To get all IP addresses in use on the local computer, use the following command:
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter IPEnabled=TRUE -ComputerName . | Format-Table -Property IPAddress
The output of this command differs from most property lists, because values are enclosed in braces:
{192.168.1.80}
{192.168.148.1}
{192.168.171.1}
To understand why the braces appear, use the Get-Member cmdlet to examine the IPAddress property:
PS& Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter IPEnabled=TRUE -ComputerName . | Get-Member -Name IPAddress
TypeName: System.Management.ManagementObject#root\cimv2\Win32_NetworkAdapter
Configuration
MemberType Definition
---------- ----------
IPAddress Property
System.String[] IPAddress {}
The IPAddress property for each network adapter is actually an array. The braces in the definition indicate that IPAddress is not a System.String value, but an array of System.String values.
To display detailed IP configuration data for each network adapter, use the following command:
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter IPEnabled=TRUE -ComputerName .
The default display for the network adapter configuration object is a very reduced set of the available information. For in-depth inspection and troubleshooting, use Select-Object or a formatting cmdlet, such as Format-List, to specify the properties to be displayed.
If you are not interested in IPX or WINS properties—probably the case in a modern TCP/IP network—you can use the ExcludeProperty parameter of Select-Object to hide properties with names that begin with "WINS" or "IPX:"
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter IPEnabled=TRUE -ComputerName . | Select-Object -Property [a-z]* -ExcludeProperty IPX*,WINS*
This command returns detailed information about DHCP, DNS, routing, and other minor IP configuration properties.
You can perform a simple ping against a computer using by Win32_PingStatus. The following command performs the ping, but returns lengthy output:
Get-WmiObject -Class Win32_PingStatus -Filter "Address='127.0.0.1'" -ComputerName .
A more useful form for summary information a display of the Address, ResponseTime, and StatusCode properties, as generated by the following command. The Autosize parameter of Format-Table resizes the table columns so that they display properly in Windows PowerShell.
PS& Get-WmiObject -Class Win32_PingStatus -Filter "Address='127.0.0.1'" -ComputerName . | Format-Table -Property Address,ResponseTime,StatusCode -Autosize
ResponseTime StatusCode
------------ ----------
A status code of 0 indicates a successful ping.
You can use an array to ping multiple computers with a single command. Because there is more than one address, use the ForEach-Object to ping each address separately:
"127.0.0.1","localhost","" | ForEach-Object -Process {Get-WmiObject -Class Win32_PingStatus -Filter ("Address='" + $_ + "'") -ComputerName .} | Select-Object -Property Address,ResponseTime,StatusCode
You can use the same command format to ping all of the computers on a subnet, such as a private network that uses network number 192.168.1.0 and a standard Class C subnet mask (255.255.255.0)., Only addresses in the range of 192.168.1.1 through 192.168.1.254 are legitimate local addresses (0 is always reserved for the network number and 255 is a subnet broadcast address).
To represent an array of the numbers from 1 through 254 in Windows PowerShell, use the statement 1..254. A complete subnet ping can be performed by generating the array and then adding the values onto a partial address in the ping statement:
1..254| ForEach-Object -Process {Get-WmiObject -Class Win32_PingStatus -Filter ("Address='192.168.1." + $_ + "'") -ComputerName .} | Select-Object -Property Address,ResponseTime,StatusCode
Note that this technique for generating a range of addresses can be used elsewhere as well. You can generate a complete set of addresses in this way:
$ips = 1..254 | ForEach-Object -Process {"192.168.1." + $_}
Earlier in this user's guide, we mentioned that you could retrieve general configuration properties by using Win32_NetworkAdapterConfiguration. Although not strictly TCP/IP information, network adapter information such as MAC addresses and adapter types can be useful for understanding what is going on with a computer. To get a summary of this information, use the following command:
Get-WmiObject -Class Win32_NetworkAdapter -ComputerName .
To assign the DNS domain for automatic name resolution, use the Win32_NetworkAdapterConfiguration SetDNSDomain method. Because you assign the DNS domain for each network adapter configuration independently, you need to use a ForEach-Object statement to assign the domain to each adapter:
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter IPEnabled=true -ComputerName . | ForEach-Object -Process { $_. SetDNSDomain("") }
The filtering statement "IPEnabled=true" is necessary, because even on a network that uses only TCP/IP, several of the network adapter configurations on a computer are not true TCP/IP they are general software elements supporting RAS, PPTP, QoS, and other services for all adapters and thus do not have an address of their own.
You can filter the command by using the Where-Object cmdlet, instead of using the Get-WmiObject filter.
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -ComputerName . | Where-Object -FilterScript {$_.IPEnabled} | ForEach-Object -Process {$_.SetDNSDomain("")}
Modifying DHCP details involves working with a set of network adapters, just as the DNS configuration does. There are several distinct actions you can perform by using WMI, and we will step through a few of the common ones.
To find the DHCP-enabled adapters on a computer, use the following command:
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter "DHCPEnabled=true" -ComputerName .
To exclude adapters with IP configuration problems, you can retrieve only IP-enabled adapters:
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter "IPEnabled=true and DHCPEnabled=true" -ComputerName .
Because DHCP-related properties for an adapter generally begin with "DHCP," you can use the Property parameter of Format-Table to display only those properties:
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter "DHCPEnabled=true" -ComputerName . | Format-Table -Property DHCP*
To enable DHCP on all adapters, use the following command:
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter IPEnabled=true -ComputerName . | ForEach-Object -Process {$_.EnableDHCP()}
You can use the Filter statement "IPEnabled=true and DHCPEnabled=false" to avoid enabling DHCP where it is already enabled, but omitting this step will not cause errors.
The Win32_NetworkAdapterConfiguration class has ReleaseDHCPLease and RenewDHCPLease methods. Both are used in the same way. In general, use these methods if you only need to release or renew addresses for an adapter on a specific subnet. The easiest way to filter adapters on a subnet is to choose only the adapter configurations that use the gateway for that subnet. For example, the following command releases all DHCP leases on adapters on the local computer that are obtaining DHCP leases from 192.168.1.254:
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter "IPEnabled=true and DHCPEnabled=true" -ComputerName . | Where-Object -FilterScript {$_.DHCPServer -contains "192.168.1.254"} | ForEach-Object -Process {$_.ReleaseDHCPLease()}
The only change for renewing a DHCP lease is to use the RenewDHCPLease method instead of the ReleaseDHCPLease method:
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter "IPEnabled=true and DHCPEnabled=true" -ComputerName . | Where-Object -FilterScript {$_.DHCPServer -contains "192.168.1.254"} | ForEach-Object -Process {$_.ReleaseDHCPLease()}
When using these methods on a remote computer, be aware that you can lose access to the remote system if you are connected to it through the adapter with the released or renewed lease.
You can perform global DHCP address releases or renewals on all adapters by using the Win32_NetworkAdapterConfiguration methods, ReleaseDHCPLeaseAll and RenewDHCPLeaseAll. However, the command must apply to the WMI class, rather than a particular adapter, because releasing and renewing leases globally is performed on the class, not on a specific adapter.
You can get a reference to a WMI class, instead of class instances, by listing all WMI classes and then selecting only the desired class by name. For example, the following command returns the Win32_NetworkAdapterConfiguration class:
Get-WmiObject -List | Where-Object -FilterScript {$_.Name -eq "Win32_NetworkAdapterConfiguration"}
You can treat the entire command as the class and then invoke the ReleaseDHCPAdapterLease method on it. In the following command, the parentheses surrounding the Get-WmiObject and Where-Object pipeline elements direct Windows PowerShell to evaluate them first:
( Get-WmiObject -List | Where-Object -FilterScript {$_.Name -eq "Win32_NetworkAdapterConfiguration"} ).ReleaseDHCPLeaseAll()
You can use the same command format to invoke the RenewDHCPLeaseAll method:
( Get-WmiObject -List | Where-Object -FilterScript {$_.Name -eq "Win32_NetworkAdapterConfiguration"} ).RenewDHCPLeaseAll()
To create a network share, use the Win32_Share Create method:
(Get-WmiObject -List -ComputerName . | Where-Object -FilterScript {$_.Name -eq "Win32_Share"}).Create("C:\temp","TempShare",0,25,"test share of the temp folder")
You can also create the share by using net share in Windows PowerShell:
net share tempshare=c:\temp /users:25 /remark:"test share of the temp folder"
You can remove a network share with Win32_Share, but the process is slightly different from creating a share, because you need to retrieve the specific share to be removed, rather than the Win32_Share class. The following statement deletes the share "TempShare":
(Get-WmiObject -Class Win32_Share -ComputerName . -Filter "Name='TempShare'").Delete()
Net share works as well:
PS& net share tempshare /delete
tempshare was deleted successfully.
The New-PSDrive cmdlets creates a Windows PowerShell drive, but drives created this way are available only to Windows PowerShell. To create a new networked drive, you can use the WScript.Network COM object. The following command maps the share \\FPS01\users to local drive B:
(New-Object -ComObject WScript.Network).MapNetworkDrive("B:", "\\FPS01\users")
The net use command works as well:
net use B: \\FPS01\users
Drives mapped with either WScript.Network or net use are immediately available to Windows PowerShell.
