Powered Exoskeletons

hulc-testing-1

As some readers will know, I have a great interest in prosthetics and other aids that help people to overcome barriers due to their being in some way different. Recently I wrote articles about prosthetic limbs, interviewed the World record holding runner Martina Caironi and looked at canes for the blind. Many posts ago I looked at elective amputation, and today I would like to cast my gaze over exoskeletons.

Companies have now started to produce powered exoskeletons in various forms, for both military and civilian use. Dual use technology has also always been of interest to me for some time, as it is difficult to see how we could draw a line between civilian use and development and military use. If we think that most robot limb and hand developments are geared towards treating soldiers who have been injured while on active service, then we see why the military is the largest investor in such research.

If we take the powered exoskeleton the link is more obvious. The military want an armoured exoskeleton that supports itself (so the soldier does not have to carry the weight) that can enable said soldier to carry more ammunition and supplies, heavier weaponry and move quicker and for a longer period of time.

Robocop comes to mind. But one thing is for sure, the FDA recently gave approval for the sales of the first exoskeleton in the USA, and you can also get one if you live in Europe or parts of the Middle East (at a cost of about $65,000), and so they will soon be seen on the streets.

And there are also many applications in hospital. The machines are used to get people walking again who have had accidents, to build up muscle and to aid other forms of rehab such as balance loss. Who could say that technology that allows someone to walk again after years in a wheelchair is a bad thing?

Exoskeleton in Medical Use

Exoskeleton in Medical Use

 

Well there are actually some arguments related to this. Many of the following are taken from an article called Exoskeletons in a disabilities context: the need for social and ethical research , written by Jathan Sadowski of Arizona State University and available here (payment required).

One problem is that creating the model of how it is correct to move and “be”, makes the non acceptability of alternatives worse. To give an example, the more technology works towards making us all walk upright, as many humans do, the more those who do not walk upright become marginalized. Society does not change to incorporate the differences, but moves to “rectify” the differences, as if it was just a problem to be solved. This may not be the right approach. This wonderful article by Jenny Davis explains all.

Another possible problem is dependence. If a person has access to such a machine they may grow to be dependent upon it. What happens if they lose the use of the machine? If they can no longer afford it, or it is withdrawn, or breaks down? With dependency comes withdrawal, and we might imagine that it would be serious cold turkey in this case. And all this comes without mention of the problem of availability to all. These systems are not cheap.

There are many industrial applications that relate to the needs for the soldiers above, allowing workers to carry heavy objects for long periods of time, or use heavier machinery, something that could on the surface be seen as little more than an advancement in industrialized production methods. This kind of technology would be fantastic for disaster workers too, as well as fire fighters and people working in remote areas or difficult to access spaces.

Here are a couple of links that you might be interested in. This Forbes video shows the development of a new military exoskeleton, once more explaining its civilian use. This TED talk is a little older, showing the development of the same project. Neither has any critical view of the technology however, and the TED talk almost looks like publicity.

In some of the cases above the use of this technology could undoubtedly be described as human enhancement. In others some would say that it is something more akin to a mechanical wheelchair that improves mobility. But one thing is for sure, as Sadowski point out in the article cited above, “any serious consideration – whether critique, condemnation, or support – of enhancement technologies must also incorporate critical inquiry about ethics, politics, justice, and social relations”.

Car Trouble

car loans

Last week the New York Times ran an interesting article about cars fitted with the so-called starter interrupt device.

Many might know that some cars have an engine cut off switch that can be remotely operated. If someone steals your car you might be able to track it and turn the engine off if you have forward thinkingly fitted one. But they are becoming more commonly used today on cars that are sold with lease or debt payment.

And it is extremely simple, I sell you the car and as long as you repay the debt or lease charges the vehicle is yours to do what you will, and drive where you like. But if you miss a payment, I can remotely track your movement and at the moment I see fit I can block the car.

So one morning, you have not made the payment on Friday because you are on holiday, you go out to take your child to school, or the dentist, or the hospital because she is sick, and the car won’t start.

Now I would agree that if you want a car you should pay for it, and that if you don’t keep up payments you may lose it, but there are other knock on effects to using such technology in this way. Of course there is the problem that you might block a car that would be used in an emergency situation, like the one suggested above. But the effect of having such a ready resource in reclaiming the car may lead you to sell it to someone who might have difficulty repaying the loan. If you knew that you might have to first find the car, send a car transporter out to recover it and incur some time and financial interference, you might think twice about selling it to someone with a bad credit rating and precarious situation.

If you know you can just track the car, block it when it is in a good place for you to collect, and always know where it is, then who cares? Give them the car and get it back later.

These devices are currently fitted on about 2 million cars, and the article states that their use is helping to push the use of sub-prime auto loans. I am no financial guru but I have heard a lot of talk and read a lot about sub-prime mortgages, and they don’t get good press.

So even if we put aside the issue of privacy, as the lender can see your every move (I put it aside because if you carry a mobile phone you are in the same boat), there is the problem of physical security in case of malfunction, data protection and of course dragging people into high rate loans and all the associated black market dealings that go with debt. But we should not forget that this technology also means that people who would not be able to buy a car can get hold of one, and people might accept the device if the choice is that of car with device, or no car.

High rate loans are justified because they are high risk, so I might argue that if you take the risk out of the loan then the rate should drop, this does not however seem to be the case (surprisingly).

Read more on the argument through the link to the New York Times above, and let me know in the comments section if you have any experience.

Tor, An Ethical Dilema

tor

Over the summer I have been following reporting surrounding the TOR project. I have learnt some interesting things. I must admit that I tried to download the browser but I couldn’t work out how to get it up and running, but that is probably more due to my own incompetence than anything else.

Tor has some serious issues as far as ethics goes, because it is designed to help people to remain anonymous as they use the net. This may to some seem perfectly justified given that Google and their friends are monitoring our every move and storing it all for resale later, but it is also great for criminal activity.

Recently reports emerged from Russia that the head of the Federal Security Service (FSB) has personally ordered preparations for laws that would block the Tor anonymity network from the entire Russian sector of the Internet. Obviously his aim is not to stop people from anonymously using the Internet, but to fight crime. The agency initiated the move as internet anonymizers were used by weapon traffickers, drug dealers and credit card fraudsters, giving the FSB an obvious interest in limiting the use of such software.

Other reports claim that not all of Russian law enforcement are in agreement, because criminals tend to overestimate the protection provided by the Undernet, act recklessly and allow themselves to get caught. Here the so-called Undernet is the key though, as anonymity is difficult to police.

Other reports state that “Security experts have accused US law enforcement of taking advantage of a flaw in the Firefox Internet browser then exploiting it to identify and potentially monitor subscribers to Tor”. It appears that the malware comes from the USA, but nobody is admitting to creating it, and as the Russians accuse the FBI and vice versa, any truth will be difficult to find.

One truth is however that Tor allows for the proliferation of various forms of criminality and exploitation that I would rather not go into here. The problem remains though, do we have the right to online anonymity? If not who has the right to stop us?

To return to following the news, I read that workers at the NSA and GCHQ in the UK have been accused of leaking information that they have regarding flaws in the workings of Tor. These two organizations are extremely interested in the browser for the obvious reasons above, but there is more that you might expect here. According to the BBC “The BBC understands, however, that GCHQ does attempt to monitor a range of anonymisation services in order to identify and track down suspects involved in…….crimes”.

But! Tor was originally designed by the US Naval Research Laboratory, and continues to receive funding from the US State Department. It is used by the military, activists, businesses and others to keep communications confidential and aid free speech.

And it turns out that the investigating agency rely on Tor for their own work, to keep themselves safe and anonymous, so they seem to be in a bit of a contradictory position to say the least.

So there appear to be many unanswered questions about the level of anonymity achieved, who has access, who works to destroy and who works to aid the project, and once more I find myself looking into a murky world.
