Scientists demonstrate a 5 ½ foot laser guided robot powered by a Mac mini

  
Scientists recently demonstrated a laser-guided robot, dubbed the EL-E, which is able to grab items that users point at with a laser pointer. Developed by scientists from Georgia Tech and Emory universities, the EL-E has the possibility of many useful applications, such as replacing service animals and helping patients with degenerative disease.

The EL-E, which is powered by a single Mac mini that sits at its base, stands at 5 ½ feet tall. Its exterior is dominated by sensors, lasers and cameras -- all of which help the robot work and find the item that has been targeted by the user.  

To work the robot, users are required to simply point a laser at an object for a few seconds. To confirm the robot has received the command, it emits a beep and proceeds to move to the object, rolling towards it using its three wheels. Once it is in range, the mechanical arm of the robot grabs the item, and when the user points the laser at his or her foot, it moves back to the user. The robot then searches for a human face before offering the item. According to researchers working on the robot, the EL-E has a 90% success rate.  

Talking to the Associated Press, Charlie Kemp, director of Georgia Tech's Center for Healthcare Robotics and the EL-E's designer, says that the robot “creates a clickable world. The entire world becomes a point and click interface. Objects become buttons. And if you point at one, the robot comes to grab it."

The robot is still in the early stages of its development. Its mechanical crane can only lift a maximum of 1.2 pounds. Researchers are optimistic about the possibilities the robot holds. They envision a future where the EL-E will one day be able to open doors, turn off light switches, and guide patients through the halls.  

In designing the robot, the design team wants to change the conventional rules for robots. Kemp believes that many times the primary focus of engineers is to make a robot act like a human. However, in pursuit of making the robot more like a human, the engineers end up not looking at other avenues through which robots can interact with people.

Researchers plan to test the robot in a real-world environment this summer with patients who have degenerative diseases. The cost of constructing the robot has not been disclosed.

Why is this even news?

Wow, macs are so friggin hard to program, that it is news that they got a mac mini to even do this. Let's see, there are hundreds, if not thousands of hardware and software packages that run on x86 that do this already, or give you an existing base to program with, yet some idiot uses a mac and it is an amazing thing. It probably could have been done in a tenth the time and a quarter of the cost.

The reason this is using a Mac is that to use a comparable PC costs MORE. Macs of this size and weight are cheaper than PCs of this size and weight.

This is supposed to be a mobile robot.

Really? Because I had always noticed that Mac's are ~40% more than typical PC's. You don't need a full fledged PC to run this thing. A small amount of memory and a processor will do the trick just fine.

A mobile robot needs a small and lightweight PC. The Mac mini is only 2.9 pounds, 6.5" by 6.5" by 2", and $599.

Similar PCs with those weight and dimensions cost about $1k

It's not about the compute ability, it's about the size and weight!

If you can build a sophisticated robot that does this then you don't need to buy a retail PC. All you need is a processor and some memory.

If you're smart enough to build a robot, I think you're smart enough to do a cost-benefit analysis of designing your own control board, OS, and peripherals, vs using a pre-built and predesigned system.

For whatever reason, they decided it was either cheaper, faster, or easier to use a Mac mini than to design something from scratch. It probably gave them more time/resources to actually build and program the robot.

I'm guessing you have never built your own pc before.
http://www.newegg.com/Product/Product.aspx?Item=N8... <-- you can add Ram, CD-Rom, HD, and PSU for less then $400 and you've got yourself a mac mini equal that you can put in any case you want. + it runs windows without having to use any special software

What is so hard to understand about "weight and dimensions?"

Show me the case that it would go in that's the same as a Mac Mini, and don't forget the Mini has a Core 2 Duo and not Via C7.

The number of Mini-ITX platforms available for Windows is huge (or. . .tiny. . .awww, I crack myself up)

Tiny and inexpensive computers is not the domain of Mac. . .it's been the domain of the Windows home-brewer for years. Let's see - a computer in the Millenium Falcon, a clock, whatever.

And you don't need a Core 2 Duo for a robot. NO way. NO how.

I think you underestimate 3d and face visualization if you think it doesn't need a Core 2 Duo...

This robot has to navigate in three dimensions as well as perform "grasping" actions, then return to the person, look for a face, and offer the object.

Well seeing as the mac mini has it's own special case, and these guys ARE robot scientists, the fact that it's not in a case is actually better because now they can move the parts and place them in different areas of the robot rather then one central location. Or they could even make their own case to match the robot better. In my opinion those are two good reasons for not using the mac mini.

An Intel D201GLY/2, Via Mini/Nano/Pico-ITX or AOpen mini PC should all work and be cheaper.

Mini-ITX is 17cm x 17cm, so bigger, but I would think still doable. Just need to incorporate a custom case into the base of the design. The Intel boards are strictly speaking Micro-ATX since they are 17.1cm.

The AOpen PC's are about the same size as the Mac and Pico-ITX is only something like 10cm X 7cm, so much smaller. Nano-ITX from recollection is 12cm x 12cm.

Really if you don't need a really powerful CPU, then a Via passive embedded solution would be better. At least until Intel's new stuff comes out.

An AOpen miniPC with Core 2 Duo support from buy.com costs $340 sans CPU, memory, and harddrive. Just adding a 2.0GHz CPU pushes the price up to $600, without RAM or HDD.

A comparable Mac mini only costs $600 and it comes with OS, HDD, wireless networking, RAM, and CPU.

2.0GHz (T7200) Mac Mini with 1GB RAM = $1080AUD
AOpen = $480
T7300 = $300
That leaves $300 for a slow 2.5" HD and 1GB of RAM. The Aopen has the newer GM965 chipset though with faster FSB, so faster RAM and the newer T7300 instead of T7200.

OS is free, unless you want Windows. The wireless kit is $60, although you could probably use a 3rd party card and get 802.11n (the mac is only g anyway).

160GB 2.5" 5400 HDD = $80
1GB SO DDR2 = $26

So $480+300+60+80+26 = $946
So, I guess not that much cheaper, but still cheaper, also faster RAM (800 vs 667), newer chipset and CPU. You could go a 945 like the Mac, but then socket M CPU's are more than socket P.

Personally I would still be going with a Mini-ITX solution and a custom case though and for those bashing the Via C7, that really depends on the power required and you can mini-ITX boards that take Core 2's and AMD X2's anyway.

Possible that Apple gave them the Mac Mini, in which case price really doesn't come into it.

Also $812.17 @ buy.com for a T7200 based Mac Mini. Slightly more than your quoted $600.

now that you mention it, it would make quite a bit of sense for apple to simply give them the computer in exchange for media coverage. If you have ever visited the apple site, they always have a list of the latest articles involving mac's, so They've probably put this article there as well.

Except of course we are using US prices since these researchers are in the US.

$799 for the 2GHz Mac mini.

Yes, this is news. Mac's are much easier to program than PC's. I develop for PC's (.Net and VB), Java, and Mac. Apple has a wealth of frameworks 1st developed at NeXT and with added frameworks all the time. One line of Apple code = 100's of lines of windows/java code. Don't believe it, then become a Mac developer you'll understand, if you have the capacity for such things. I don't care how many windows developers are out there, because like in baseball there only a few A-ROD/Jeters. Oh one more thing - isn't creating a robot a being a bit creative? Yep, though so, Mac people are creative.

ignoring all glaring typo's, you are making that assumption based on faulty logic. if a, then b. if someone makes a robot using a mac as the computer, then all macintosh users are creative? Does anyone see a problem with that?

In this case, thanks goodness it's Apple powered. If a left click is a grab, imagine what a right click might have been?
