beefsack writes "An engineer by the name of Andrej Skraba has combined an Arduino board and an MK802 mini PC running Ubuntu to create a robot which is controllable via its own node.js server and a mobile phone. Seen by some as products competing in a similar space, Andrej shows how the two devices can make the most of their unique features to complement each other, working together."

Seems that the route to novelty and ingenuity these days requires you somehow cable a cell phone into your project.
Even when your computer-on-stick already has Wifi built in.

It could have been worse - this could have been another tiresome Raspberry Pi ("the cheap crap computer money can't buy") story.

True. But instead we get another tiresome robot this-or-that story.

Yeah. I'm tired of living in the future.

I for one welcome our tiresome robot this-or-thats overlords.... provided they are well-armed and use their offensive capabilities to eliminate Slashdot editors.

I fail to see how this is even remotely newsworthy. My undergraduate EECS projects were far more advanced than this.

OK, so this guy has a dumb battery, motors, wheels platform, with no sensors. On this, he put a web server with WiFi, which he then controls from a cell phone. So all that this does is run two small DC motors under manual remote control.

This is lame even by amateur robotics standards today. There's enough compute power there for a full vision system. Running Apache and node.js is not useful. It might be worthwhile to get familiar with the technology, but you don't publicize it.

Let me see your finished product and I will judge it for you. Sniping at somebody who might be an amateur roboticist and possibly wrote his first Java script is easy. Putting this into being isn't. Wanker.

Its Especially Easy, and certainly fair game when that person posts his first juvenile project on Youtube, then the maker of the computer SOC submits it to slashdot claiming its from an ENGINEER.

Hypocrite.

Not to mention that you can buy Android/iPhone based drones that send video back to the phone today, which essentially does everything here and then a bunch more. That can be had for $299.

But here is the difference - this is running Ubuntu! [/sarcasm]

He was nice enough to include subtitles and point out each component. Most of the amateur showoff videos I've seen are full of random music (so you can't actually hear the robot), don't bother to explain anything, and sometimes go out of their way to make sure you can't tell if they're running in real-time or not. In that respect, this wasn't bad. Though I agree, running Ubuntu and Apache for a few simple commands is a complete waste of processing power.

From Slashdot summary:

Seen by some as products competing in a similar space, Andrej shows how the two devices can make the most of their unique features to complement each other [while] working together.

No it didn't. Please stop lying.

The story was submitted by the someone associated with Miniand, the maker of the computer. This poor guy probably never dreamed it would end up on Slashdot. A blatant advertising ploy.

Wow, John. Given some of your achievements I'd think you of all people would be supportive of people's technical projects big and small. Now if you were criticising Slashdot's decision to front page this...

Re:Pointless (1)

jerdnaabarks (2800649) | about a year and a half ago | (#42372069)

Main thing is that combination of Arduino and MK802 removes the need for the cable as seen in this case: http://youtu.be/jf-cEB3U2UQ#t=11m28s [youtu.be] And yes, by shown example all the computing power for machine vision etc. is now on board. Not to mention node.js javascript and firmata. Your observation about new computing power on board which becomes available is right. Lame? ... I'm sorry to hear that.

"its" is the possessive form.

Yes, and we all know this. However, we're just very complex sentient chemical reactions and thus we're prone to make mistakes. In fact one of the strengths of having such a large, inefficient pattern matching mind with many redundant information processing channels is that when said mistakes occur you can identify them and understand what the other communicator means -- Many time such errors are missed in the proof reading because the writer knows what they meant, and reads it as such, not because they can't follow the current iteration of the language's changing grammatic rules. Cyberneticists dream to one day achieve the level of comprehension that you now squander by balking at minor syntax errors like a dumb BASIC interpretor.

BUT, consider: (-1)

Anonymous Coward | about a year and a half ago | (#42371409)

1. No known species of reindeer can fly. BUT there are 300,000 species of living organisms yet to be classified, and while most of these are insects and germs, this does not COMPLETELY rule out flying reindeer which only Santa has ever seen.

2. There are 2 billion children (persons under 18) in the world. BUT since Santa doesn't (appear) to handle the Muslim, Hindu, Nigger, Jewish and Buddhist children, that reduces the workload to 15% of the total - 378 million according to the Population Reference Bureau. At an average (census rate of 3.5 children per household, that's 91.8 million homes. One presumes there's at least one good child in each.

3. Santa has 31 hours of Christmas to work with, thanks to the different time zones and the rotation of the earth, and assuming he travels east to west (which seems logical). This works out to 822.6 visits per second. This is to say that for each Christian household with good children, Santa has 1/1000th of a second to park, hop out of his sleigh, jump down the chimneys, fill the stockings, distribute the remaining presents under the tree, eat whatever snacks have been left, get back up the chimney, get back into the sleigh and move on to the next house. Assuming that each of these 91.8 million stops are evenly distributed around the earth (which, of course we know to be false but for the purpose of our calculations we will accept), we are now talking about .78 miles per household, a total trip of 75.5 million miles, not counting stops to do what most of us must do at least once every 31 hours, plus feeding and etc. This means that Santa's sleigh is moving at 650 miles per second, 3000 times the speed of sound. For purposes of comparison, the fastest man-made vehicle on earth, the Ulysses space probe, moves at a poky 27.4 miles per second - a conventional reindeer can run, tops, 15 miles per hour.

4. The payload on the sleigh adds another interesting element. Assuming that each child gets nothing more than a medium-sized Lego set (2 pounds), the sleigh is carrying 321,300 tons, not counting Santa, who is invariably described as overweight. On land, conventional reindeer can pull no more than 300 pounds. Even granting that "flying reindeer" (refer to point #1) could pull TEN TIMES the normal load, we cannot do the job with eight, or even nine. We need 214,200 reindeer. This increases the payload - not even counting the weight of the sleigh - 353,430 tons. Again, for comparison - this is four times the weight of Queen Elizabeth.

5. 353,000 tons traveling at 650 miles per second creates enormous air resistance - this will heat the reindeer up in the same fashion as spacecrafts re-entering the earth's atmosphere. The lead pair of reindeer will absorb 14.3 QUINTILLION joules of energy per SECOND, EACH! In short, they will burst into flames almost instantaneously, exposing the reindeer behind them, and create a deafening sonic boom in their wake. The entire reindeer team will be vaporized within 4.26 thousandths of a second. Santa, meanwhile, will be subjected to centrifugal* forces 17,500.06 times greater than gravity. A 250 pound Santa (which seems ludicrously slim) would be pinned to the back of his sleigh by 4,315,015 pounds of force.

In conclusion - If Santa ever DID deliver presents on Christmas Eve, he's dead by now. And he'd be a faggot.

======================
*Please note that centrifugal is a made-up non existent word. The real word should be centripetal. Centrifugal is a made up force that physics people HATE! So please, everyone use the world centripetal, not centrifugal. Thanks!

Specifically he sells the MK803 Android Mini PC: https://www.miniand.com/

Good attempt but not really worthy of a slashdot post...

This robot does illustrate the need for a common cabling standard for robotics.

Yep, not worthy!

Re:Beefsack is a business (0)

Anonymous Coward | about a year and a half ago | (#42377355)

Interesting the MK803 isn't that common, The mk802 is very popular and is being superceded by the mk808. These things are getting very powerful.

Not a Robot! (0)

Please, please, remember this: it's NOT a ROBOT unless it drives by himself! This is just an expensive android controlled, half a meter high, rc car.

Please stop supporting them! (-1)

Anonymous Coward | about a year and a half ago | (#42371633)

"Makers" are parasites that cling onto geek culture and suck the life right out of it. Arduino? It's a child's toy. The maker "culture" is subversive and shouldn't be supported or disseminated on /.

We have been selling these since 2010 (-1)

Anonymous Coward | about a year and a half ago | (#42372155)

www.robots-everywhere.com recently we even set one up to semiautonomously deposit our checks at the local bank. Why is this news?

Sounds like FPS Russian! (1)

The narrator's voice totally sounds like the FPS Russian's [youtube.com] voice. Now I want an Arduino controlled 50-cal machine gun with explosive rounds!

Root Kit it for fun (1)

epSos-de (2741969) | about a year and a half ago | (#42374027)

You can control it randomly too. The robot is controlled by address calls.

212.235.232.101:8080/1/100/1 - forward
212.235.232.101:8080/2/100/1 - stop
212.235.232.101:8080/3/100/1 - backward

100 is a parameter of speed of DC motor, it could go from 0 to 255.

Have fun messing around !
