Arduino and MK802 Robot, Controlled By Phone
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.
Sig Battery depleted. Reverting to safe mode.
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.
I thought in Soviet Russia, robot control you!
"it's" means "it is"
"its" is the possessive form.
Ugh.
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!

Good attempt but not really worthy of a slashdot post...
This robot does illustrate the need for a common cabling standard for robotics.
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.
"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 /.
www.robots-everywhere.com recently we even set one up to semiautonomously deposit our checks at the local bank. Why is this news?
The narrator's voice totally sounds like the FPS Russian's voice. Now I want an Arduino controlled 50-cal machine gun with explosive rounds!
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 !
