A robot built to play Towers of Hanoi on an iPhone. I believe that this robot execute moves faster than any human can. For more information, visit http://tzywen.com/modules.php?name=News&file=article&sid=568

  • That is absolutely CRAZY!!! How many rings can you play with on the iPhone? Is there a limit?

  • 8 rings is the limit.

  • That's really cool. Did you build and/or program the robot?

  • yes, I built and programmed it. you can find out more about it on the link under "more info"

  • Quick question. My iPhone doesn't detect anything BUT human fingers. I've tried using a lot of things (pencils, wallets, paper), but none of it would work.

    How did the iPhone detect the robots wires?

  • the iphone's screen is based on capacitive touch technology. so when the wires touched the drops of water on the screen, the charges on the screen is discharged, simulating the discharging of the charges through human fingers.

  • I found this dificult to mastrubate to.

  • wow, its like a physical version of a too-assisted speedrun.

  • elegante pero que se detenga cuando acaba ps jajaja

  • Doesn't that hurt the screen at all?

  • I can sure you, the fastest ToH player is an application ;)

    Nice try btw. :)

  • its really easy. the formula is this:

    If the whole tower you want to move has an even number of pieces, your first move has to be to the side different than the one where you want it to end. If its an odd number, put your first piece on the side where the whole tower is going to end. repeat this proces with smaller towers until you get to the desired position

  • any faster and i doubt the game could keep up WITH the robot.

  • usually sticks dont work with the touch screen how did you get that stick to work?

    fastest I got 7 (with real wood which takes longer than an iphone i also have it on my ipod touch) was like 20 min. Gosh these things are HARD! :P

  • if the app had its own mind it'd be wondering what the hell's wrong with this kid?

  • its classic recurrsion

    it works like this

    directions for (moving n disks from tower A to C using B)

    if n is 1, move from A to C

    otherwise

    follow the directions (for moving n-1 disks from tower A to tower B using C)

    move disk from A to C

    follow the directions (for moving n-1 disks from tower B to tower C using A)

    this might be confusing and i would explain it better...but its really hard to teach this concept in 500 char. so look up towers of hanoi on wikipedia and gl
