Brute-force safe-cracking bot
posted February 2 2011 7:13.46 by Giorgos Lazaridis

Traditional safes have many protection layers against thieves. Two very curious MIT students made an automatic dialer that is possible to open a safe. The method is simple: Brute-force the combination, which means that the bot dials "random" codes, until the correct one is found. It is designed to crack the combination on a Sargent and Greenleaf 8500 lock. The code entering system is as follows: First, turns the dial 4 revolutions to the first number, then three revolutions to the second and then two revolutions to the final number. Then, one revolution to zero, press the dial inwards and finally rotate the dial to 85. For a human to brute-force codes this would require up to 20 hours, but the makers believe that the bot can break in in a few hours. Read more here.
