Homemade robot cracks a safe at Def Con

A group of hackers have built a robot that can crack a safe. A team from SparkFun Electronics in Colorado took their robot to the underground hacking convention, Def Con in Las Vegas. They bought a SentrySafe safe the day before the demonstration and opened it onstage Friday. The robot took about 30 minutes to crack the safe, discovering the combination was 51.36.93. The audience clapped and cheered when the safe was opened.
