Nathan Seidle -Open Source Safe Cracking Robots: Combinations Under 1 Hour
$200 open source robot that cracks combination safes by measuring internal bits and set testing.
Summary
Safe Cracking Challenge
Combination safes provide security through mechanical complexity. A low-cost robotic approach reduces crack times to under an hour through measurement and testing techniques.
Robot Design
Using a motor with high-count encoder, the robot takes measurements of internal bits while the safe remains closed. Measurements expose one combination digit.
Set Testing Method
'Set testing' is a novel method created to decrease time between combination attempts. This technique dramatically improves attack efficiency.
Technology Stack
With 3D printing, Arduino, and powerful magnets, the robot cracks most fire safes. Live cracking demonstrations during the talk showcase practical real-world effectiveness of the approach.
