Washington: A cheap 3-D printed robot is capable of breaking a typical Android phone`s 4-digit lock in less than 20 hours.
The Robotic Reconfigurable Button Basher, known more commonly as R2B2, was created by security researchers Justin Engler and Paul Vines , for about 200 dollars, Discovery News reported.
The duo used 10-dollar-servomotors, an open-source Arduino microcontroller, a plastic stylus, a variety of 3D-printed plastic parts and a cheap webcam, which is able to detect when the correct passcode has been used.
R2B2 can be connected to a Mac or Windows PC via USB, which runs a code-cracking program.
Engler and Vines programmed their robot to guess five PIN numbers every half-a-minute, with a 5-second delay after guessing every five times.
At their current rate, R2B2 is capable of going through all 10,000 combinations in less than 20 hours on an Android phone.
