This past July, in response to multiple violent interactions between motorists and police officers, two Duke University students came up with the brilliant idea for a robot that could potentially make routine traffic stops safer for both parties. This idea turned into the patent-pending Sentinel Robotic System. Duke senior Vaibhav Tadepalli and PhD candidate Chris Reyes met in 2014 while they were working in the same lab, and have collaborated on multiple startup ventures, including Trapezium Technologies, which was founded to make the lives of law enforcement and citizens safer. The Sentinel Vx1 is a robotic vehicle that's deployed from a police car, and is the primary interaction between the motorist and law enforcement. It was designed to protect the people on either side of a routine traffic stop. Read more at 3DPrint.com: http://3dprint.com/167342/3d-printing-robotic-vehicle/
