The explosives detection system plays an important role in the counter-terrorism field. For the lack of automated trace explosives detection system, we design a manipulator-based intelligent trace explosives detection system for baggage, named AnBot. As far as we know, it is the first automated trace explosives detection system in China. To avoid reducing the detector's sensitivity and selectivity to explosives, AnBot uses a UR3 manipulator to set up its sampling subsystem. To set up the system well and quickly, we build a ROS-based software framework for AnBot. Finally, the first version of AnBot was designed to accomplish the automated trace explosives detection process by itself. On the one hand, it promotes trace explosives detectors' further widespread use. On the other hand, the proposed system makes it possible to incorporate the trace explosives detection system into the intelligent security network.
