System description

Source: Markus Eich, DFKI

The SentryBot Indoor is a mobile security robot, which is able to patrol autonomously in indoor environments. With its security-related application sensors, the system is able to detect movement of persons and trigger an alarm. To achieve this, the robot is equipped with a pan-tilt camera, four passiv infrared sensors and four radar sensors. The latter is able to detect movements of people within a distance of 12 meters, even through walls. Additionally, the robot uses a laser range finder to navigate autonomously and to generate an obstacle map of its environment.

This autonomous navigation enables the robot to reach a re-charging station without user interference and therefore provides the robot with 24h operating time. The SentryBot Indoor robot is the first step to a heterogeneous multi-robot system, which, in future, will be able to fulfill security missions in co-operation with security personnel (mixed human robot teams). For this task, the focus is on seamless integration into existing security systems and concepts.
