Autonomous mobile security robot introduced by Ritsumeikan University — Capable of monitoring via a 360‐degree camera and can be used to detect obstacles and people

Ritsumeikan University has introduced the autonomous mobile security robot named "SQ‐2," manufactured by SEQSENSE, at its Osaka Ibaraki Campus (Ibaraki City, Osaka Prefecture). Notably, this marks the first instance of such an advanced robotic system being deployed within a Japanese university. In March 2019, Ritsumeikan University signed a strategic Digital Transformation (DX) partnership agreement with Mitsubishi Estate to establish a facility operation and management model aligned with the Society 5.0 era, where humans and robots collaborate. As a part of this collaboration, the university has undertaken a series of demonstration experiments on its campus, with the aim of operationalizing diverse robotic systems.

In an endeavor to realize enhanced efficiency in the management of school facilities using security robots, SQ‐2 robots were put into operation in stages, starting in April 2021, with reference to the knowledge of Mitsubishi Estate. This time, the full‐scale introduction of SQ‐2 has been realized by linking it with the elevator, enabling it to automatically move between floors.

SQ‐2 is an autonomous mobile security robot created using advanced technologies such as 3D sensor technology, self‐position estimation algorithms, and real‐time path planning algorithms. Equipped with a proprietary 3D LiDAR, the system has a wide viewing angle and can perform detailed 3D mapping of the property being guarded, detection of moving objects including obstacles and pedestrians, and detection of environmental changes. In addition, by linking the robot with the cloud system, various security operations can be performed remotely from the security base.

For example, the patrol guard moves autonomously to predetermined patrol points and performs monitoring and inspection duties. During these patrols, a front‐mounted camera captures real‐time video footage, which is seamlessly transmitted to the disaster prevention center. Photographs are captured at each patrol point, enabling the guards to review the stored images upon completing their rounds. This allows for the identification of any abnormalities that may have occurred during the patrol. In addition, it is possible carry out surveillance work from a designated security point. The robot is equipped with a camera that offers a comprehensive 360‐degree view of its surroundings. This advanced camera system facilitates real‐time monitoring of the robot's environment through a remote‐control monitor located at the security center. The robot incorporates a call interface that allows it to address inquiries from the field directly.

In addition, the cloud system enables the robot to move autonomously to any point on the map by specifying the desired location. If a suspicious object or injured person is identified during a patrol operation, the robot can be remotely directed to the location in question to verify the situation and communicate with the subject.
