AI analyzes human behavior to deploy prompt response

    Equipped with sensors and cameras, Xavier, a robot Singaporean researchers have publicly deployed for trial testing in public areas, sends back data in real-time to a video analytics system with artificial intelligence.
    Insights gained of behaviors in any specified area where an Xavier robot is deployed will inform public officers of proper response to on-ground situations

    SINGAPORE — A robotic machine designed to detect ‘undesirable social behavior’ was finally completed by Singaporean researchers and has now been deployed for trial testing at public areas in the Lion City’s Toa Payoh Central district.

    Xavier was deployed at public areas with high foot traffic to “augment the work of public officers in enhancing public health and safety,” according to the Home Team Science and Technology Agency (HTX), National Environment Agency (NEA), Land Transport Authority (LTA), Singapore Food Agency (SFA), and Housing & Development Board (HDB) in a joint news release.

    Xavier’s designer HTX is in partnership with the Agency for Science, Technology and Research (A*Star). The robot is designed to weave its way through crowds to detect the following activities: smoking in prohibited areas, illegal hawking, improperly parked bicycles within HDB Hub, congregation of more than five people (in line with prevailing safe management measures) and motorized active mobility devices and motorcycles on footpaths.

    HTX says, upon detecting said activities, the robot sends real-time alerts to its command and control centre. While doing so, it displays the appropriate messages to deter the public from such behavior.

    “The aim of deploying Xavier is to reduce the manpower needed for foot patrols and to improve efficiency,” the robot developers said in a media release.

    “It is fitted with different types of sensors as well as safety features and is capable of autonomous navigation and can avoid both stationary as well as dynamic obstacles such as pedestrians or vehicles,” the statement said.

    Xavier is also equipped with cameras that can provide its controllers with a 360-degree view of the robot’s location and can capture images and videos in dim light as well as in the dark.

    “Data captured from Xavier’s cameras are streamed to a video analytics system with artificial intelligence capability developed by HTX’s in-house computer vision engineers.

    “With real-time sensing and analysis, public officers can gain insights on the these behaviors more efficiently and effectively, and activate additional resources to respond to on-ground situations when necessary,” says Chee Wee Kiang, director at HTX Robotics, Automation and Unmanned systems Centre of Expertise.

    Public officers at the robot’s control center will be guided by an interactive dashboard aboard the robot that allows control to receive real-time information and to respond to incidents on the ground via a two-way intercom system or using pre-recorded audio messages.

    “HTX’s ground robots are highly versatile and can be customized for broad and widespread application in different fields and operational environments,” syas Mr Chee. (TRC/The MiNT)
