The SMP Robotics S5 Security Guard from Robotic Assistance Devices (RAD) is an autonomous unmanned ground vehicle that leverages advanced navigation, obstacle avoidance sensors and intelligent mechanics to support traditional manned guard services. RAD offers end users and guard service providers the ability to augment existing security solutions to improve safety, increase situational awareness and streamline operations with the Robot-as-a-Service (RaaS) model. The security robot, which is based on advanced artificial intelligence, also reduces liability by removing security personnel from potentially dangerous situations.
