SR2 is a smart patrol robot designed for industrial parks, internal roads and other large outdoor environments. It combines Ackermann steering with omnidirectional movement to support efficient forward travel, tight-space manoeuvring and rapid turning. With a hybrid AI engine, centimetre-level RTK navigation, multi-sensor perception, real-time interaction and an open IoT ecosystem, SR2 can perform autonomous patrols, risk detection, remote communication, event alerting, video evidence recording and platform-connected workflows.
