Chinese PC maker Lenovo unveiled a four-legged patrol robot named Morningstar Q1 at the Mobile World Congress Shanghai event this week. Using mixed reality vision, the Q1 robot supports autonomous navigation and comes with an automatic obstacle avoidance function, which Lenovo claims makes it ideal for monitoring industrial parks, malls, campuses, and many other indoor or outdoor sites. Lenovo also unveiled its latest lightweight AR glasses, the Morningstar G2 light AR, at the event. The device can be used for industrial applications including visual management, remote collaboration, and workflow inspection. The AI-recognition feature of the AR glasses also enables their use in museum tours, security, education, and other scenarios, the company added. [Jiemian, in Chinese]
