  • Patent number: 11571973
    Abstract: A method for controlling an electric hand truck includes determining whether user manipulation is present due to a user input on the electric hand truck; and, if there is no user manipulation, then braking an electric motor that drives the wheels of the electric moving vehicle in a softlock manner in which, instead of power being applied to the electric motor, electrodes of the electric motor are short-circuited.

  • Publication number: 20210397961
    Abstract: Disclosed are a method and a system for training an autonomous driving agent on the basis of deep reinforcement learning (DRL). The agent training method according to one embodiment may comprise a step of training an agent through an actor-critic algorithm in a simulation for DRL. The step of training may include inputting first information to an actor network to determine an action of the agent, and inputting second information to a critic to evaluate how helpful the action is to maximizing a reward in the actor-critic algorithm, the second information comprising the first information and additional information.

  • Patent number: 10974395
    Abstract: A method and system for controlling an indoor autonomous robot. A method of controlling an indoor autonomous driving of a robot in a cloud system includes receiving, by the cloud system, first sensing data that is generated by a mapping robot autonomously driving in a target facility using a first sensor that detects the first sensing data with respect to an inside of the target facility; generating an indoor map of the target facility based on the first sensing data; receiving, from a service robot present in the target facility through a network, second sensing data that is generated by the service robot using a second sensor that detects the second sensing data with respect to the inside of the target facility; and controlling an indoor autonomous driving of the service robot with respect to the target facility based on the second sensing data and the generated indoor map.

  • Patent number: 10906573
    Abstract: An electrically driven moving vehicle includes a main body on which an article to be transported is loaded, and a handle provided on one side of the main body. A pair of force sensor units are provided in the handle. A force applied by a user is sensed by the pair of force sensor units to control the operation of electric motors. The user can operate the electrically driven moving vehicle while holding a position convenient for the user rather than a specific position of the handle. In addition, the user can conveniently operate the electrically driven moving vehicle with only one hand, without using both hands.
