  • Patent number: 10065667
    Abstract: Driving wheels and non-driving wheels are installed to a lower portion of a case body. The driving wheels are driven by drive devices, respectively. A control device controls a drive operation of the drive devices. An angle sensing device senses a tilt angle of the case body about a rotational axis of the driving wheels. In a case where the tilt angle of the case body, which is sensed with the angle sensing device, is equal to or larger than a predetermined tilt angle in a state where the driving wheels contact a ground while the non-driving wheels are lifted away from the ground, the control device controls the drive devices in such a manner that the case body is held in a self-standing state with the driving wheels while keeping the non-driving wheel away from the ground.

  • Patent number: 10048682
    Abstract: A mobile robot system for allowing a user to easily input a control command of a mobile robot, and a remote control method for the same are disclosed. The mobile robot system and the remote control method thereof can allow a user to easily input control commands regarding the movement and operation of the mobile robot using the jog-dial interface, such that the possibility of causing input errors can be reduced and desired commands can be quickly and efficiently transmitted, resulting in increased user manipulation of the mobile robot system. When the user enters the rotation command of the mobile robot, the mobile robot system can allow the user to perform intuitive interfacing through shuttle manipulation, such that the mobile robot system can facilitate transmission of a movement command having a circular trajectory and the same mobile robot control as in the user-intended control is achieved, resulting in implementation of emotional interface capable of increasing user accessibility.

  • Patent number: 9832940
    Abstract: A control system for an irrigation system is disclosed that is configured to prevent a substantial positional change of the irrigation system while the system is traversing a substantially non-flat terrain, or surface. In an implementation, an irrigation system includes multiple interconnected spans that are supported by multiple tower structures. Each tower structure includes a drive unit for driving a tower structure at a selected speed. The irrigation system also includes a position-determining module configured to determine an actual position of the main section assembly. The irrigation system also includes a control device configured to determine an actual position of the main section assembly, compare the actual position with a desired position of the main section assembly, and to determine that the main section assembly is traversing a substantially non-flat surface.
