  • MOBILE ROBOT WITH RETURNING MECHANISM
    Publication number: 20150088359
    Abstract: A mobile robot having a returning mechanism includes one or more moving members mounted on a body of the mobile robot; and a cable member connected to one side of the mobile robot so as to supply the mobile robot with electrical power. Further, the mobile robot includes a returning member having a rigidity stronger than the cable member and disposed to wrap the cable member so that the cable member is placed within the returning member; and a take-up unit configured to pull the returning member to keep it taut.

  • Method and apparatus for navigating robot
    Patent number: 8948913
    Abstract: A method of navigating a robot includes creating a robot navigation map using a map database required for navigation of the robot; and creating a path on which no obstacle is located in the map database using the created robot navigation map. Further, the method of navigating the robot includes primarily controlling the robot so that the robot travels along the created path; and secondarily controlling the robot so that the robot avoids an obstacle on the path.

  • METHOD AND APPARATUS FOR CONTROLLING DRIVING OF ROBOT
    Publication number: 20150012164
    Abstract: A method includes constructing map information by obtaining information of environment of a target mowing area, generating a 3-D space path along which the robot having mowing equipment mounted thereon is to move in the target mowing area based on the constructed map information, driving the robot so that the robot travels along the 3-D space path in response to an instruction for executing a mowing mode, extracting a ground area and an obstacle for robot driving by extracting information of a 3-D space when traveling along the 3-D space path, adaptively controlling the driving and mowing mode of the robot based on the extracted ground area and obstacle, and terminating the mowing mode when detecting a completion of the mowing for the target mowing area during the mowing mode.
