Abstract: A display apparatus including a display, and a support member including a fixing member to be fixed to a wall surface, a mounting member on which the display is to be mounted and connected to the fixing member, and a connector attaching the mounting member to the fixing member and supported for rotation in forward, backward, leftward, and rightward directions, in which the connector includes a plurality of rotatable supports connected to the fixing member and supported for rotation in the leftward and rightward directions, a plurality of movable supports connected to the rotatable supports and supported for slidable movement in the leftward and rightward directions, and a plurality of connecting supports connected to the mounting member and supported for rotation in the forward and backward directions, and connected to the movable supports to rotate in the leftward and rightward directions.

Abstract: An intelligent foot of a humanoid robot, which enables the robot to safely walk in balance even on the irregular ground, is disclosed. The walking robot's foot includes a backpart unit with a leg which is rotatably installed at the center thereof, and a forepart unit which is rotatably connected to the front of the backpart unit by a foot part connector, wherein 6-axis force/moment sensors are installed on the bottom of the backpart unit and the bottom of the forepart unit, respectively. Further, walking robot's foot includes a backpart unit with a leg which is rotatably installed at the center thereof, and at least two toes which are rotatably connected to the front of the backpart unit by foot part connectors, wherein a 6-axis force/moment sensor is installed on the bottom of the backpart unit, and short shaft sensors are installed on the bottom of the toes.
