Abstract: A tool changer in accordance with the present disclosure comprises: a housing fastened to a manipulator of a robot, wherein the housing is a non-magnetic material; a bar-shaped magnet disposed in the housing; a motor configured to rotate the magnet on a rotation shaft perpendicular to a longitudinal direction of the magnet; and a core configured to derive a path of a magnetic flux by the magnet. The core comprises: a pair of first poles facing both poles of the magnet, when the magnet rotates to be elongated in a first direction; a bridge configured to connect the pair of the first poles and disposed in the housing, wherein the bridge is a magnetic material; a pair of second poles facing the both poles of the magnet, when the magnet rotates to be elongated in a second direction perpendicular to the first direction; and a pair of terminals connected to the second poles and facing a magnetic body disposed outside the housing.

Abstract: Provided are a robot that calculates a level of liquid contained in a liquid container and a method for calculating such liquid level. The robot includes a robot arm to which a tool is attached to an end of the robot arm, a torque sensor disposed on the robot arm and measuring a torque value of the robot arm, and a processor that controls the robot arm and receives the torque value from the torque sensor and calculates information related to the torque value, and calculates the level value of liquid contained in the liquid container based on the information related to the torque value.

Abstract: A robot system can include a main body; a manipulator installed on the main body; a sensor configured to detect an object approaching a restricted region including the manipulator; a camera configured to monitor the restricted region and the object approaching the restricted region; a storage configured to store a material for an operation of the manipulator, the storage including an inlet for receiving the material; a remaining amount sensor configured to detect an amount of the material remaining in the storage; and a controller configured to change the restricted region based on at least one of a result of detection of the remaining amount sensor and image information of the camera, and in response to the sensor detecting that the object is within the restricted region, stop manipulation of the manipulator.

Abstract: Disclosed is a gripper including a pair of main bodies each having an internal space and spaced apart from each other, a pair of openings provided at ends of the pair of main bodies, a pair of moving bodies protruding from the ends of the pair of main bodies through the openings, a pair of inner bodies fixed in the internal space of the pair of main bodies, and a pair of springs configured to be compressed between the inner body and the moving body.

Abstract: Disclosed is a robot and a method for controlling a robot. The robot according to an embodiment of the present disclosure may include an end-effector configured to grip a tool, a tactile sensor disposed in the end-effector, the tactile sensor configured to generate tactile information about an identifier formed on the tool, and a processor configured to cause the end-effector to grip the tool, and determine at least one of a type or a posture of the tool gripped by the end-effector based on the tactile information received from the tactile sensor. Embodiments of the present disclosure may be implemented by executing an artificial intelligence algorithm and/or machine learning algorithm in a 5G environment connected for the Internet of Things.
