  • Publication number: 20260034687
    Abstract: An industrial robot including a base; a manipulator movable relative to the base, the manipulator being hermetically closed and including a plurality of joints; a plurality of transmissions inside the manipulator, each transmission being associated with a unique joint; a plurality of motors inside the manipulator, each motor being arranged to drive a joint via the transmission associated with the joint; an outlet inside the manipulator distal of a distal transmission among the plurality of transmissions; a gas line passing between the base and the outlet; and a gas conducting structure configured to conduct a gas flow between the outlet and the base inside the manipulator, the gas conducting structure including, for each joint, at least one channel arranged to conduct the gas flow through the joint.

  • Publication number: 20250263162
    Abstract: Different solutions to stop automatically a vessel, which includes at least a first cycloidal propeller unit and a second cycloidal propeller unit, are disclosed. During a stopping procedure motion control values of at least the first cycloidal propeller unit are adjusted to cause, while maintaining a movement direction of the vessel to be according to a latest steering command, the first cycloidal propeller unit to brake in a first mode or in a second mode. In the first mode the main wheel is rotating, and blades of the cycloidal propeller unit are rotated to change a thrust direction towards to a reverse thrust direction. In the second mode either the main wheel is kept in a first position and the blades are positioned individually towards a corresponding predetermined angle to the movement direction or the blades are kept in first positions and the main wheel is rotated.

  • Patent number: 11207781
    Abstract: Disclosed are systems and methods to provide a method for calibrating a touchscreen coordinate system of a touchscreen with an industrial robot coordinate system of an industrial robot for industrial robot commissioning and industrial robot system and control system using the same. In one form the systems and methods include attaching an end effector to the industrial robot; (a) moving the industrial robot in a compliant way until a stylus of the end effector touches a point on the touchscreen; (b) recording a position of the stylus of the end effector in the industrial robot coordinate system when it touches the point of the touchscreen; (c) recording a position of the touch point on the touchscreen in the touchscreen coordinate system; and calculating a relation between the industrial robot coordinate system and the touchscreen coordinate system based on the at least three positions of the end effector stylus and the at least three positions of the touch points.
