  • Patent number: 11511432
    Abstract: A method for controlling a robot includes the steps of: deciding whether there is a non-permanent object in a vicinity of the robot; if there is a non-permanent object, deciding whether the object qualifies for extended protection or not; and defining a safety zone around the object which the robot must not enter or in which a maximum allowed speed of the robot is less than outside the safety zone. The safety zone extends to a greater distance from the object if the object qualifies for extended protection than if it does not.

    Abstract: A robot system includes: a robot arm having a plurality of links and joints by which one of the links is connected to another; sensors for determining, for any one of the joints, an angular velocity of the joint and a torque to which the joint is subject; a neural network connected to the sensors, the neural network receiving therefrom angular velocity and torque data, the neural network being trained to distinguish, based on the angular velocity and torque data, between a normal operation condition of the robot arm, a condition in which the robot arm collides with an outside object, and a condition where a person deliberately interacts with the robot arm; and a controller for controlling motion of the robot arm, a mode of operation of which is variable depending on an operation condition signal output by the neural network. One operation mode is a leadthrough mode.
