    Abstract: A robot determines whether or not an operator or an object is jammed between a robot arm and an external structure, classifies an area in which an end portion of the robot arm moves into a restricted area and an unrestricted area, and sets a restriction period. If a period after detection of the jam is in the restriction period and the end portion is in the restricted area, restriction on movement is imposed on one or more joints of the robot arm. The restriction on movement is a stoppage of movement of one or more joints. If the period after detection of the jam is after the restriction period, the restriction on movement is removed. If the period after detection of the jam is in the restriction period and the end portion is in the unrestricted area, the restriction on movement is not imposed on the joints.

    Abstract: A robot hand apparatus includes a holder having a bendable sucking surface that sucks an object; a magnetic elastic body arranged at the holder and formed of an elastic material containing magnetic particles; and a magnetic-field generator that is arranged at the holder and applies a magnetic field to the magnetic elastic body to change a coefficient of elasticity of the magnetic elastic body. When the magnetic-field generator applies a magnetic field to the magnetic elastic body, a flexible portion and a hardened portion having a bigger coefficient of elasticity than that of the flexible portion are formed in the magnetic elastic body. When the holder holds the object, in a state in which the sucking surface is bent at a position corresponding to the flexible portion, a region of the sucking surface between the position and a distal end of the holder sucks the object.

    Abstract: A robot arm temporarily stops when a contact detector detects contact. A holding motion selecting unit then selects one of continuously stopped motion, directionally limited motion, and directionally unlimited motion in accordance with information including one or both of a distance between the robot arm and a contacted object and force applied to the robot arm by a person. A motion controller causes the selected motion to achieve holding motion.

    Abstract: A robot includes an arm mechanism that operates in accordance with a first motion pattern for supporting a user with a standing-up motion which starts in a sitting posture and finishes in a standing posture, a control unit that (i) acquires first information used to identify a predetermined position of the arm mechanism corresponding to a half-crouching posture of the user during a motion in accordance with the first motion pattern and (ii) detects whether the current position of the arm mechanism operating in accordance with the first motion pattern is included in a first range including the predetermined position identified by the first information, and a presentation unit that presents a first signal if the control unit detects that the position of the arm mechanism is included in the first range.
