  • Patent number: 11697206
    Abstract: An acceleration adjustment apparatus may include a load calculation unit that calculates a peak value of a load that is estimated to act on a robot, based on a motion equation regarding a motion of the robot and a value of an acceleration of a joint of the robot in motion. The acceleration adjustment apparatus may further include an acceleration adjustment unit that executes at least one of a first adjustment in which, when the peak value of the load calculated by the load calculation unit is greater than a target value of the load acting on the robot when the robot is moving, the acceleration is adjusted to decrease, and a second adjustment in which, when the peak value of the load calculated by the load calculation unit is less than the target value, the acceleration is adjusted to increase.

  • Publication number: 20210260755
    Abstract: A gripping posture evaluation apparatus includes a gripping posture deriver that derives a gripping posture in which a robot hand (H) in a robot (RB) grips a workpiece, a load index calculator that calculates a load index value indicating a load to the robot (RB) gripping and transporting the workpiece with the hand (H) in the gripping posture derived by the gripping posture deriver, and a gripping posture evaluator that evaluates the gripping posture by determining whether the gripping posture is appropriate based on the load index value calculated by the load index calculator. In response to the gripping posture evaluator determining that the gripping posture is inappropriate, derivation of a new gripping posture by the gripping posture deriver, calculation of a load index value by the load index calculator, and evaluation by the gripping posture evaluator are repeated.
