Abstract: A picking system includes a picking robot, a shape obtainer, and circuitry. The picking robot is configured to hold an object. The shape obtainer is configured to obtain shape information of the object. The circuitry is configured to estimate a weight of the object based on the shape information obtained by the shape obtainer; and control the picking robot to hold the object based on the weight estimated by the weight estimator.
