  • Patent number: 11655445
    Abstract: A picktool manipulator device collects a specimen from a culture medium. In a first mode of operation, a picktool is allowed to move in an axial direction relative to support structure of the device. A detector may generate a signal in response to movement of the body in the axial direction so as to determine a height at which the picktool contacts the medium. The device may operate in the first mode when collecting a specimen from a culture medium. A second mode of operation constrains or precludes axial movement of the picktool. In some cases, the device may operate in the second mode when receiving a new picktool or discarding a used picktool.
