  • Publication number: 20230219220
    Abstract: The present application relates to the field of error detection technology. An error detection method and a robot system are provided. The error detection method includes: obtaining a target pose of an end of an operating arm; acquiring a positioning image; recognizing, in the positioning image, a plurality of pose identifications located on the end of the operating arm; recognizing, based on the plurality of pose identifications, an angle identification located on the end of the operating arm, the angle identification having a position association relationship with a first pose identification of the plurality of pose identifications; determining, based on the angle identification and the plurality of pose identifications, an actual pose of the end of the operating arm; and generating, in response to the target pose and the actual pose meeting an error detection condition, a control signal related to a fault.

  • Publication number: 20230181873
    Abstract: A growable continuum instrument includes a growable tube and one or more serially connected continuum structures. The growable tube includes an inner layer, an outer layer, and a fluid chamber between the inner and outer layers. The growable tube includes a turnable region where the inner and outer layers are connected and turnable. The continuum structure is located in the growable tube. The continuum structure includes a plurality of spacer discs and a plurality of connecting structures. The connecting structure includes one or more flexible structural bones, the two ends of which are respectively fixedly connected with the adjacent spacer discs, and are distributed along the circumferential direction of the spacer discs. The plurality of connecting structures include at least a first and second connecting structures, and the flexible structural bones of the first and second connecting structures are distributed differently along the circumferential direction of the spacer disc.
