  • Patent number: 12194642
    Abstract: The present disclosure relates to a kinematics calibration method for a robot with multiple degrees of freedom. The robot includes a base, an end effector, and a plurality of links connected by joints. The method includes locking part of the multiple degrees of freedom by limiting the base and the end effector impose a limitation of degree of freedom; moving the robot to perform a first movement and accordingly obtaining a first set of data associated with joint angles and a first actual motion of the end effector; calculating a first theoretical motion of the end effector based on the first set of data and initial kinematics parameters; and updating the initial kinematics parameters of the robot to obtain a first set of updated kinematics parameters based on the first theoretical motion and the first actual motion.

  • Patent number: 12161311
    Abstract: An auxiliary apparatus for minimally invasive surgery is provided. The auxiliary apparatus includes an in vivo device, an in vitro device, a locating probe and a control system. The in vitro device includes an in vitro magnetic field generating element and a driving mechanism. The in vivo device includes a magnetic auxiliary member and a clip. The locating probe includes a magnetic field sensor. The auxiliary apparatus can achieve the effects of easy control of the mucosa curling angle, high repeatability of operation, fast speed, high safety and reliability for the mucosa to be dissected in any spatial orientation.
