The invention discloses a pig rib cutting path planning method based on 3D point cloud, and belongs to the technical field of intelligent cutting and robot automation. High-precision original point cloud of a rib area of a pig carcass is obtained in real time through a 3D visual sensor, and then a segmentation threshold value is dynamically adjusted by introducing a self-adaptive growth factor based on local point cloud density, so that the preprocessed point cloud is robustly and accurately segmented into rib and rib meat areas, and a centerline of a spine and a rib gap are synchronously positioned. And based on the segmentation result, a plurality of independent costal meat communication components are automatically identified and separated through voxelization clustering and graph theory connectivity analysis. For each component, the main extension direction of the component is determined by constructing an axis alignment bounding box, and a series of discrete path points closely attached to the actual surface of the point cloud are generated in the direction. Spatial fitting is carried out by utilizing a cubic polynomial curve to generate a smooth and continuous cutting path which is highly fit with an anatomical structure, and the cutting path is directly converted into an executable track of the robot.

A device for relieving the right shoulder muscles of a right-handed player when playing a stringed instrument, while simultaneously utilizing the resulting free fall force of the right arm to stabilize the instrument. The device consists of a body support that connects the upper bout of the instrument to the player's torso and an armrest that attaches to the rib of the upward-facing lower bout of the instrument, allowing the right upper arm to rest comfortably. When playing a stringed instrument, the right arm must be constantly held in a forward-raised and laterally abducted position due to the instrument's size, using muscle strength to prevent its weight from altering the instrument's playing position. The armrest allows the upper arm to rest comfortably, thus completely relieving the right shoulder muscles. The body support prevents the upper bow of the instrument from being levered forward and upward when the right arm, with its falling force, acts backward and downward on the lower bow. The device causes the force of fall released by the relaxation of the right shoulder muscles to clamp and fix the instrument between the arm, the leg on which it stands, the body support and the contact point between the base of the instrument and the upper body of the player.
